Understanding assignment risk in Level 3 and 4 options strategies

E*TRADE from Morgan Stanley

With all options strategies that contain a short option position, an investor or trader needs to keep in mind the consequences of having that option assigned , either at expiration or early (i.e., prior to expiration). Remember that, in principle, with American-style options a short position can be assigned to you at any time. On this page, we’ll run through the results and possible responses for various scenarios where a trader may be left with a short position following an assignment.

Before we look at specifics, here’s an important note about risk related to out-of-the-money options: Normally, you would not receive an assignment on an option that expires out of the money. However, even if a short position appears to be out of the money, it might still be assigned to you if the stock were to move against you just prior to expiration or in extended aftermarket or weekend trading hours. The only way to eliminate this risk is to buy-to-close the short option.

  • Short (naked) calls

Credit call spreads

Credit put spreads, debit call spreads, debit put spreads.

  • When all legs are in-the-money or all are out-of-the-money at expiration

Another important note : In any case where you close out an options position, the standard contract fee (commission) will be charged unless the trade qualifies for the E*TRADE Dime Buyback Program . There is no contract fee or commission when an option is assigned to you.

Short (naked) call

If you experience an early assignment.

An early assignment is most likely to happen if the call option is deep in the money and the stock’s ex-dividend date is close to the option expiration date.

If your account does not hold the shares needed to cover the obligation, an early assignment would create a short stock position in your account. This may incur borrowing fees and make you responsible for any dividend payments.

Also note that if you hold a short call on a stock that has a dividend payment coming in the near future, you may be responsible for paying the dividend even if you close the position before it expires.

An early assignment generally happens when the put option is deep in the money and the underlying stock does not have an ex-dividend date between the current time and the expiration of the option.

Short call + long call

(The same principles apply to both two-leg and four-leg strategies)

This would leave your account short the shares you’ve been assigned, but the risk of the position would not change . The long call still functions to cover the short share position. Typically, you would buy shares to cover the short and simultaneously sell the long leg of the spread.

Pay attention to short in-the-money call legs on the day prior to the stock’s ex-dividend date, because an assignment that evening would put you in a short stock position where you are responsible for paying the dividend. If there’s a risk of early assignment, consider closing the spread.

Short put + long put

Early assignment would leave your account long the shares you’ve been assigned. If your account does not have enough buying power to purchase the shares when they are assigned, this may create a Fed call in your account.

However, the long put still functions to cover the position because it gives you the right to sell shares at the long put strike price. Typically, you would sell the shares in the market and close out the long put simultaneously.

Here's a call example

  • Let’s say that you’re short a 100 call and long a 110 call on XYZ stock; both legs are in-the-money.
  • You receive an assignment notification on your short 100 call, meaning you sell 100 shares of XYZ stock at 100. Now, you have $10,000 in short stock proceeds, your account is short 100 shares of stock, and you still hold the long 110 call.
  • Exercise your long 110 call, which would cover the short stock position in your account.
  • Or, buy 100 shares of XYZ stock (to cover your short stock position) and sell to close the long 110 call.

Here's a put example:

  • Let’s say that you’re short a 105 put and long a 95 put on XYZ stock; the short leg is in-the-money.
  • You receive an assignment notification on your short 105 put, meaning you buy 100 shares of XYZ stock at 105. Now, your account has been debited $10,500 for the stock purchase, you hold 100 shares of stock, and you still hold the long 95 put.
  • The debit in your account may be subject to margin charges or even a Fed call, but your risk profile has not changed.
  • You can sell to close 100 shares of stock and sell to close the long 95 put.

Long call + short call

Debit spreads have the same early assignment risk as credit spreads only if the short leg is in-the-money.

An early assignment would leave your account short the shares you’ve been assigned, but the risk of the position would not change . The long call still functions to cover the short share position. Typically, you would buy shares to cover the short share position and simultaneously sell the remaining long leg of the spread.

Long put + short put

An early assignment would leave your account long the shares you’ve been assigned. If your account does not have enough buying power to purchase the shares when they are assigned, this may create a Fed call in your account.

All spreads that have a short leg

(when all legs are in-the-money or all are out-of-the-money)

Pay attention to short in-the-money call legs on the day prior to the stock’s ex-dividend date because an assignment that evening would put you in a short stock position where you are responsible for paying the dividend. If there’s a risk of early assignment, consider closing the spread.

However, the long put still functions to cover the long stock position because it gives you the right to sell shares at the long put strike price. Typically, you would sell the shares in the market and close out the long put simultaneously.

early assignment of options

Ever been blindsided by an unexpected traffic ticket in the mail? 

You knew driving came with its set of potential consequences, yet you took to the road regardless. Suddenly, you’re left with a tangible obligation to pay. This unforeseen shift, where what was once a mere possibility becomes an immediate reality, captures the spirit of options assignment within the vast realm of options trading.

Diving into the details, option assignment serves as the bridge between the abstract realm of rights and the concrete world of duties in this field. It’s that unassuming piece in the machinery that can, without warning, change the entire game – often carrying notable financial repercussions. In a domain where every move has implications, truly grasping option assignment is foundational, ensuring not just survival but genuine success.

Join us in this comprehensive exploration of option assignment, arming traders of all experience levels with the knowledge to sail these intricate seas with assuredness and accuracy.

What you’ll learn

What is Options Assignment?

How options assignment works, identifying option assignment , examples of option assignment, managing and mitigating assignment risks, what option assignment means for individual traders.

  • Conclusion 

Dive into the realm of options trading and you’ll find a tapestry of processes and potential. “Options assignment” is one pivotal cog in this intricate machine. To a newcomer, this term might seem a tad daunting. But a step-by-step walk-through can demystify its core.

In its simplest form, options assignment means carrying out the rights specified in an option contract. Holding an option allows a trader the choice to buy or sell a particular asset, but there’s no compulsion. The moment they opt to use this right, that’s when options assignment kicks in.

Think of it this way: You’ve got a ticket (option) to a show (buy or sell an asset). You decide if and when to attend. When you make the move, that transition is the options assignment.

There are two main types of option assignments:

  • Call Option Assignment : Triggered when a call option holder exercises their right. The seller of the option then steps into the spotlight, bound to sell the asset at the agreed-upon price.
  • Put Option Assignment : Conversely, if a put option holder steps forward, the seller of the put takes the stage. Their role? To buy the asset at the specified rate.

To truly grasp options assignment, one must understand the dance between rights and obligations in options trading.

When a trader buys an option, they’re essentially reserving a right, a possible move. On the other hand, selling an option translates to accepting a duty if the option’s holder chooses to play their card.

Rights with Call Options: Buying a call option grants you a special privilege. You can procure the underlying asset at a set price before the option expires. If you choose to exercise this right, the one who sold you the call gets assigned. Their task? Handing over the asset at that set price.

Obligations with Put Options: Securing a put option empowers you to sell the underlying at a pre-decided rate. Should you exercise this, the put’s seller steps up, committed to buying the asset at the given rate.

Several factors steer the course of options assignment, including intrinsic value, looming expiration dates, and current market vibes. To stay ahead of these influences, many traders utilize option trade alerts for timely insights. And remember, while many options might find buyers, not all see execution. Hence, not every seller will get assigned. For traders, understanding this rhythm is vital, shaping many strategies in options trading. 

In the multifaceted world of options trading, discerning option assignment straddles the line between art and science. While no technique guarantees surefire results, several pointers and signals can wave a flag, hinting at an impending assignment.

In-the-Money Options : A robust sign of a looming assignment is the option’s stance relative to its strike price. “In-the-money” refers to an option’s moneyness , and plays a pivotal role in the behavior of option holders. Deeply in-the-money (ITM) options amplify the odds of assignment. An ITM call option, where the market price of the asset towers above the strike price, encourages the holder to exercise and swiftly offload the asset on the market. Conversely, an ITM put option, where the market price trails significantly behind the strike price, incentivizes the holder to scoop up the asset in the market and then exercise the option to vend it at the loftier strike price.

Expiration’s Shadow: The ticking clock of an expiring option raises the assignment stakes, especially if it remains ITM. Many traders make their move just before the eleventh hour to capitalize on their gains.

Dividend Dates in Focus: Call options inching toward expiry ahead of a dividend date, especially if they’re ITM, stand at an elevated assignment crosshair. Option aficionados might play their call options to pocket the dividend, which they’d bag if they possess the core shares.

Extrinsic Value’s Decline : A diminishing time or extrinsic value of an option elevates its exercise odds. When intrinsic value dominates an option’s worth, a holder might be inclined to cash in on this value.

Volume & Open Interest Dynamics : A sudden surge in trading or a dip in open interest can be telltale signs. Understanding volume’s role is crucial as such fluctuations might hint at traders either hopping in or out, suggesting possible exercises and assignments. 

Navigating the Post-Assignment Terrain

Grasping the ripple effects of option assignment is vital, highlighting the immediate responsibilities and potential paths for both the buyer and seller.

For the Option Seller:

  • Call Option Assignment : For a trader who’s sold a call option, assignment means they’re on the hook to hand over the underlying shares at the strike price. If they’re short on shares, a market purchase is in order—potentially at a loss if market prices overshoot the strike.
  • Put Option Assignment: Assignment on a peddled put option necessitates the trader to buy the shares at the strike price . If this price overshadows the market rate, losses loom.

For the Option Buyer:

  • Call Option Play : Exercising a call lets the buyer snap up shares at the strike price. They can either nestle with them or trade them off.
  • Put Option Play: Exercising a put gives the buyer the reins to sell their shares at the strike price. This play often pays off when the market rate is dwarfed by the strike, ensuring a tidy profit on the dispensed shares.

Post-assignment, all involved must be on their toes, knowing what triggers margin calls , especially if caught off-guard by the assignment. Tax implications may also hover, influenced by the trade’s nature and the tenure of the position.

Being savvy about these subtleties and gearing up for possible turns of events can drastically refine one’s journey through the options trading maze. 

Call Option Assignment Scenario

Imagine an investor purchases an Nvidia ( NVDA ) call option at a strike price of $435, hoping that the price of the stock will ascend after finding out that they may be forced to move out of some countries . The option is set to expire in a month. Soon after, not only did NVDA rebound from the news, but they reported very strong quarterly earnings, propelling the stock to $455.

Spotting the favorable trend, the investor opts to wield their right to purchase the stock at the agreed strike price of $435, despite its $455 market value. This initiates the option assignment.

The other investor, having sold the option, must now part with their NVDA shares at $435 apiece. If they’re short on stocks, they’d have to fetch them at the going rate of $455 and let them go at a deficit. The first investor, however, stands at a crossroads: retain the shares in hopes of further gains or swiftly trade them at $455, reaping a neat sum. 

Put Option Assignment Scenario

Let’s visualize an investor who speculates a dip in the share price of V.F. Corporation ( VFC ) after seeing news about an activist investor causing shares to jump almost 14% in a day . To hedge their bets, they secures a put option from another investor at a strike price of $18.50, set to lapse in a month.

Fast forward a week, let’s say VFC divulges lackluster quarterly figures, causing the stock to dive to $10. The first investor, seizing the moment, employs their put option, electing to sell their shares at the $18.50 strike price.

When the assignment bell tolls, the other investor finds himself bound to buy the shares from the first investor at the agreed $18.50, a rate that overshadows the current $10 market value. The first investor thus sidesteps the market slump, securing a favorable sale. The other investor, however, absorbs a loss, acquiring stocks at a premium to their market worth.

The realm of options trading is akin to navigating a dynamic river, demanding a sharp comprehension of the risks that lie beneath its surface. A predominant risk that traders often encounter is assignment risk. When one assumes the role of an option seller, they inherit the duty to honor the contract if the buyer opts to exercise. Grasping the gravity of this can make the difference, underscoring the necessity of adept risk management.

A savvy approach to temper assignment risk is by keeping a vigilant eye on the extrinsic value of options. Generally, options rich in extrinsic value tend to resist early assignment. This resistance emerges as the extrinsic value dwindles when the option dives deeper in-the-money, thereby tempting the holder to exercise.

Furthermore, economic currents, ranging from niche corporate updates to sweeping market tides, can be triggers for option assignments. Staying attuned to these economic ripples equips traders with the vision needed to either tweak or maintain their positions. For example, traders may opt to sidestep selling options that are deeply in-the-money, given their higher susceptibility to assignments due to their shrinking extrinsic value.

Incorporating spread tactics, like vertical spreads  or iron condors, furnishes an added shield. These strategies can dampen the risk of assignment since one part of the spread frequently balances the risk of its counterpart. Should the specter of a short option assignment hover, traders might contemplate ‘rolling out’ their stance. This move entails repurchasing the short option and subsequently selling another, possibly at a varied strike rate or a more distant expiry.

Yet, despite these protective layers, it remains pivotal for traders to brace for possible assignments. Maintaining ample liquidity, be it in capital or necessary shares, can avert unfavorable scenarios like hasty liquidations or stiff margin charges. Engaging regularly with brokers can also shed light, occasionally offering a heads-up on looming assignments.

In conclusion, the bedrock of risk management in options trading is rooted in perpetual learning. As traders hone their craft, their adeptness at forecasting and navigating assignment risks sharpens.

In the intricate world of options trading, option assignments aren’t just nuanced details; they’re pivotal moments with deep-seated implications for individual traders and the health of their portfolios. Beyond the immediate financial aftermath, assignments can reshape trading plans, risk dynamics, and the overarching path of an investor’s journey.

At its core, option assignments can transform a trader’s asset landscape. Consider a trader who’s short on a call option. If they’re assigned, they might be compelled to supply the underlying stock. This can result in a rapid stock outflow from their portfolio or, if they don’t possess the stock, birth a short stock stance. On the flip side, a trader short on a put option who faces assignment may find themselves buying the stock at the strike price, thereby dipping into their cash reserves.

These immediate shifts can generate broader portfolio ripples. An unexpected gain or shedding of stocks can jostle a trader’s asset distribution, veering it off their envisioned path. If, for instance, a trader had charted a particular stock-to-cash distribution or a meticulous diversification blueprint, an option assignment might throw a spanner in the works.

Additionally, assignments can serve as a real-world litmus test for a trader’s risk-handling prowess . A surprise assignment might spark margin calls for those not sufficiently fortified with capital. It stands as a poignant nudge about the essence of ensuring liquidity and safeguarding against the unpredictable whims of the market.

Strategically speaking, recurrent assignments might signal it’s time for traders to recalibrate. Are the options they’re offloading too submerged in-the-money? Have they factored in pivotal market shifts that might heighten early exercise odds? Such reflective moments can pave the way for refining and elevating trading methods. 

In the multifaceted world of options trading, option assignment stands out as both a potential boon and a challenge. Far from being a simple checkbox in the process, its ramifications can mold the contours of a trader’s portfolio and steer long-term tactics. The importance of comprehending and adeptly managing option assignment resonates, whether you’re dipping your toes into options for the first time or weaving through intricate trades with seasoned expertise. 

Furthermore, mastering options trading is about integrating its myriad concepts into a cohesive playbook. Whether it’s differentiating trading strategies like the iron condor from the iron butterfly strategy or delving deep into the nuances of option assignments, each component enriches the narrative of a trader’s odyssey. As markets shift and new hurdles arise, a solid grasp of foundational principles remains an invaluable asset. In this perpetual dance of learning and evolution, may your trading maneuvers always be well-informed, proactive, and adept. 

Understanding Options Assignment: FAQs

What factors influence the likelihood of an option being assigned.

Several factors come into play, including the option’s intrinsic value , the time remaining until expiration, and upcoming dividend announcements. Options that are deep in the money or nearing their expiration date are more likely to be assigned.

Are Some Option Styles More Prone to Assignment than Others?

Absolutely. When considering different option styles , it’s essential to note that American-style options can be exercised at any point before their expiration, which means they face a higher risk of early assignment. In contrast, European-style options can only be exercised at expiration.

How Do Current Market Trends Impact Assignment Risk?

Factors like market volatility, notable price shifts, and external economic happenings can amplify the chances of an option being assigned. For example, an option might be assigned before a company’s ex-dividend date if the expected dividend outweighs the weakening of theta decay .

Can Traders Reverse or Counter the Effects of an Option Assignment?

Once an option has been assigned, it’s set in stone. However, traders can maneuver within the market to balance out the implications of the assignment, such as procuring or selling the underlying asset.

Are There Any Fees Tied to Option Assignments?

Indeed, brokers usually impose a fee for both assignments and exercises. The specific fee can differ depending on the broker, making it essential for traders to understand their brokerage’s charging scheme.

Key Takeaways

  • Learn the basics of options exercise and options assignment
  • Understand the difference between in-the-money and out-of-the-money options
  • The surest way to avoid exercise or assignment is to liquidate or roll a position ahead of expiration, but remember, assignment of a short option can happen at any time 

So your trading account has gotten options approval and you recently made that first trade—say, a long call in XYZ with a strike price of $105. Then the option expires, and at the time, XYZ is trading at $105.30.

Wait. The stock’s above the strike. Is that in the money (ITM) or out of the money (OTM)? Do I need to do something? Do I have enough money in my account? Help!

Please, please, please: Don’t be that trader. The time to learn the mechanics of options expiration is before you make your first trade. Opening an account at TD Ameritrade entitles you to a host of free trading education, including an entire course on options trading. (And at the end of this article, you’ll find a short video covering the basics.)

Here’s a guide to help you navigate options exercise and assignment — along with a few other basics.

Memorize This Table (or Cut It Out and Paste It to Your Screen)

The buyer (“owner”) of an option has the right, but not the obligation, to exercise the option on or before expiration. A call option gives the owner the right to buy the underlying security; a put option gives the owner the right to sell the underlying security.

Conversely, when you sell an option, you may be assigned the underlying asset—at any time regardless of the ITM amount—if the option owner chooses to exercise. The option seller has no control over assignment and no certainty as to when it could happen.

An option will likely be exercised if it’s in the option owner’s best interest to do so, meaning if it’s advantageous from a price standpoint for the owner to take or to close a position in the underlying security at the strike price rather than at the prevailing price in the open market. After the close on expiration day, ITM options may be automatically exercised, whereas OTM options are not and typically expire worthless (often referred to as being “abandoned”). The table below spells it out.

This assumes a position is held all the way through expiration. Of course, you typically don’t need to do that. And in many cases, the usual strategy is to close out a position ahead of the expiration date. We’ll revisit the close-or-hold decision in the next section and look at ways to do that. But assuming you do carry the options position until the end, there are a few things you need to consider:

  • Know your specs .Each standard equity options contract controls 100 shares of the underlying stock. That’s pretty straightforward. Non-standard options may have different deliverables. Non-standard options can represent a different number of shares , shares of stock of more than one company, or underlying shares and cash. Other products—such as equity index options or options on futures—have  different contract specs .
  • Offsetting positions will match and close .Suppose you’re long 300 shares of XYZ and short one ITM call that’s assigned. That call is deliverable into 100 shares, so you’ll be left with 200 shares of XYZ if the option is assigned.

Exercise and Assignment: It’s Not Just at Expiration!

Standard U.S. equity options are American-style options, meaning they can be exercised anytime before expiration. If you’re short an option that’s deep ITM, it’s possible you’ll get assigned early. ITM short call positions are particularly vulnerable if a company is about to issue a dividend. ( Learn more about options and dividend risk .)

  • It’s automatic, for the most part . If an option is ITM by as little as $0.01 at expiration, it will automatically be exercised for the buyer and assigned to a seller. However, there’s something called a Do Not Exercise request that a long option holder can submit if they want to abandon an option. In such a case, it’s possible that a short ITM position might not be assigned. For more, see the note below on pin risk, or refer to this advanced options expiration article . 
  • You’d better have enough cash . If an XYZ option is exercised or assigned and you don’t have an offsetting position, you’ll essentially be exchanging an options position for a position in the underlying. A long call or a short put will result in a long position in XYZ; a short call or a long put will result in a short position in XYZ. For long stock positions, you need to have enough cash to cover the purchase or else you’ll be issued a margin call, which you must meet by adding funds to your account. But that timeline may be short, and the broker, at its discretion, has the right to liquidate positions in order to meet a margin call. If exercise or assignment involves taking a short stock position, you need a margin account and sufficient funds in the account to cover the margin requirement.
  • Short equity positions are risky business . An uncovered short call or a long put, if assigned or exercised, will result in a short position. If you’re short a stock, you have potentially unlimited risk because there’s no limit to the price increase of a security. There’s also no guarantee the brokerage firm can continue to maintain that short position for an unlimited time period. So if you’re a newbie, it’s generally inadvisable to carry a position into expiration if there’s a chance you might end up with a short stock position.   

A note on pin risk : It’s rare, but occasionally a stock settles right on a strike price at expiration. So if you were short the 105 calls and XYZ settled at exactly $105, there would be no automatic assignment, but depending on the actions taken by the option holder, you may or may not be assigned—and you may not be able to trade out of any unwanted positions until the next business day.

But it goes beyond the exact price issue. What if an option is ITM as of the market close, but news comes out after the close (but before the exercise decision deadline) that sends the stock up or down through the strike price? Remember: The holder of the option could submit a Do Not Exercise request. 

This uncertainty and potential exposure is called pin risk, and the best way to avoid it is to close your position before expiration.

The Decision Tree: How to Approach Expiration

As expiration approaches, you have three choices. Depending on the circumstances—and your objectives and risk tolerance—any of these might be the best decision for you. 

Are options the right choice for you?

While options trading involves unique risks and is definitely not suitable for everyone, if you believe options trading fits with your risk tolerance and overall investing strategy, TD Ameritrade can help you pursue your options trading strategies with powerful trading platforms, idea generation resources, and the support you need.

Let the chips fall where they may . Some positions may not require as much maintenance. An options position that’s deeply OTM will likely go away on its own, but occasionally an option that’s been left for dead springs back to life. If it’s a long option, that might feel like a windfall; if it’s a short option that could’ve been closed out for a penny or two, you might be kicking yourself for not doing so.

Conversely, you might have a covered call against long stock, and the strike price was your exit target. For example, if you bought XYZ at $100 and sold the 110-strike call against it, and XYZ rallies to $113, you might be content with the $10 profit (plus the premium you took in when you sold the call, but minus any transaction costs). In that case, you can let assignment happen.

Close it out . If you’ve met your objectives for a trade—for better or worse—it might be time to close it out. Otherwise, you might be exposed to risks that aren’t commensurate with any added return potential (like the short option that could’ve been closed out for next to nothing, then suddenly came back into play).

The close-it-out category also includes ITM options that could result in an unwanted position or the calling away of a stock you didn’t want to part with. And remember to watch the dividend calendar. If you’re short a call option near the ex-dividend date of a stock, the position might be a candidate for early exercise. If so, you may want to consider getting out of the position well in advance—perhaps a week or more. Keep in mind, there is no guarantee that there will be an active market for an options contract, so it is possible to end up stuck and unable to close an options position.        

Roll it to something else . This is the third choice. Rolling is essentially two trades executed as a spread. One leg closes out the existing option; the other leg initiates a new position. For example, suppose you’re short a covered XYZ call at the July 105 strike, the stock is at $103, and the call’s about to expire. You could roll it to the August 105 strike. Or, if your strategy is to sell a call that’s $5 OTM, you might roll to the August 108 call. Keep in mind that rolling strategies can entail additional transaction costs, including multiple contract fees, which may impact any potential return. 

The Bottom Line on Options Expiration

You don’t enter an intersection and  then  check to see if it’s clear. You don’t jump out of an airplane and  then  test the rip cord. So do yourself a favor. Get comfortable with the mechanics of options expiration before you make your first trade. Your beating heart will thank you.

The Risks of Options Assignment

early assignment of options

Any trader holding a short option position should understand the risks of early assignment. An early assignment occurs when a trader is forced to buy or sell stock when the short option is exercised by the long option holder. Understanding how assignment works can help a trader take steps to reduce their potential losses.

Understanding the basics of assignment

An option gives the owner the right but not the obligation to buy or sell stock at a set price. An assignment forces the short options seller to take action. Here are the main actions that can result from an assignment notice:

  • Short call assignment: The option seller must sell shares of the underlying stock at the strike price.
  • Short put assignment: The option seller must buy shares of the underlying stock at the strike price.

For traders with long options positions, it's possible to choose to exercise the option, buying or selling according to the contract before it expires. With a long call exercise, shares of the underlying stock are bought at the strike price while a long put exercise results in selling shares of the underlying stock at the strike price.

When a trader might get assigned

There are two components to the price of an option: intrinsic 1 and extrinsic 2  value. In the case of exercising an in-the-money 3 (ITM) long call, a trader would buy the stock at the strike price, which is lower than its prevailing price. In the case of a long put that isn't being used as a hedge for a long stock position, the trader shorts the stock for a price higher than its prevailing price. A trader only captures an ITM option's intrinsic value if they sell the stock (after exercising a long call) or buy the stock (after exercising a long put) immediately upon exercise.

Without taking these actions, a trader takes on the risks associated with holding a long or short stock position. The question of whether a short option might be assigned depends on if there's a perceived benefit to a trader exercising a long option that another trader has short. One way to attempt to gauge if an option could be potentially assigned is to consider the associated dividend. An options seller might be more likely to get assigned on a short call for an upcoming ex-dividend if its time value is less than the dividend. It's more likely to get assigned holding a short put if the time value has mostly decayed or if the put is deep ITM and close to expiration with a wide bid/ask spread on the stock.

It's possible to view this information on the Trade page of the thinkorswim ® trading platform. Review past dividends, the price of the short call, and the price of the put at the call's strike price. While past performance cannot be relied upon to continue, this information can help a trader determine whether assignment is more or less likely.

Reducing the risk associated with assignment

If a trader has a covered call that's ITM and it's assigned, the trader will deliver the long stock out of their account to cover the assignment.

A trader with a call vertical spread 4 where both options are ITM and the ex-dividend date is approaching may want to exercise the long option component before the ex-dividend date to have long stock to deliver against the potential assignment of the short call. The trader could also close the ITM call vertical spread before the ex-dividend date. It might be cheaper to pay the fees to close the trade.

Another scenario is a call vertical spread where the ITM option is short and the out-of-the-money (OTM) option is long. In this case, the trader may consider closing the position or rolling it to a further expiration before the ex-dividend date. This move can possibly help the trader avoid having short stock on the ex-dividend date and being liable for the dividend.

Depending on the situation, a trader long an ITM call might decide it's better to close the trade ahead of the ex-dividend date. On the ex-dividend date, the price of the stock drops by the amount of the dividend. The drop in the stock price offsets what a trader would've earned on the dividend and there would still be fees on top of the price of the put.

Assess the risk

When an option is converted to stock through exercise or assignment, the position's risk profile changes. This change could increase the margin requirements, or subject a trader to a margin call, 5 or both. This can happen at or before expiration during early assignment. The exercise of a long option position can be more likely to trigger a margin call since naked short option trades typically carry substantial margin requirements.

Even with early exercise, a trader can still be assigned on a short option any time prior to the option's expiration.

1  The intrinsic value of an options contract is determined based on whether it's in the money if it were to be exercised immediately. It is a measure of the strike price as compared to the underlying security's market price. For a call option, the strike price should be lower than the underlying's market price to have intrinsic value. For a put option the strike price should be higher than underlying's market price to have intrinsic value.

2  The extrinsic value of an options contract is determined by factors other than the price of the underlying security, such as the dividend rate of the underlying, time remaining on the contract, and the volatility of the underlying. Sometimes it's referred to as the time value or premium value.

3  Describes an option with intrinsic value (not just time value). A call option is in the money (ITM) if the underlying asset's price is above the strike price. A put option is ITM if the underlying asset's price is below the strike price. For calls, it's any strike lower than the price of the underlying asset. For puts, it's any strike that's higher.

4  The simultaneous purchase of one call option and sale of another call option at a different strike price, in the same underlying, in the same expiration month.

5  A margin call is issued when the account value drops below the maintenance requirements on a security or securities due to a drop in the market value of a security or when buying power is exceeded. Margin calls may be met by depositing funds, selling stock, or depositing securities. A broker may forcibly liquidate all or part of the account without prior notice, regardless of intent to satisfy a margin call, in the interests of both parties.

Everything You Need to Know About Options Assignment Risk

early assignment of options

By Pat Crawley

The  fear of being assigned early on a short option position is enough to cripple many would-be options traders into sticking by their tried-and-true habit of simply buying puts or calls. After all, theoretically, the counterparty to your short options trade could exercise the option at any time, potentially triggering a Margin Call on your account if you’re undercapitalized.

But in this article, we're going to show you why early assignment is a vastly overblown fear, why it's not the end of the world, and what to do if it does occur.

What is Assignment in Options Trading?

Do you remember reading beginner  options books  or articles that said, "an option gives the buyer the right, but not the obligation, to buy/sell a stock at a specified price and date?" Well, it's accurate, but only for the buy side of the contract.

The seller of an option is actually obligated to buy or sell should the buyer choose to exercise their contract. So when options, assignment is when you, the lucky seller of an options contract, get chosen to make good on your obligation to buy or sell the underlying asset.

Let's say you sold a call option on a stock with a strike price of $50, which you held until expiration. At expiration, the stock trades at $55, meaning it's automatically exercised by the buyer. In this case, you are forced to sell the buyer 100 shares at $50 per share.

So when selling options, assignment is when you, the lucky seller of an options contract, get chosen to make good on your obligation to buy or sell the underlying asset.

What is Early Assignment in Options Trading?

Early assignment is when the buyer of an options contract that you're short decides to exercise the option before the expiration and begins the assignment process.

Many beginning traders count early assignments as one of their biggest trading fears. Many traders' fear of early assignment stems from their lack of understanding of the process. Still, it's typically not something to worry about, and we'll show you why in this article. But first, let's look at an example of how the process works.

For instance, say we collect $1 in premium to short a 30-day put option on XYZ with a strike price of $45 while the underlying is trading at $50. Fast forward, and it's the morning of expiration day. Options will expire at the close of trading in a few hours. The underlying stock is hovering around $44.85. Our plan pretty much worked as planned until, for some reason, the holder of the option exercises the option. We're confused and don't know what's going on.

It works exactly the same way as ordinary options settlement . You fulfill your end of the bargain. As the seller of a put option, you sold the right to sell XYZ at $45. The option buyer exercised that right and sold his shares to you at $45 per share.

And now, let's break down what happened in this transaction:

  • You collected $1 in premium when opening the contract  
  • The buyer of the option exercises his right to sell at $45 per share.  
  • You’re now long 100 shares of XYZ that you paid $45 for, and you sell them at the market price of $44.80 per share, realizing a $0.20 per share loss.  
  • Your profit on the transaction is $0.80 because you pocketed $1 from the initial sale of the option but lost $0.20 from selling the 100 shares from assignment at a loss.

Why Early Assignment is Nothing to Fear

Many beginning traders count early assignments as one of their biggest trading fears; on some level, it makes sense. As the seller of an option, you're accepting the burden of a legitimate obligation to your counterparty in exchange for a premium. You're giving up control, and the early assignment shoe can, on paper, drop at any time.

Exercising Options Early Burns Money

People rarely exercise options early because it simply doesn't make financial sense. By exercising an option, you're only capturing the option's intrinsic value and entirely forfeiting the extrinsic value to the option seller. There's seldom a reason to do this.

Let's put ourselves in the buyer's shoes. For instance, we pay $5 for a 30-day call with a strike price of $100 while the underlying is trading at $102. The call has $2 in intrinsic value, meaning our call is in-the-money by $2, which would be our profit if the option expired today.

The other $3 of the option price is extrinsic value. This is the value of time, volatility, and convexity. By exercising early, the buyer of an option is burning that $3 of extrinsic value just to lock in the $2 profit.

A much better alternative would be to sell the option and go and buy 100 shares of the stock in the open market.

Viewed in this light, an option seller can’t be blamed for looking at early assignment as a good thing, as they get to lock in their premium as profit.

Your Risk Doesn’t Change

One of the biggest worries about early assignment is that being assigned will somehow open the trader up to additional risk. For instance, if you’re assigned on a short call position, you’ll end up holding a short position in the underlying stock.

However, let me prove that the maximum risk in your positions stays the same due to early assignment.

How Early Assignment Doesn’t Change Your Position’s Maximum Risk

Perhaps you collect $2.00 in premium for shorting an ABC $50/$55 bear call spread. In other words, we're short the $50 call for a credit of $2.50 and long the $55 call, paying a debit of $0.50.

Before considering early assignment, let's determine our maximum risk on this call spread. The maximum risk for a bear call spread is the difference between the strike minus the net credit you receive. In this case, the difference between the strikes is $5, and we collect a net credit of $2, making our maximum risk on the position $3 or $300.

You wake up one morning with the underlying trading at $58 to find that the counterparty of your short $50 call has exercised its option, giving them the right to buy the underlying stock at $50 per share.

You'd end up short due to being forced to sell the buyer shares at $50. So you're short 100 shares of ABC with a cost basis of $50 per share. On that position, your P&L is -$800, the P&L on a $55 long call is +$250, on account of you paying $0.50, and the call being $3.00 in-the-money. And finally, because the option holder exercised early, you get to keep the entire credit you collected to sell the $50 call, so you've collected +$250.

So your P&L is $300. You've reached your max loss. Let's get extreme here. Suppose the price of the underlying runs to $100. Here are the P&Ls for each leg of the trade:

  • Short stock: -$5,000  
  • Long call: +$4,450  
  • Net credit received from exercised short option: +$250  
  • 5,000 - (4,450 + 250) = $300

While dealing with early assignments might be a hassle, it doesn’t open a trader up to additional risk they didn’t sign up for.

Margin Calls Usually Aren’t The End of the World

Getting a margin call due to early assignment isn't the end of the world. Believe it or not, stock brokerages have been around for a long time. They have seen early assignments many times before, and they have protocols for it.

Think about it intuitively, your broker allowed you to open the short option position knowing that the capital in your account could not cover an early assignment. Still, they let you make the trade anyways.

So what happens when you get an early assignment that you can’t cover? Your broker issues you a margin call. Once you’re in violation of their margin rules, they pretty much have carte blanche to handle the situation as they wish, including liquidating the assigned stock position at their will.

However, most brokers will give you some time to react to the situation and either decide to deposit more capital, liquidate the position on your own, or exercise offsetting options to fulfill the margin call in the case of an option spread.

Even though a margin call isn't fun, remember that the overall risk of your position doesn't change due to an early assignment, and it's typically not a momentous event to deal with. You probably just have to liquidate the trade.

When Early Assignment Might Occur?

Dividend Capture

One of the few times it might make sense for a trader to exercise an option early is when he's holding a call that is deep in-the-money, and there's an upcoming ex-dividend date.

Because deep ITM calls have very little extrinsic value (because their deltas are so high), any negligible extrinsic value is often outweighed by the value of an upcoming dividend payment , so it makes sense to exercise and collect the dividend.

Deep In-The-Money Options Near Expiration

While it's important to emphasize that the risk of early assignment is very low in most cases, the likelihood does rise when you're dealing with options with very little extrinsic value, like deep-in-the-money options. Although, even in those cases, the probabilities are pretty low.

However, an options trader that is trading to exploit market anomalies like the volatility risk premium, in which implied volatility tends to be overpriced, shouldn't even be trading deep-in-the-money options anyhow. Profitable option sellers tend to sell options with very little intrinsic value and tons of extrinsic value.

Bottom Line

Don't let the  fear of early assignment discourage you from selling options. Far worse things when shorting options! While it's true that early assignment can occur, it's typically not a big deal. Related articles

You’ll often read that a given option trade is either vega positive (meaning that IV rising will help it and IV falling will hurt it) or vega negative (meaning IV falling will help and IV rising will hurt).   However, in fact many popular options spreads can be either vega positive or vega negative depending where where the stock price is relative to the spread strikes.

How dividends can increase options assignment risk

early assignment of options

Most experienced investors are familiar with the adage that "if an investment opportunity sound too good to be true, it probably is." While this sentiment may often be associated with overly optimistic assumptions, it also applies to investors who sell options contracts without first considering the ex-dividend date for a stock or ETF.

How dividends work

A quick review of how dividends work: A dividend represents a payment of a company's revenues to shareholders, most often in the form of cash. Cash dividends are paid out on a per-share basis. For example, if you own 100 shares of a stock that pays a $0.50 quarterly dividend, you will receive $50.

Not all companies pay dividends, but if you're investing in options contracts for companies that do pay them, you need to keep several important dates in mind:

  • Declaration date: Date on which a company announces the per-share amount of its next dividend.
  • Record date: The cut-off date established by the company to determine which shareholders of its stock are eligible to receive a distribution. This is usually, but not always, 1 day after the ex-dividend date.
  • Ex-Dividend date: Date on which a stock's price adjusts downward to reflect its next dividend payment. For example, if a stock pays a $0.50 dividend, the stock price will drop by a half point prior to trading on the ex-dividend date. If you buy a stock on or after the ex-dividend date, you are not entitled to the next dividend.
  • Dividend (payment) date: Date shareholders receive cash in their account from a dividend.

See Locating dividend information for stocks for additional details.

Dividends offer an effective way to earn income from your equity investments. However, call option holders are not entitled to regular quarterly dividends, regardless of when they purchase their options. And, unlike stock or ETF prices, options contract prices are not adjusted downward on ex-dividend dates.

This can cause a problem for anyone who has sold an options contract without first considering the impact of dividends. Why? Because the risk of being assigned on an option contract is higher when the underlying security of an in-the-money option starts trading ex-dividend. To understand the risks and how dividends impact options contracts, let's explore some potential scenarios.

Avoiding or managing early assignment on covered calls

As noted above, the ex-dividend date is particularly important to anyone who writes a covered or uncovered call option. If a covered call option you have sold is in the money and the dividend exceeds the remaining time value of the option, there is a good chance an owner of those calls will exercise his options early.

If you are assigned, you must deliver your shares of the underlying security, as well as the dividend income, to the owner of the call. Let's examine a hypothetical example to illustrate how this works.

  • Bob owns 500 shares of ABC stock, which pays a quarterly $0.50 dividend.
  • The stock is trading around $25 a share on August 1 when Bob decides to sell 5 October 30 calls.
  • By early October, ABC stock has risen to $31 and, as a result, Bob's covered calls are in the money by $1. The calls will expire in 10 days and tomorrow the stock will start trading ex-dividend.
  • Because the remaining time value of the call option is less than the value of the dividends, the call owner will likely exercise his options on the day before the ex-dividend date.

See Locating option values in Active Trader Pro ® .

If Bob does not take any action to close his covered call position, there is a good chance he will be assigned on the ex-dividend date. This means he will no longer own 500 shares of the stock and he will not receive the dividend income.

To avoid this scenario, Bob has a couple of choices:

  • He could buy back the calls he sold to retain the stock and the dividend. However, he would have to do this prior to the ex-dividend date. If he waits until the ex-dividend date or later, he will not be entitled to the dividend income. Keep in mind that it's possible to get assigned prior to the day before the ex-dividend date, so this strategy is not foolproof.
  • The other option is to close out his short position and write a new covered call with a later expiration date or a higher strike price. This strategy is known as "rolling" your options contract forward.

Avoiding or managing early assignment on calls not covered by shares

Now let's consider what could happen if Bob had sold uncovered calls on ABC stock:

  • As in the example above, ABC stock pays a quarterly $0.50 dividend and is trading around $25 a share
  • Bob has a negative view on the stock and decides to sell 5 uncovered October 30 calls
  • By early October, ABC stock has risen to $31 and, as a result, his uncovered calls are in the money by $1

To make matters worse, Bob learns that tomorrow the stock will start trading ex-dividend. Because the remaining time value of the options is less than the value of the dividends, owners of these calls will likely exercise their options 1 day prior to the ex-dividend date.

To limit his exposure, Bob has several choices. He can buy back his uncovered calls at a loss, buy the stock to capture the dividend, or sit tight and hope to not be assigned. If his calls are assigned, however, he will have to pay the $250 in dividend income, in addition to covering the cost of delivering 500 shares of ABC stock. If Bob had initiated an option spread (buying and selling an equal number of options of the same class on the same underlying security but with different strike prices or expiration dates), he could also consider exercising his long option position to capture the dividend.

Other considerations and risks

If you are implementing a spread strategy that includes long contracts and short contracts, you need to remain particularly vigilant in regard to assignment risk. If both contracts are in the money and you are assigned on the short contracts, you will not be notified until the following business day. While you can exercise your long position on the ex-dividend date to eliminate the short stock position that was created, you will still owe the dividend because you were short the stock prior to the ex-dividend date.

Ways to avoid the risk of early assignment

If you are selling options (covered or uncovered), there is always the risk of being assigned if your trade moves against you. This risk is higher if the underlying security involved pays a dividend. However, there are ways to reduce the likelihood of being assigned early. These include:

  • Do your homework: Know if the stock or ETF pays a dividend and when it will start trading ex-dividend
  • Avoid selling options on dividend-paying stocks or ETFs when your trade includes ex-dividend
  • Invest in European-style options: American-style options can be assigned at any time before the option expires, European-style options can only be exercised at expiration

See Locating dividend information for ETFs for details.

MODULE 9 – HOW TO DEAL WITH EARLY ASSIGNMENT

First it is important to note that early Assignment is only an issue for American style options.

If you are trading Iron Condors on the indexes (RUT, SPX, NDX and MNX), you do not even need to worry about early assignment.

These are European Options and are cash settled. Contrastingly for ETF’s (IWM, SPY and QQQ) and single stock options there is a risk of early assignment.

Despite this in this module we will explain the risk of early assignment is almost inconsequential.

In fact, assignment when it happens can be an exceptionally good thing.

The reason why American options are almost never exercised before expiration is to do with the characteristics of an option itself.

An option has two sources of value, intrinsic and extrinsic value. Intrinsic value is the value of the option if it is exercised today, extrinsic value is the time value of the option.

The important thing about an option is that the extrinsic or time value must be equal or greater than 0.

Thus, exercising options voluntarily removes the extrinsic value for the buyer.

There are few reasons options are exercised before expiration because of this.

Generally, options could potentially be exercised early when they are deep ITM and have almost no extrinsic value left.

This can sometimes happen with dividends if an investor would prefer to exercise and receive the dividend as opposed to continue to hold the call on a deep ITM option.

Another reason might be if a large institution had an exceptionally large position, it might be cheaper to exercise early than to sell the position in the options market and pay the bid / ask spread on a less liquid underlying.

A deep ITM option can sometimes also be exercised if the borrowing rate becomes attractive.

All these are rare and even more rare is an option exercised with a lot of extrinsic value left. If this happens you won the lottery.

Despite this, depending how margin is calculated at your brokerage you may be left with a margin call.

In this case simply sell or buy back the assigned shares and sell back the other leg of the option.

The other main assignment risk, which happens more often occurs on expiration day.

This occurs when a options short leg is exactly At The Money. In this case it can become unclear whether assignment will occur.

As American Options trade after hours on Friday this can sometimes lead to some surprise assignments come Monday morning.

In this case the best way to avoid the risk of assignment is to simply close out the position on the day of expiry.

Traders that want to learn more about options assignment and exercise, should read this article.

In the 10th and final Module in the iron condor course, we will be looking at whether we should trade iron condors on indexes or ETF’s.

Trading OEX Options: The Risk of Early Exercise

early assignment of options

A popular strategy among options investors is covered call writing: the investor buys 100 shares of stock and sells one call option , granting someone else the right to buy that stock at a specific price, known as the strike price , for a limited time. Often, the option expires worthless and the investor keeps both the stock and the option premium.

However, sometimes the option owner exercises the option. That means the investor is assigned an exercise notice and is obligated to sell the stock. This achieves the maximum profit available when writing covered calls.

Many investors fear being assigned that exercise notice. They may believe someone has cheated them because the stock is trading above the strike price. In fact, being assigned early can benefit option investors, except in one case: OEX options. OEX, which trades on the  Chicago Board Options Exchange  (CBOE), is the ticker symbol used to identify Standard & Poor's 100 index options.

  • OEX options get their name from the ticker symbol of the Standard & Poor's 100 stock index.
  • OEX options have a particular risk to the investor if they are assigned early.
  • The risk can be mitigated by the investor.

How an Early Exercise Works

Here's the hard truth: Being assigned an exercise notice is nothing more than a notification that you fulfilled the obligation you previously accepted when selling the option contract. If you own stock that you don't want to sell under any circumstances, then you shouldn't be writing covered calls.

If you trade spreads (buy one option and sell another), then being assigned an exercise notice does not adversely affect your overall position. You lose nothing.

In fact, assuming your account has sufficient margin to carry the position, receiving an assignment notice before expiration can turn into free money on occasion because of the additional profit potential. In other words, if the stock suddenly drops below the strike price, every penny of that decline below the strike is extra cash in your pocket - cash that you couldn't earn if you were short the call instead of stock.

The OEX Exception

The above is a rather lengthy explanation of why being assigned an exercise notice should (almost) never be a concern. As mentioned above, there is one important exception, and that occurs when you sell OEX options.

These options are cash-settled , American-style options. All other actively traded index options are European-style and cannot be exercised prior to expiration.

Why is OEX an exception? And what's the big deal about being assigned an exercise notice before expiration arrives anyway? Didn't we just learn that an investor shouldn't fear early assignment?

When using equity options, if you are assigned on a call, the option is canceled and, instead, you become short 100 shares of stock (or you lose 100 shares of stock that you own). As such, your upside risk is unchanged, but your potential downside profit is increased.

Everything changes, however, when you are assigned early and the option is cash-settled. Let's take a look at why this happens:

  • When assigned on a cash-settled OEX option, you are obligated to repurchase the option at last night's intrinsic value . (We'll take a look at how this works in the example below.)
  • You don't learn that you have been assigned until the following morning before the market opens for trading.
  • Your position changes. You are no longer short the option because you were forced to buy it—with no advance notice.
  • When trading equity options, the call option you were short is replaced with short stock. Upon assignment, a short put position is replaced with long stock. But, when assigned on a cash-settled option, the option position is canceled and there is no replacement.
  • This assignment notice often occurs as a surprise to the option rookie, who not only doesn't understand why anyone would exercise the option before expiration, but also probably doesn't know that early exercise is possible.

Protecting Yourself From Early Exercise

Here's how you can avoid this OEX options pitfall.

Example 1: Losses on an OEX Put Spread

Let's say you decide to take a bullish position and sell an OEX put spread (which makes money when OEX remains above the strike price of the option sold). Assume OEX is currently 560.

Example 2: The Effects of an Exercise Notice

Let's consider a different scenario. Let's assume that late one afternoon, about two weeks prior to June expiration, OEX is trading at 500. That's not good because there's a high probability that both options will be in the money when expiration arrives, forcing you to take the maximum loss.

But there's hope! About two minutes after the stock market closes for trading (index options continue trading for another 15 minutes), the U.S. Federal Reserve unexpectedly announces an interest rate cut of 50 basis points (0.5%).

The announcement takes everyone by surprise. Stocks have stopped trading for the day on the NYSE, but after-hours trading is taking place and stock prices are higher. Stock index futures soar, indicating that the market is expected to open much higher tomorrow.

The OEX calls increase in price as everyone wants to buy. Similarly, puts are offered at lower prices. The bid/ask prices for the options change, but the OEX has an official closing price of $540. The index price ignores after-hours trading.

The OEX Jun 540 puts (your short option) was $40 before the news, but now the bid has dropped to $28. No one will sell that option at that price.

Why? Anyone who owns the put can exercise it and receive the option's intrinsic value (strike price minus OEX price), or $40.

When you get home from work and hear the news about interest rates, you are elated. What a lucky break for you! If the rally continues and OEX moves above 540, you will earn a profit from this position.

The Next Day…

You eagerly open your computer the following morning. Sure enough, the DJIA futures are 250 points higher. But, when you look at your online brokerage account you notice something unusual. Your OEX position shows that you are long 10 Jun OEX 530 puts, but there is no position in the Jun 540 puts. You don't understand and immediately call your broker.

The customer service rep tells you to look at your transactions for yesterday. You know you didn't make any trades, but there it is—right in front of you: You bought 10 Jun OEX 540 puts @ $40.

You carefully explain that there must be some mistake because you didn't make the trade. That's when the rep tells you that you were assigned an exercise notice that obligated you to repurchase those options at last night's intrinsic value. With the OEX closing price of 500, you must pay $40 for each option. The customer service rep tells you they're sorry but nothing can be done and asks why you failed to exercise your Jun 530 puts when the news was released. But perhaps you didn't know you could do that.

Your spread is gone. All you have left is 10 Jun OEX 530 puts. When the market opens and OEX is 515. There's no reason to gamble by holding the puts, so you unhappily sell the OEX Jun 530 puts, collecting $15 for each. You thought your maximum loss for the trade was $750 per spread, but you paid $25 to close the spread (pay 40, sell at 15) and thus lost $2,250 per spread ($2,500 to close the position minus the amount you collected for the spread at the beginning, which in this case was $250 per spread), or $22,500 when you account for the entire position of ten contracts. Ouch!

It's too late to do anything in the imaginary scenario above, but now that you understand the problem, there are two good alternatives:

  • Don't sell OEX options.
  • Trade one of the other indexes that are cash-settled, European style.

In these cases, you cannot be assigned an exercise notice prior to expiration and this unhappy event won't ever happen to you.

Managing Early Assignment in the Options Market

Assignment, particularly early assignment, is a topic that can give many would-be options traders a pause. It’s also one that can cause quite a panic if you’re unprepared and unsure how to respond.

I know what it was like when I first started trading options and how afraid I was at the possibility of getting assigned. I also remember all too clearly the various instances of getting assigned and how big of a fright it gave me! This was particularly true when trading with a much smaller account, and I inevitably would end up with a margin call due to assignment. This occurs when you get assigned more stock than your account can handle.

You may say, “Margin call?!” What?! Generally (as long as you are trading a defined risk strategy and/or you exit your shares), you can get out of your shares, and that will remove the margin call. I have never had a situation where I had to deposit money to get out of a margin call, but it can happen if you trade options naked or don’t control your risk.

Now, it all sounds scary, but I can tell you that as long as you understand the basics of how options work, your rights and obligations, and how to manage in the event of an assignment, it is more of an annoyance than anything. And, in fact, I would say more often than not recently, being assigned has worked out to my benefit. I am still holding 20 shares of Microsoft after I was assigned at $285 (and Microsoft is currently trading at around $344).

Making Money on Assignment

There was also a time when I got assigned Facebook shares, didn’t realize, and went on vacation for a week. I had thought my options trade was expiring out of the money on a Friday, but it ticked up at the very end of the day, and my option expired just slightly in the money. I was leaving for a trip with my family, and I had promised my son I would not be working and would not even open my laptop! A week later, I opened my trading platform to discover that not only had I been assigned but that Facebook shares had skyrocketed, and I accidentally made $1,700 when I was on vacation. That was also during a time frame when I was trading super small and attempting to make $50-100 a day, so $1700 was a huge win for me! So, it’s not always the worst thing that can happen!

All of this being said every assignment is different. It depends on your account size, what other trades you’re holding, if you want the shares or not, and what your overall strategy is.

early assignment of options

Types of Assignments I’ve Experienced

For example, I have dealt with assignments on purpose and accidentally in a variety of ways, such as:

  • I have sold puts on purpose just to get assigned stock at a lower price and collect premium (this was a great strategy on DWAC for a while)
  • I have bought stock and sold calls against it just to collect premium without worrying about losing the shares as they were bought for this purpose.
  • I have had bullish earnings trades go against me and gotten assigned on the short puts, then waded my way out using the stock to make back the money lost on the trade.
  • I have gotten assigned and exercised the other leg of my option to get out using the same risk parameters I used originally (as noted in the video below).
  • I have gotten assigned on a Friday and lost my protection, and ended up with shares I either kept or had to buy my way out of.

So, as you can see, there are many different ways to use assignment (or have it used against you), but the most important thing to understand is

  • Having protection for any option you sell will define your risk and protect you by locking in your risk parameters in the instance you experience early assignment
  • Not paying attention to your trades and letting them expire in the money on a Friday is an almost surefire way to get assigned
  • When half of your options strategy is in the money, and the other half isn’t at a Friday expiration, the short and the long will not cancel each other out, and you can get assigned
  • Control your risk from the get-go, pay attention to your trades, and ask support in your platform if you aren’t sure what to do!

Now, I’m happy to discuss what I’ve been through and how I have managed it, but please keep in mind I can’t give you advice on what you should do in your own account.

Tesla – An Assignment On a Losing Position

All of that being said, check out this video I made last week when I was assigned early on Tesla after a failed TSLA earnings trade. In this situation, I did not want to hold the shares. I hold my Tesla shares in my long-term investing accounts and don’t want more in my trading account. I also didn’t want them because I was assigned at $295, and Tesla was trading around $265. Keeping the shares would have meant having potentially massive downside risk. At the time, I still had a put at $275, so I could get out of my Tesla shares with the same defined risk I used to get into my earnings trade. Could I have just sold the put on Friday, kept the money, and then kept the shares, hoping TSLA went higher, attempting to make back money on my losing trade? Yes, I could have done that, but it is VERY risky, so I did not want to.

Learn more in the video below:

People also ask…well, you lost money on your Tesla trade. So, are you going to try and make that back? Trying to return to a ticker and ‘make back the money you lost,’ is almost always a bad idea. I will trade TSLA again when another setup appears. I did make back some of the money I lost on Friday by buying Walmart when money rotated into it and buying hedges in the QQQs. I haven’t closed my WMT yet, but I made a good chunk of that. So, I’m not too worried about it. And I was able to use this experience to help others. So, all is not lost!

What is Options Assignment & How to Avoid It

options assignment explained

If you are learning about options, assignment might seem like a scary topic. In this article, you will learn why it really isn’t. I will break down the entire options assignment process step by step and show you when you might be assigned, how to minimize the risk of being assigned, and what to do if you are assigned.

Video Breakdown of Options Assignment

Check out the following video in which I explain everything you need to know about assignment:

What is Assignment?

To understand assignment, we must first remember what options allow you to do. So let’s start with a brief recap:

  • A call option gives its buyer the right to buy 100 shares of the underlying at the strike price
  • A put option gives its buyer the right to sell 100 shares of the underlying at the strike price

In other words, call options allow you to call away shares of the underlying from someone else, whereas a put option allows you to put shares in someone else’s account. Hence the name call and put option.

The assignment process is the selection of the other party of this transaction. So the person that has to buy from or sell to the option buyer that exercised their option.

Note that an option buyer has the right to exercise their option. It is not an obligation and therefore, a buyer of an option can never be assigned. Only option sellers can ever be get assigned since they agree to fulfill this obligation when they sell an option.

Let’s go through a specific example to clarify this:

  • The underlying security is stock ABC and it is trading at $100.
  • Peter decides to buy 1 put option with a strike price of 95 as a hedge for his long stock position in ABC
  • Kate sells this exact same option at the same time.

Over the next few weeks, ABC’s price goes down to $90 and Peter decides to exercise his put option. This means that he uses his right to sell 100 shares of ABC for $95 per share. Now Kate is assigned these 100 shares of ABC which means she is obligated to buy them for $95 per share. 

options exercise and assignment

Peter now has 100 fewer shares of ABC in his portfolio, whereas Kate has 100 more.

This process is analog for a call option with the only difference being that Kate would be short 100 shares and Peter would have 100 additional shares of ABC in his portfolio.

Hopefully, this example clarifies what assignment is.

Who Can Be Assigned?

To answer this question, we must first ask ourselves who exercises their option? To do this, let’s quickly look at the different ways that you can close a long option position:

  • Sell the option: Selling an option is probably the easiest way to close a long option position. Doing this will have no effect on the option seller.
  • Let the option expire: If the option is Out of The Money , it would expire worthless and there would be no consequence for the option seller. If, on the other hand, the option is In The Money by more than $0.01, it would typically be automatically exercised . This would start the options assignment process.
  • Exercise the option early: The last possibility would be to exercise the option before its expiration date. This, however, can only be done if the option is an American-style option. This would, once again, lead to an option assignment.

So as an option seller, you only have to worry about the last two possibilities in which the buyer’s option is exercised. 

options assignment statistic

But before you worry too much, here is a quick fact about the distribution of these 3 alternatives:

Less than 10% of all options are exercised.

This means 90% of all options are either sold prior to the expiration date or expire worthless. So always remember this statistic before breaking your head over the risk of being assigned.

It is very easy to avoid the first case of being assigned. To avoid it, just close your short option positions before they expire (ITM). For the second case, however, things aren’t as straight forward.

Who Risks being Assigned Early?

Firstly, you have to be trading American-style options. European-style options can only be exercised on their expiration date. But most equity options are American-style anyway. So unless you are trading index options or other kinds of European-style options, this will be the case for you.

Secondly, you need to be an options seller. Option buyers can’t be assigned.

These two are necessary conditions for you to be assigned. Everyone who fulfills both of these conditions risks getting assigned early. The size of this risk, however, varies depending on your position. Here are a few things that can dramatically increase your assignment risk:

  • ITM: If your option is ITM, the chance of being assigned is much higher than if it isn’t. From the standpoint of an option buyer, it does not make sense to exercise an option that isn’t ITM because this would lead to a loss. Nevertheless, it is possible. The deeper ITM the option is, the higher the assignment risk becomes.
  • Dividends : Besides that, selling options on securities with upcoming dividends also increases your risk of assignment. More specifically, if the extrinsic value of an ITM call option is less than the amount of the dividend, option buyers can achieve a profit by exercising their option before the ex-dividend date. 
  • Extrinsic Value: Otherwise, keep an eye on the extrinsic value of your option. If the option has extrinsic value left, it doesn’t make sense for the option buyer to exercise their option because they would achieve a higher profit if they just sold the option and then bought or sold shares of the underlying asset. Typically, the less time an option has left, the lower its extrinsic value becomes. Implied volatility is another factor that influences extrinsic value.
  • Puts vs Calls: This is more of an interesting side note than actual advice, but put options tend to get exercised more often than call options. This makes sense since put options give their buyer the right to sell the underlying asset and can, therefore, be a very useful hedge for long stock positions.

How can you Minimize Assignment Risk?

Since you now know what assignment is, and who risks being assigned, let’s shift our focus on how to minimize the assignment risk. Even though it isn’t possible to completely remove the risk of being assigned, there are things that you can do to dramatically decrease the chances of being assigned.

The first thing would be to avoid selling options on securities with upcoming dividend payments. Before putting on a position, simply check if the underlying security has any upcoming dividend payments. If so, look for a different trade.

If you ever are in the position that you are short an option and the ex-dividend of the underlying security is right around the corner, compare the size of the dividend to the extrinsic value of your option. If the extrinsic value is less than the dividend amount, you really should consider closing the position. Otherwise, the chances of being assigned are high. This is especially bad since being short during a dividend payment of a security will force you to pay the dividend.

Besides avoiding dividends, you should also close your option positions early. The less time an option has left, the lower its extrinsic value becomes and the more it makes sense for option buyers to exercise their options. Therefore, it is good practice to close your (ITM) short option positions at least one week before the expiration date.

The deeper an option is ITM, the higher the chances of assignment become. So the just-mentioned rule is even more important for deep ITM options.

If you don’t want to indefinitely close your position, it is also possible to roll it out to a later expiration cycle. This will give you more time and add extrinsic value to your position.

FAQs about Assignment

Last but not least, I want to answer some frequently asked questions about options exercise and assignment.

1. What happens if your account does not have enough buying power to cover the assigned position?

This is a common worry for beginning options traders. But don’t worry, if you don’t have enough capital to cover the new position, you will receive a margin call and usually, your broker will just automatically close the assigned shares immediately. This might lead to a minor assignment fee, but otherwise, it won’t significantly affect your account. Tatsyworks, for example, charges an assignment fee of only $5.

Check out my review of tastyworks

2. How does assignment affect your P&L?

When an option is exercised, the option holder gains the difference between the strike price and the price of the underlying asset. If the option is ITM, this is exactly the intrinsic value of the option. This means that the option holder loses the extrinsic value when he exercises his/her option. That’s also why it doesn’t make sense to exercise options with a lot of extrinsic value left.

options assignment extrinsic value

This means that as soon as the option is exercised, it is only the intrinsic value that is relevant for the payoff. This is the same payoff as the option at its expiration date.

So as an options seller, your P&L isn’t negatively affected by an assignment. Either it stays the same or it becomes slightly better due to the extrinsic value being ignored.

As an example, if your option is ITM by $1, you will lose up to $100 per option or $1 per share that you are assigned. But this does not account for the extrinsic value that falls away with the exercise of the option. So this would be the same P&L as at expiration. Depending on how much premium you collected when selling the option, this might still be a profit or a minor loss.

With that being said, as soon as you are assigned, you will have some carrying risk. If you don’t or can’t close the position immediately, you will be exposed to the ongoing price fluctuations of that security.  Sometimes, you might not be able to close the new position immediately because of trading halts, or because the market is closed.

If you weren’t planning on holding that security, it is a good idea to close the new position as soon as possible. 

Option spreads such as vertical spreads, add protection to these price fluctuations since you can just exercise the long option to close the assigned share position at the strike price of the long option.

3. When an option holder exercises their option, how is the assignment partner chosen?

random options assignment process

This is usually a random process. As soon as an option is exercised, the responsible brokerage firm sends a request to the Options Clearing Corporation (OCC). They send back the requested shares, whereafter they randomly choose another brokerage firm that currently has a client that is short the exercised option. Then the chosen broker has to decide which of their clients is assigned. This choice is, once again, random or a time-based priority system is used.

4. How does assignment work for index options?

As there aren’t any shares of indexes, you can’t directly be assigned any shares of the underlying asset. Therefore, index options are cash-settled. This means that instead of having to buy or sell shares of the underlying, you simply have to pay the difference between the strike price and the underlying trading price. This makes assignment easier and a lot less likely among index options.

Note that ETF options such as SPY options are not cash-settled. SPY is a normal security with openly traded shares, so exercise and assignment work just like they do among equity options.

options assignment dont panic

I hope this article made you realize that assignment isn’t as bad as it might seem at first. It is just important to understand how the options assignment process works and what affects the likelihood of being assigned.

To recap, here’s what you should to do when you are assigned:

if you have enough capital in your account to cover the position, you could either treat the new position as a normal (stock) position and hold on to it or you could close it immediately. If you don’t have a clear trading plan for the new position, I recommend the latter.

If, on the other hand, you don’t have enough buying power, you will receive a margin call from your broker and the position should be closed automatically.

Assignment does not have any significant impact on your P&L, but it comes with some carrying risk. Options spreads can offer more protection against this than naked option positions.

To mitigate assignment risk, you should close option positions early, always keep an eye on the extrinsic value of your option positions, and avoid upcoming dividend securities.

And always remember, less than 10% of options are exercised, so assignment really doesn’t happen that often, especially not if you are actively trying to avoid it.

For the specifics of how assignment is handled, it is a good idea to contact your broker, as the procedures can vary from broker to broker.

hi there well seems like finally there is one good honest place. seem like you are puting on the table the whole truth about bad positions. however my wuestion is when can one know where to put that line of limit. when do you recognise or understand that you are in a bad position? thanks and once again, a great site.

Well If you are trading a risk defined strategy the point would be at max loss and not too much time left until expiration. For undefined risk strategies however it can be very different. I would just say if you don’t have too much time until expiration and are far from making money you should use some common sense and admit that you are wrong.

What would happen in the event of a crash. Would brokers be assigning, options, cashing out these shares, and making others bankrupt. Well, I guessed I sort of answered my own question. Its not easy to understand, especially not knowing when this would come up. But seems like you hit the important aspects of the agreement.

Actually I wouldn’t imagine that too many people would want to exercise their options in case of a market ctash, because they probably wouldn’t want to hold stocks in this risky and volatile environment. 

And to the part of the questions: making others bankrupt. This really depends on the situation. You can’t get assigned more stock than your option covers. This means as long as you trade with reasonable position sizing nothing too bad can happen. Otherwise I would recommend to trade with defined risk strategies so your maximum drawdown is capped.

Thanks for writing about assignment Louis. After reading the section how assignment works, I feel I am somewhat unclear about how assignment works when the exerciser exercises Put or Call option. In both cases, if the underlying is an index, is the settlement done through the margin account money? Would you be able to provide a little more detail of how exercising the option (Put vs Call) would work in case of an underlying stock vs Index.

Thank you very much in advance

Thanks for the question. Indexes can’t be traded in the same way as stocks can. That’s why index options are settled in cash. If your index option is assigned, you won’t have to buy or sell any shares of the underlying index at the strike price because there exist no shares of indexes. Instead, you have to pay the amount that your index option is ITM to the exerciser of your option. Let me give you an example: You are short a call option with the strike price of 1000. The underlying asset is an index and it’s price is 1050. This means your call option is 50 points ITM. If someone exercises your long call option, you will have to pay him/her the difference between the strike price and the underlying’s price which would be 50 (1050-1000). So the main difference between index and stock options is that you don’t have to buy/sell any shares of the underlying asset for index options. I hope this helps. Please let me know if you have any other questions or comments.

Can the same logic be applied for ETFs as it does Indexes? For example, if I trade the SPY ETF, would it be settled in cash?

Thanks! Johnson

Hi Johnson, Exercise and assignment for ETFs such as SPY work just like they do for equities. ETFs have shares that are openly traded, whereas indexes don’t. That’s why indexes are settled in cash, whereas ETFs aren’t. I hope this helps.

There are many articles online that I read that are biased against options tradings and I am a bit surprised to read a really helpful article like this. I find this helpful in understanding options trading, what are the techniques and how to manage the risks. Before, I was hesitant to try this financial game but now, after reading this article, I am considering participating with live accounts and no longer with a demo account. A few months ago, I signed up with a company called IQ Options, but really never involved real money and practiced only with a demo account.

Thanks for your comment. I am glad to see that you liked the post. However, I don’t recommend sing IQ Option to trade since they are a very shady trading firm. You could check out my  Review of IQ Option for all the details.

this is a great and amazing article. i sincerely your effort creating time  to write on such an informative article which has taught me a lot more on what is options assignment and avoiding it. i just started trading but had no ideas on this as a beginner. i find this article very helpful because it has given me more understanding on options trading and knowing the techniques and how to manage the risks. thanks for sharing this amazing article

You are very welcome

Hello, the first thing that i noticed when i opened this page is the beauty of the website. i am sure you have put much effort into creating this article and the details are really clear here. after watching the video break down, i fully understood the entire process on how to avoid options assignment.

Thank you so much for the positive feedback!

I would love to create a website like yours as the design used is really nice, simple and brings about clarity of the write ups, but then you wrote a brilliant article on how to avoid options assignment. great video here. it was  confusing at first. i will suggest another video be added to help some people like me.

Thanks for the feedback. I recommend checking out my  options trading beginner course . In it, I cover all the basics that weren’t explained here.

Thanks for your very helpful article. I am contemplating selling a call that would cover half my shares on company X. How can ensure that the assignment process selects the shares that I bought at a higher price, so as to maximize capital losses?

Hi Luis, When you are assigned, you just automatically buy/sell shares of the underlying at the strike price. This means your overall portfolio is adjusted by these 100 shares. The exact shares and your entry price are irrelevant. If you have 50 shares of X and your short call is assigned, you will sell 100 shares of X at the strike price. After this, your position would be -50 shares of X which would be equivalent to being short 50 shares of X. I hope this helps.

Louis, I entered a CALL butterfly spread at $100 below where I intended, just 2 days before expiration date. I intended to speculate on a big earning announcement jump the next day. It was a debit of 1.25. Also, when I realized my mistake, I tried to close it for anything at all. The Mark fluctuated between 40 and 70, but I could not get it to close. So now I am assigned to sell 200 share at 70 dollars below the market price of the stock. I am having a heart attack. I do not have the 200 shares to deliver, so it seems I have to buy them at the market, and sell them for $70 less, for a loss of $14,000.

What other options are open to me? Can my trading firm force a close with a friendly market maker and make it as if it happened on Friday? I am willing to pay a friendly market maker several hundred dollars to make this trade. Is that an option? Other options the trading firm can do for me that would cost me less than $14,000?

Hi Paul, Thanks for your comment. From the limited information provided, it is hard to say what is actually going on. If you bought a call butterfly spread, your max loss should be limited to the premium you paid to open the position. An assignment shouldn’t have a huge impact on your overall P&L. I highly recommend contacting your broker and explaining your situation to them since they have all the information required to evaluate what’s actually going on. But if the loss is real, there is no way for you to make a deal with a market maker to limit or undo potential losses. I hope this helps.

What happens with ITM long call option that typically gets automatically exercised at expiration, if the owner of the call option doesn’t have the cash/margin to cover the stock purchase?

He would receive a margin call

Everything You Need to Know About Options Assignment Risk

John Doe

But in this article, we’re going to show you why early assignment is a vastly overblown fear, why it’s not the end of the world, and what to do if it does occur.

What is Assignment in Options Trading?

Do you remember reading beginner  options books  or articles that said, “an option gives the buyer the right, but not the obligation, to buy/sell a stock at a specified price and date?” Well, it’s accurate, but only for the buy side of the contract.

The seller of an option is actually obligated to buy or sell should the buyer choose to exercise their contract. So when options, assignment is when you, the lucky seller of an options contract, get chosen to make good on your obligation to buy or sell the underlying asset.

Let’s say you sold a call option on a stock with a strike price of $50, which you held until expiration. At expiration, the stock trades at $55, meaning it’s automatically exercised by the buyer. In this case, you are forced to sell the buyer 100 shares at $50 per share.

So when selling options, assignment is when you, the lucky seller of an options contract, get chosen to make good on your obligation to buy or sell the underlying asset.

What is Early Assignment in Options Trading?

Early assignment is when the buyer of an options contract that you’re short decides to exercise the option before the expiration and begins the assignment process.

Many beginning traders count early assignments as one of their biggest trading fears. Many traders’ fear of early assignment stems from their lack of understanding of the process. Still, it’s typically not something to worry about, and we’ll show you why in this article. But first, let’s look at an example of how the process works.

For instance, say we collect $1 in premium to short a 30-day put option on XYZ with a strike price of $45 while the underlying is trading at $50. Fast forward, and it’s the morning of expiration day. Options will expire at the close of trading in a few hours. The underlying stock is hovering around $44.85. Our plan pretty much worked as planned until, for some reason, the holder of the option exercises the option. We’re confused and don’t know what’s going on.

It works exactly the same way as ordinary options settlement . You fulfill your end of the bargain. As the seller of a put option, you sold the right to sell XYZ at $45. The option buyer exercised that right and sold his shares to you at $45 per share.

And now, let’s break down what happened in this transaction:

  • You collected $1 in premium when opening the contract  
  • The buyer of the option exercises his right to sell at $45 per share.  
  • You’re now long 100 shares of XYZ that you paid $45 for, and you sell them at the market price of $44.80 per share, realizing a $0.20 per share loss.  
  • Your profit on the transaction is $0.80 because you pocketed $1 from the initial sale of the option but lost $0.20 from selling the 100 shares from assignment at a loss.

Why Early Assignment is Nothing to Fear

Many beginning traders count early assignments as one of their biggest trading fears; on some level, it makes sense. As the seller of an option, you’re accepting the burden of a legitimate obligation to your counterparty in exchange for a premium. You’re giving up control, and the early assignment shoe can, on paper, drop at any time.

Exercising Options Early Burns Money

People rarely exercise options early because it simply doesn’t make financial sense. By exercising an option, you’re only capturing the option’s intrinsic value and entirely forfeiting the extrinsic value to the option seller. There’s seldom a reason to do this.

Let’s put ourselves in the buyer’s shoes. For instance, we pay $5 for a 30-day call with a strike price of $100 while the underlying is trading at $102. The call has $2 in intrinsic value, meaning our call is in-the-money by $2, which would be our profit if the option expired today.

The other $3 of the option price is extrinsic value. This is the value of time, volatility, and convexity. By exercising early, the buyer of an option is burning that $3 of extrinsic value just to lock in the $2 profit.

A much better alternative would be to sell the option and go and buy 100 shares of the stock in the open market.

Viewed in this light, an option seller can’t be blamed for looking at early assignment as a good thing, as they get to lock in their premium as profit.

Your Risk Doesn’t Change

One of the biggest worries about early assignment is that being assigned will somehow open the trader up to additional risk. For instance, if you’re assigned on a short call position, you’ll end up holding a short position in the underlying stock.

However, let me prove that the maximum risk in your positions stays the same due to early assignment.

How Early Assignment Doesn’t Change Your Position’s Maximum Risk

Perhaps you collect $2.00 in premium for shorting an ABC $50/$55 bear call spread. In other words, we’re short the $50 call for a credit of $2.50 and long the $55 call, paying a debit of $0.50.

Before considering early assignment, let’s determine our maximum risk on this call spread. The maximum risk for a bear call spread is the difference between the strike minus the net credit you receive. In this case, the difference between the strikes is $5, and we collect a net credit of $2, making our maximum risk on the position $3 or $300.

You wake up one morning with the underlying trading at $58 to find that the counterparty of your short $50 call has exercised its option, giving them the right to buy the underlying stock at $50 per share.

You’d end up short due to being forced to sell the buyer shares at $50. So you’re short 100 shares of ABC with a cost basis of $50 per share. On that position, your P&L is -$800, the P&L on a $55 long call is +$250, on account of you paying $0.50, and the call being $3.00 in-the-money. And finally, because the option holder exercised early, you get to keep the entire credit you collected to sell the $50 call, so you’ve collected +$250.

So your P&L is $300. You’ve reached your max loss. Let’s get extreme here. Suppose the price of the underlying runs to $100. Here are the P&Ls for each leg of the trade:

  • Short stock: -$5,000  
  • Long call: +$4,450  
  • Net credit received from exercised short option: +$250  
  • 5,000 – (4,450 + 250) = $300

While dealing with early assignments might be a hassle, it doesn’t open a trader up to additional risk they didn’t sign up for.

Margin Calls Usually Aren’t The End of the World

Getting a margin call due to early assignment isn’t the end of the world. Believe it or not, stock brokerages have been around for a long time. They have seen early assignments many times before, and they have protocols for it.

Think about it intuitively, your broker allowed you to open the short option position knowing that the capital in your account could not cover an early assignment. Still, they let you make the trade anyways.

So what happens when you get an early assignment that you can’t cover? Your broker issues you a margin call. Once you’re in violation of their margin rules, they pretty much have carte blanche to handle the situation as they wish, including liquidating the assigned stock position at their will.

However, most brokers will give you some time to react to the situation and either decide to deposit more capital, liquidate the position on your own, or exercise offsetting options to fulfill the margin call in the case of an option spread.

Even though a margin call isn’t fun, remember that the overall risk of your position doesn’t change due to an early assignment, and it’s typically not a momentous event to deal with. You probably just have to liquidate the trade.

When Early Assignment Might Occur?

Dividend Capture

One of the few times it might make sense for a trader to exercise an option early is when he’s holding a call that is deep in-the-money, and there’s an upcoming ex-dividend date.

Because deep ITM calls have very little extrinsic value (because their deltas are so high), any negligible extrinsic value is often outweighed by the value of an upcoming dividend payment , so it makes sense to exercise and collect the dividend.

Deep In-The-Money Options Near Expiration

While it’s important to emphasize that the risk of early assignment is very low in most cases, the likelihood does rise when you’re dealing with options with very little extrinsic value, like deep-in-the-money options. Although, even in those cases, the probabilities are pretty low.

However, an options trader that is trading to exploit market anomalies like the volatility risk premium, in which implied volatility tends to be overpriced, shouldn’t even be trading deep-in-the-money options anyhow. Profitable option sellers tend to sell options with very little intrinsic value and tons of extrinsic value.

Bottom Line

Don’t let the  fear of early assignment discourage you from selling options. Far worse things when shorting options! While it’s true that early assignment can occur, it’s typically not a big deal.

How can we help you today, why would a short option be assigned early.

A short option can be assigned at any time because the long option holder has the right to exercise whenever they want. However, there are three primary situations where it is much more likely that you could be assigned early.

A long call holder might exercise their call before the ex-dividend date so that they can collect the dividend. For a detailed explanation of dividend risk, please click here .

Hard-to-borrow (HTB) fees

Certain stocks have hard-to-borrow (HTB) fees. This means that anyone who needs to borrow shares to sell the stock short needs to pay an additional fee. Conversely, anyone who is long the stock could potentially lend their shares out and receive money for doing so. As a result, if you are short calls in a hard-to-borrow stock, then there is a higher possibility of being assigned early because it may be more beneficial for the long call holder to exercise and lend out the shares. In this case, you will be short the stock, and you will have to pay the hard-to-borrow fees. To learn more about hard-to-borrow fees, please click here .

Any deep-in-the-money put is at risk of early assignment. This is because it may be better for a long put holder to exercise their put and sell the stock so they can collect interest on the proceeds from the short sale. If you need to borrow money for the stock purchased from an assignment, you will have to pay interest on those funds.

Eliminate Assignment and Exercise Risk with Index Options

Investing Image - Editorial Use Pexels

T raders have significantly more variables to account for when trading options over stocks. As an equity investor, only the fluctuation of the underlying affects the profit and loss of a position. However, with options, the underlying price, volatility, time, and even expiration and assignment risks need to be accounted for. In this post we will explore the significant advantage of trading index option that is embedded in the European-style cash settlement process. Eliminating a low probability but potentially severe risk of assignment and exercise risk can lead investors to a shorter learning curve and more consistent results. Additionally, with the launch of the XND, the  Nasdaq-100 Micro Index Option , investors can now access the full benefits of Index options in a retail-friendly size.

Why are European Cash Settled options an advantage for traders?

One of the major challenges of options trading is tracking the fluctuations in the underlying security, time, volatility, and interest rates that impact an option's price. These variables already present a challenge for many investors to monitor and account for all of them. However, assignment and exercise risk pose additional headaches for American Style equity options, representing 99% of all stock and ETFs options. As a market strategist, I have witnessed rare but significant exposure with vertical spread trades that have lost substantially more than the max risk of a strategy due to these two risks. European Cash Settled index options outright eliminates these risks.

What is assignment risk, and how can I avoid it?

With American-style options, a call or put can be exercised at any time by the buyer before expiration. Even when a spread is covered by a long option, an early exercise would require a short option holder to have the capital to buy or sell those shares. Most investors with a spread position may not have the cash or margin required to buy or sell the securities of the short leg. Even to exercise the offsetting long option would require the cash or margin to exercise and satisfy the obligation of the short option. For investors without the capital, it forces the broker to liquidate the entire position upon an early exercise.

While this risk cannot be avoided when trading American Style stock or ETF options, European-style Index Options on the Nasdaq-100 eliminate this risk entirely, they simply cannot be exercised early. Especially for new options traders, removing this element of risk is a way to flatten the learning curve and reduce the factors to consider on a trade. However, for investors trading American Style stock or ETF options, this risk can be minimized but not eliminated by closing out short option positions at least two weeks before expiration.

What is exercise risk, and how can I avoid it?

Exercise risks are rare but occur when an investor incorrectly anticipates an underlying security's value immediately after expiration. An example, is a short call or put option that expires worthless and 'out-of-the-Money" (OTM) based on expiration Friday's closing price but opens up Monday' In-the-money" (ITM). In this scenario, a short option investor may be inclined to let their short options expire worthless without buying back the call or put to remove the obligation. However, news, earnings, or other catalysts after the close causes the option buyer to anticipate a favorable move by Monday's open and exercises their option despite it being OTM on expiration Friday. This causes a short option that should have realized its full profit as of Friday's close with no exposure, to be exposed on Monday with a surprise underlying equity position. In comparison, these scenarios are rare but occur when earnings reports or material news are released after the close on Friday. For an index, these could be geopolitical events or macroeconomic news that cause an OTM option buyer to still exercise the call or put.

The best practice for avoiding exercise risk is simply closing out all short option positions, even if they are OTM before expiration. Paying a few cents to buy back a call or put that is nearly worthless will significantly outweigh the risk of exercise risk. However, with European cash-settled index options such as on the Nasdaq-100 Index, options that expire worthless can never be exercised, and gains are settled to cash based on Friday's close, eliminating all exercise risks.

Despite the  benefits and advantages of trading index options , ETF options have historically provided better flexibility on sizing. Index options on the Nasaq-100 Index had large notional value, reducing the ability for smaller retail traders to utilize them. However, with the new  XND product launch , a 1/100 th  value of the full Nasdaq-100 Index, retail traders can have the best of both worlds. XND provides the advantages of index options, with a contract sizing that is roughly a 1/3 rd  of QQQ.

Trading options involve tracking a significant number of variables, including assignment and exercise risk. While both Index and ETF options provide exposure to the same index European style and cash-settled, which eliminate the assignment and exercise risks embedded in an American style option. Moreover, the tax advantage provided by Index options, can lower a tax bill on similar trades. Lastly, the new retail focused XND product, provide investors of all sizes the ability to benefit from the reduced risk of index options.
