Options Exercise, Assignment, and More: A Beginner's Guide
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 expiration day approaches and, at the time, XYZ is trading at $105.30.
Wait. The stock's above the strike. Is that in the money 1 (ITM) or out of the money 2 (OTM)? Do I need to do something? Do I have enough money in my account? Help!
Don't be that trader. The time to learn the mechanics of options expiration is before you make your first trade.
Here's a guide to help you navigate options exercise 3 and assignment 4 —along with a few other basics.
In the money or out of the money?
The buyer ("owner") of an option has the right, but not the obligation, to exercise the option on or before expiration. A call option 5 gives the owner the right to buy the underlying security; a put option 6 gives the owner the right to sell the underlying security.
Conversely, when you sell an option, you may be assigned—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. Once the assignment notice is delivered, it's too late to close the position and the option seller must fulfill the terms of the options contract:
- A long call exercise results in buying the underlying stock at the strike price.
- A short call assignment results in selling the underlying stock at the strike price.
- A long put exercise results in selling the underlying stock at the strike price.
- A short put assignment results in buying the underlying stock at the strike price.
An option will likely be exercised if it's in the option owner's best interest to do so, meaning it's optimal to take or to close a position in the underlying security at the strike price rather than at the current market price. After the market 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.
- If the underlying stock price is...
- ...higher than the strike price
- ...lower than the strike price
- If the underlying stock price is... A long call is... -->
- ...higher than the strike price ...ITM and typically exercised -->
- ...lower than the strike price ...OTM and typically abandoned -->
- If the underlying stock price is... A short call is... -->
- ...higher than the strike price ...ITM and typically assigned -->
- If the underlying stock price is... A long put is... -->
- ...higher than the strike price ...OTM and typically abandoned -->
- ...lower than the strike price ...ITM and typically exercised -->
- If the underlying stock price is... A short put is... -->
- ...lower than the strike price ...ITM and typically assigned -->
The guidelines in the table assume 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 more than one company stock, or underlying shares and cash. Other products—such as index options or options on futures—have different contract specs.
- Stock and options positions will match and close . Suppose you're long 300 shares of XYZ and short one ITM call that's assigned. Because the call is deliverable into 100 shares, you'll be left with 200 shares of XYZ if the option is assigned, plus the cash from selling 100 shares at the strike price.
- 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 (DNE) 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 7 ?
- You'd better have enough cash . If an option on XYZ is exercised or assigned and you are "uncovered" (you don't have an existing long or short position in the underlying security), a long or short position in the underlying stock will replace the options. A long call or short put will result in a long position in XYZ; a short call or 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 8 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 your account to meet a margin call 9 . 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 long put, if assigned or exercised, will result in a short stock position. If you're short a stock, you have potentially unlimited risk because there's theoretically no limit to the potential price increase of the underlying stock. 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 an options position into expiration if there's a chance you might end up with a short stock position.
A note on pin risk : It's not common, but occasionally a stock settles right on a strike price at expiration. So, if you were short the 105-strike 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 price up or down through the strike price? Remember: The owner of the option could submit a DNE request.
The uncertainty and potential exposure when a stock price and the strike price are the same at expiration is called pin risk. The best way to avoid it is to close the 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.
1. 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, the unexpected turn of events 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 (a short 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 selling the stock at the $110 strike price to monetize the $10 profit (plus the premium you took in when you sold the call but minus any transaction fees). In that case, you can let assignment happen. But remember, assignment is likely in this scenario, but it is not guaranteed.
2. Close it out . If you've met your objectives for a trade, then 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). 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.
The close-it-out category also includes ITM options that could result in an unwanted long or short stock 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 option position well in advance—perhaps a week or more.
3. Roll it to something else . Rolling, which is essentially two trades executed as a spread, is the third choice. One leg closes out the existing option; the other leg initiates a new position. For example, suppose you're short a covered call on XYZ at the July 105 strike, the stock is at $103, and the call's about to expire. You could attempt to 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 include 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 making your first trade.
1 Describes an option with intrinsic value (not just time value). A call option is in the money (ITM) if the stock price is above the strike price. A put option is ITM if the stock price is below the strike price. For calls, it's any strike lower than the price of the underlying equity. For puts, it's any strike that's higher.
2 Describes an option with no intrinsic value. A call option is out of the money (OTM) if its strike price is above the price of the underlying stock. A put option is OTM if its strike price is below the price of the underlying stock.
3 An options contract gives the owner the right but not the obligation to buy (in the case of a call) or sell (in the case of a put) the underlying security at the strike price, on or before the option's expiration date. When the owner claims the right (i.e. takes a long or short position in the underlying security) that's known as exercising the option.
4 Assignment happens when someone who is short a call or put is forced to sell (in the case of the call) or buy (in the case of a put) the underlying stock. For every option trade there is a buyer and a seller; in other words, for anyone short an option, there is someone out there on the long side who could exercise.
5 A call option gives the owner the right, but not the obligation, to buy shares of stock or other underlying asset at the options contract's strike price within a specific time period. The seller of the call is obligated to deliver, or sell, the underlying stock at the strike price if the owner of the call exercises the option.
6 Gives the owner the right, but not the obligation, to sell shares of stock or other underlying assets at the options contract's strike price within a specific time period. The put seller is obligated to purchase the underlying security at the strike price if the owner of the put exercises the option.
7 When the stock settles right at the strike price at expiration.
8 Margin is borrowed money that's used to buy stocks or other securities. In margin trading, a brokerage firm lends an account owner a portion of the purchase price (typically 30% to 50% of the total price). The loan in the margin account is collateralized by the stock, and if the value of the stock drops below a certain level, the owner will be asked to deposit marginable securities and/or cash into the account or to sell/close out security positions in the account.
9 A margin call is issued when your 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 a customer exceeds their buying power. Margin calls may be met by depositing funds, selling stock, or depositing securities. Charles Schwab may forcibly liquidate all or part of your account without prior notice, regardless of your intent to satisfy a margin call, in the interests of both parties.

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.
