In this lesson
Describe what happens to your shares and cash when a covered call is assigned, recognize when early assignment is more likely, and compare being assigned with buying the call back.
Covered call assignment is what happens when the owner of the call you sold exercises it: your 100 shares are sold at the strike price, you receive the strike times 100 in cash, and you keep the premium you collected when you sold the call. Assignment is not a loss in itself: if the strike is above what you paid, it locks in the covered call's maximum profit. What it takes away is the stock, and any gain above the strike.
This lesson uses the trade from What Is a Covered Call?: 100 XYZ bought at $48 and one XYZ 52 call sold for $0.80, 30 days from expiration. It is hypothetical and is not a recommendation to trade.
How does covered call assignment work?
The owner of the call, not you, decides whether to exercise it. When they do:
- The Options Clearing Corporation (OCC) assigns the exercise to a brokerage firm with short positions in that call. The Options Industry Council explains that OCC uses a random procedure for this.
- Your broker assigns it to one of its customers who is short the call, using a method it discloses, such as random selection.
- Your 100 shares are delivered at $52. You receive $5,200, and the call is gone.
How covered call shares get called away

Your broker assigns you
By its disclosed method
Shares delivered
100 XYZ sold at $52: receive $5,200
At expiration, an equity call that finishes at least $0.01 in the money is normally exercised automatically under the OCC's exercise-by-exception procedure, unless its owner instructs otherwise (your broker's threshold may differ), as the Options Industry Council's exercise FAQ describes. So if XYZ closes above $52 on expiration day, plan on the shares being gone by the next trading day. If it closes below $52, the call normally expires worthless and you keep the shares. A close very near the strike is less certain, because the owner may still choose to exercise based on after-hours news.
Worked example
XYZ closes at $55 on expiration day
Your shares are called away at $52. Before fees, the trade's result is:
- Stock: bought at $48, sold at $52: +$400.
- Premium: collected when you sold the call: +$80.
- Total: $480, the trade's maximum profit, on the $4,800 you put in.
A shareholder who sold no call would still own the shares, now worth $5,500: a $700 gain on paper. The $220 difference is what the call cost you: the upside from $52 to $55, less the $80 premium.
Illustrative and hypothetical. The ticker and prices are invented for teaching, and the figures exclude commissions, fees, margin interest and taxes, which reduce real results. Past or hypothetical outcomes do not indicate future results.
Why would a covered call be assigned early?
Most U.S. stock options are American-style: the owner can exercise on any business day before expiration, so you can be assigned early. It is unusual while the call still has meaningful time value, because exercising throws that time value away. Selling the call would be worth more to its owner.
The main exception is a dividend. The Options Industry Council's covered call guide says early assignment is more likely the day before a stock goes ex-dividend, and that it "would deprive the covered call writer of the stock dividend." The owner of an in-the-money call may exercise to own the shares in time for the dividend when the dividend is worth more than the time value they give up by exercising.
Worked example
Early assignment before a dividend
XYZ is at $55 with three days left on your 52 call. The call is worth about $3.06: $3.00 of intrinsic value and only about $0.06 of time value. XYZ goes ex-dividend tomorrow with a $0.25 dividend.
- For the call's owner: exercising today gives up about $0.06 of time value and gains a $0.25 dividend. That can be worth doing.
- For you: if you are assigned tonight, your shares are sold at $52. You keep your $480 maximum profit, but you do not receive the dividend.
The $3.06 is a model value that ignores the dividend. Real quotes would reflect it, which is one more reason to check the actual time value before an ex-dividend date.
Illustrative and hypothetical. The ticker and prices are invented for teaching, and the figures exclude commissions, fees, margin interest and taxes, which reduce real results. Past or hypothetical outcomes do not indicate future results.
Deep in-the-money calls carry the same risk at any time. When a call trades for little more than its intrinsic value, there is little time value to protect, and an assignment can come on any day. Check the call's time value, not just how many days are left, and check how your broker notifies you of an assignment, since that varies by firm.
How do you keep your shares if the call is in the money?
If you want to keep XYZ, you have two choices before you are assigned:
- Buy the call back. Close the short call with a buy-to-close order. The Options Industry Council's assignment FAQ calls this the "most obvious and straightforward" way to avoid assignment, because it assures that the stock will not be called away.
- Roll it. Buy the call back and sell another one at a later expiration, a higher strike or both, in one order. How to Roll a Covered Call works through the numbers.
Buying back an in-the-money call costs more than you collected, which can feel like a loss. Look at the whole position instead. Near the close on expiration day, with XYZ at $55, the call trades for about its $3.00 intrinsic value:
- The call: sold for $0.80, bought back for $3.00: -$220.
- The shares: bought at $48, still owned at $55: +$700 on paper.
- Total: $480, exactly the result of being assigned.
XYZ finishes at $55: three ways the month ends
Profit on the month, XYZ at $55
Buying back the call does not make the month better or worse. It changes what you hold afterward: shares instead of cash. Before expiration, the buyback also costs any remaining time value, so it is slightly worse than the assignment math above.
Assignment is also a sale of the shares, with tax consequences. The IRS adds the call premium to the sale proceeds when a call you wrote is exercised, and has special "qualified covered call" rules that depend on the strike, the time to expiration and where the option trades; see IRS Publication 550 and a tax professional for your situation.
Check your understanding
You own 100 shares bought at $30 and sold a 33 call for $0.60. The stock closes at $36 on expiration day. What happens, and what is your result?
Show answer
The call is normally exercised and your shares are sold at $33. You make $3 a share on the stock plus the $0.60 premium, $360 in total before fees. You give up the move from $33 to $36.
When is early assignment of a covered call most likely?
Show answer
When the call is deep in the money with little time value left, and especially the day before the stock goes ex-dividend, when the dividend can be worth more to the call's owner than the time value they give up.
Why does buying back an in-the-money call at expiration give the same result as being assigned?
Show answer
The loss on the call is offset by the gain on the shares you keep, up to the strike. At $55 the call costs $220 more than you collected, and the shares are $700 higher, so the total is the same $480 either way.
Key takeaways
- Assignment sells your 100 shares at the strike; you keep the premium and the position closes.
- An equity call at least $0.01 in the money at expiration is normally exercised, unless its owner instructs otherwise.
- Early assignment is most likely on deep in-the-money calls and just before an ex-dividend date.
- To keep the shares, buy the call back or roll it before you are assigned; it changes what you hold, not the month's result.
Common questions
What happens if my covered call gets assigned?
Your 100 shares are sold at the strike price and the cash from the sale lands in your account. You also keep the premium you collected when you sold the call. The position is closed: no shares and no call remain.
Can a covered call be assigned early?
Yes. Most U.S. stock options are American-style, so the owner of the call can exercise on any business day before expiration. Early assignment is uncommon while the call still has meaningful time value, but becomes more likely when it is deep in the money or just before the stock goes ex-dividend.
How do I avoid assignment on a covered call?
Buy the call back before you are assigned, or roll it to a later expiration or a higher strike. Both cost more when the stock has risen above the strike. A position closed during the trading day cannot be assigned that night.
Do I lose money if my covered call is assigned?
Not compared with what you paid, if the strike is above your share price: you sell at the strike and keep the premium, which is the trade's maximum profit. What you give up is any gain above the strike, which a plain shareholder would have kept.
