Why Assignment Happens
A call holder exercises when there's no benefit to holding the option anymore. This happens when:
Your job is to keep time value alive or close the position before these conditions occur.
Technique #1: Roll Before It's Too Late
Rolling means buying back your current call and selling a new one with a later expiration. The key: do this before the call goes deep in the money.
Example: You sold a $150 call on AAPL. The stock is now at $154 with 5 days to expiration. The call is $4.20 with only $0.20 of time value.
You've moved your strike up $5 and pushed expiration out a month. If AAPL stays below $155, you won't be assigned.
Technique #2: Sell Further Out of the Money
If you keep getting assigned, your strikes are too aggressive. Move to a lower delta:
| Delta | Approx. Monthly Assignment Rate |
Dropping from 0.30 to 0.15 delta cuts your assignment frequency roughly in half. You'll collect less premium, but you'll keep your shares far more often.
Technique #3: Close Profitable Calls Early
Buy back your call when it reaches 50-80% of maximum profit. Don't let a profitable position ride into the final week, where gamma risk can turn a safe OTM call into an ITM one overnight.
Rule of thumb: Close at 50% profit if there are 14+ days left. Close at 65-80% profit if there are 7-14 days left. Roll or accept assignment in the final 5 days.
Technique #4: Avoid Selling Through Ex-Dividend Dates
If your stock pays dividends and your call is in the money, you're at high risk of early assignment the day before ex-dividend. The call holder exercises to capture the dividend.
Prevention: Check the ex-dividend date before selling a call. Either sell calls that expire before the ex-date, or sell far enough OTM that the call won't be ITM when the ex-date arrives.
OptionsPilot flags ex-dividend dates on your positions so you can plan your covered calls around them.
Technique #5: Use Longer Expirations
Calls with 45-60 DTE have more time value than weekly calls. More time value means less incentive for early exercise. A 45-day call that's $1 in the money might have $3 of time value — nobody's exercising that.
A 3-day call that's $1 in the money might have $0.15 of time value — that's getting exercised.
When Assignment Is Actually Fine
Sometimes the best move is to accept it. If:
Let it happen. Sell a cash-secured put to re-enter at a lower price, and you've started the wheel strategy.
