The strike price you choose on a covered call is the single most important decision you make when entering the trade. Get it right and you collect solid income while keeping room to profit. Get it wrong and you either earn barely anything or cap yourself out of a great move.
The Three Zones
At-the-money (ATM) — Sell the strike closest to the current stock price. You collect the most premium, but any upside is immediately capped. Best in flat or slightly bearish environments when you want maximum income and don't mind giving up appreciation.
Out-of-the-money (OTM) — Sell a strike 5–10% above current price. Less premium, but you participate in some upside before getting capped. This is the sweet spot for most income investors — you still collect meaningful premium while giving the stock breathing room.
Deep OTM — Sell a strike 15–20%+ above price. Very little premium. You'll barely notice the income. Only makes sense if you're extremely bullish and mostly want a small "rent check" on shares you'd never sell anyway.
What Else Affects Strike Selection
- Implied volatility: When IV is high, OTM strikes pay more. You can go further out-of-the-money and still collect good premium.
- Your outlook: Bullish on the stock? Go further OTM. Neutral or mildly bearish? Move closer to ATM for more income now.
- Ex-dividend date: If ex-div is within the option's life, avoid deep ITM strikes — early assignment risk goes up significantly.
- Upcoming earnings: Don't sell calls through earnings unless you want to be surprised. Let earnings pass, then sell.
The Simple Rule
Pick a strike you'd be comfortable selling the shares at. If AAPL is at $195 and you'd be happy selling at $210, sell the $210 call. If getting called away at that price would bother you, go higher — or don't sell the call at all that month.
