Choosing a Strike and Expiration for a Covered Call

The strike you pick sets your exit price for the stock; the expiration sets how long you're committed to it.

The trade-off in one sentence

A strike close to today's price pays a bigger premium but leaves little room before your shares get called away. A strike further away pays less but gives the stock more room to run first.

A worked comparison

You own XYZ at $50, currently trading at $55. Here's how three 30-day call strikes compare:

The $56 strike pays the most, but the stock is already almost there — a small rally triggers assignment. The $65 strike pays very little, but XYZ would need to climb almost 20% before that call is ever at risk of being exercised.

Expiration matters just as much

A shorter-dated call (say, 7-14 days) pays less premium per contract, but lets you reassess and pick a new strike again soon. A longer-dated call (45-60 days) pays more per contract, but locks in that strike — and that exit price — for longer, with less room to adjust if your view on the stock changes.

What actually drives the choice

There's no single "correct" strike or expiration — it depends on what you want out of the position:

• A strike close to the price, sold often, maximizes premium income and treats being called away as a fine outcome.
• A strike further from the price keeps you in the stock longer, and only lets you get called away if the rally is substantial.

Both are legitimate ways to run a covered call. They just reflect different goals for the same shares.

The risk, plainly

Picking the strike purely to chase the biggest premium — without being genuinely fine selling at that price — turns "get paid to set an exit price" into "get paid to give up a stock you didn't actually want to sell yet." And whatever strike you choose, the obligation is firm: if the stock finishes above it, your shares are sold there, even if the market has since climbed well past it. Standard equity options can be assigned early too, not just at expiration — most commonly right before the stock's ex-dividend date. Once assigned, the shares are gone at the strike, no matter what the stock does afterward.

Key takeaway: Choose a strike you'd genuinely be happy selling at — chasing premium alone can cost you a stock you meant to keep.
