The covered call, end to end
A covered call is selling someone the right to buy 100 shares you already own, at a price you choose, in exchange for cash you keep no matter what happens. You give up the gains above that price. That is the entire trade: you are paid a fixed amount today to cap your upside.
Every explanation of this trade starts with the same diagram and skips the part people actually get wrong. So here is one complete trade with every number shown, and then the part people get wrong.
The setup
You own 200 shares of KO. You bought them a while back at $62.80 and they are trading at $71.40. You like the company, you are in no hurry to sell, and you would be mildly annoyed but not upset if the shares went away at $75.
One options contract covers 100 shares. You own 200, so you can write at most two contracts and still be covered. Write a third and that one is naked, which is a different trade with a different risk profile and, at most brokers, a different permission level.
The trade
On March 14 you sell 2 contracts of the April 24 expiry, $75 strike, for $0.62 each.
- Credit received: $0.62 x 100 x 2 = $124, in your account that day.
- What you promised: to sell 200 shares at $75 each, any time before April 24, if the buyer asks.
- Days to expiry: 41.
- Your break-even on the shares: $62.80 minus $0.62 = $62.18. The premium lowers it.
The $124 is yours immediately and permanently. There is no scenario where you give it back. That is worth being clear about because a lot of people picture the premium as somehow at risk. It is not. What is at risk is the upside above $75.
The three ways this ends
KO closes below $75 on April 24. The call expires worthless. You keep the shares and the $124. This is the outcome you want and, for a strike this far out of the money, the most likely one by some distance. Write another one on Monday.
KO closes above $75. The call finishes in the money and you are assigned. Your 200 shares are sold at $75 whether KO is at $75.10 or $94. You collect $15,000 for the shares plus the $124 premium, against a cost basis of $12,560. Total profit $2,564. That is a good outcome that will feel like a bad one if KO is at $94, and managing that feeling is most of what separates people who keep doing this from people who quit.
KO falls to $64. The call expires worthless, you keep the $124, and your shares are down $1,480 from where they were on March 14. The premium covered 8 percent of the decline. It was never going to cover much more. A covered call is not a hedge and anyone selling it to you as downside protection is describing a rounding error.
The part people get wrong
The mistake is thinking of the premium as free money and the assignment as an accident. It is the reverse. You were paid $124 because there is a real chance KO trades above $75, and the market priced that chance. If assignment never happened, nobody would pay you anything.
Which leads to the rule that saves this strategy: only write a call at a strike where you would genuinely be content to sell. Not a strike you think will not get hit. A strike where, if it gets hit, you shrug. Those are different tests and the second one is the only one that survives contact with a stock that rips 30 percent.
What it costs you
Over one 41-day window on one dividend-paying large cap, capping upside at $75 costs you almost nothing, because KO going up 5 percent in six weeks is unlikely. Do it every month for ten years on a stock that compounds and the cost is enormous. That is not a hypothetical: it is the single most important thing to understand about this strategy, and it has its own page at covered calls versus buy and hold, where the numbers are not kind.
Covered calls convert an uncertain, unbounded return into a smaller, steadier one. If that trade appeals to you, this works. If you own the stock because you think it triples, writing calls against it is working against yourself.
What you actually need before you place one
- 100 shares per contract. No exceptions, no partial coverage.
- Options approval at your broker. Covered calls are usually the lowest tier, often Level 1.
- A strike you would be happy selling at. See above. This is the whole game.
- A liquid chain. If the bid is $0.55 and the ask is $0.90, the $0.62 you were hoping for is optimistic and the spread just ate a quarter of your premium.
OptionsKing scores every candidate strike on a deterministic 0 to 100 scale and shows you nothing below 60, at any setting, with 75 the recommended bar. How it works covers what that guarantees.
Questions people actually ask
Can I lose money on a covered call?
Yes, on the shares. If the stock falls, you lose on the stock and the premium only offsets a small part of it. The option itself cannot cost you more than the upside you gave up above the strike.
What happens if I want my shares back?
Buy the call back before expiry. If the stock has fallen, that costs less than you sold it for and you keep the difference. If it has risen sharply, buying it back can cost several times the credit you took, which is the real risk of writing calls on something you did not want to sell.
Do I keep the dividend?
If you still own the shares on the ex-dividend date, yes. Being assigned before that date means the shares, and the dividend, go to the call holder. See covered calls and dividends.
How much can I make?
The premium, plus any gain up to the strike. Both are capped and known before you place the trade, which is the appeal. On the KO example that ceiling is $2,564 and no market outcome pays you more.
