What Is a Covered Call?

In short

Explains what a covered call is, how the premium and strike work together, and the difference between a covered and naked call, with a full worked example on XYZ.

Selling a covered call means getting paid today for agreeing to sell stock you already own, at a price you pick, if it gets there.

What a covered call is

A covered call only works on stock you already hold. You sell someone else the right to buy 100 of your shares at a price you choose — called the strike — before a set date. They pay you a premium up front for that right, and you keep it no matter what happens next. It's "covered" because you already own the 100 shares you'd need to hand over if the buyer exercises.

A worked example

You own 100 shares of XYZ, currently trading at $48, with a cost basis of $45. You sell one call contract, $52 strike, 30 days out, for a $1.10 premium.


Premium collected (100 × $1.10)	$110
Your obligation	Sell 100 shares at $52 if the buyer exercises
If XYZ stays below $52 at expiration	Call expires worthless; you keep the shares and the $110
If XYZ rises above $52 at expiration	Shares are called away at $52; you keep the $110 plus the gain from $45 to $52

Either way, the $110 is yours. The only open question is whether you end the trade still holding the shares, or having sold them at $52.

Why traders sell them

Covered calls turn stock you're already holding into a source of regular income. They make the most sense on shares you'd genuinely be happy to sell at the strike — you're essentially getting paid to set that exit price in advance, instead of waiting and hoping for better.

Covered vs. "naked" — why it matters

When an option buyer exercises, the seller on the other side is "assigned." A naked call — sold without owning the stock — leaves the seller having to buy shares on the open market, at whatever price they've risen to, just to deliver them at the lower strike. That loss has no ceiling. A covered call seller already owns the shares, so assignment just means handing over stock that's already in the account. No scramble, no open-ended risk.

The risk, plainly

A covered call caps your upside at the strike. If XYZ rallies to $70 instead of $52, you still only get $52 a share — you miss the extra $18. And the premium isn't real protection on the downside either: if XYZ drops to $35, the $110 barely dents that loss. Think of a covered call as trading away some upside for premium income, not as insurance against the stock falling.

Key takeaway: You always keep the premium — the real question a covered call asks is whether you're comfortable selling your shares at the strike price if the stock gets there.
