Covered Call Options Strategy Guide

When it makes sense

• You own shares you are happy to keep, and happy to sell at a higher price
• You expect the stock to drift or rise modestly, not to rip higher
• Implied volatility is elevated, so the premium you collect is rich
• You want to lower your cost basis on a position you are holding anyway

Quick reference

How it works

Hold 100 shares and sell one call with a strike above the current price, typically 15 to 60 days out. The premium is credited immediately. If the stock finishes below the strike, the call expires worthless, you keep the premium and the shares, and you can sell another call. If it finishes above the strike, the shares are called away at the strike: you keep the premium plus the gain from your cost basis to the strike. Breakeven on the whole position at expiration is your share cost minus the premium collected.

Risk and reward

Maximum profit: the premium plus the distance from the current price to the strike, times 100. Maximum loss: the stock falling to zero minus the premium, so the downside is the same as owning the stock outright, cushioned by the credit. Breakeven: stock cost minus premium. Returns on covered calls are best judged per month as a percent of the share price. As a rough guide, a 30-day call a few percent out of the money on a liquid large cap often pays somewhere around 1 to 2% of the share price, and more on volatile names; the actual figure depends on implied volatility and the strike you choose, so treat that as a range to screen against rather than an expectation.

Greeks and volatility

The combined position has a positive delta that is smaller than 100 shares (100 minus the call's delta), so it still rises with the stock but more slowly. Theta is positive: time decay on the short call is income to you every day. Vega is negative, so a drop in implied volatility after you sell helps, and a spike hurts on paper until expiration. Because a covered call has the same expiry payoff as a short put at the same strike, it shares the short put's character: limited upside, full downside.

Managing the trade

Early assignment is the practical risk. Equity options are American style, and a short call that is in the money right before an ex-dividend date is likely to be assigned by a holder who wants the dividend when the call's remaining time value is less than the dividend, taking your shares the day before the payout. Either avoid strikes that will be in the money at ex-div, or accept assignment as the plan. If the stock runs past the strike and you want to keep the shares, roll the call up and out for a net credit or small debit. If the stock falls, the call's value drops and it can be bought back cheaply to reset at a lower strike, though rolling down locks in a lower cap.

What to screen for

Screen by premium yield (the credit as a percent of the stock price), annualized return if called, days to expiration, and how far out of the money the strike sits. Add an ex-dividend filter so you are not surprised by assignment, and an earnings filter if you do not want the report inside the trade window. The scanner's dividend-yield-on-strike column shows the total income if you hold the shares through a dividend and the call expires.

Frequently asked questions

Can I lose money on a covered call?

Yes. The premium only cushions the first few percent of a decline; if the stock drops further, the position loses like stock. The call limits upside, not downside.

What happens if my covered call is assigned?

Your 100 shares are sold at the strike price. You keep the premium and any gain up to the strike. Assignment is a normal outcome, not a problem, unless you wanted to keep the shares.

Why was my call assigned before expiration?

Almost always because of a dividend. If the call was in the money and its remaining time value was less than the upcoming dividend, the holder exercised to capture the payout.

What strike should I sell for a covered call?

Many sellers work with strikes around 0.20 to 0.35 delta and 15 to 45 days out as a balance of premium and room to run. That is a common convention, not a rule: sell closer to the money for more income, further away if you expect a rally or want to keep the shares.

Is a covered call the same as a cash-secured put?

At expiration the payoff is the same shape: capped upside, full downside. A cash-secured put is the position before you own shares; a covered call is the position after. Together they make the wheel strategy.
