How a covered call works
An investor who owns 100 shares of a stock sells one call option against them. The buyer of the call pays a premium for the right to buy the shares at the strike price before expiration. If the stock stays below the strike, the option expires, the investor keeps the premium and the shares, and can repeat the process. If the stock rises above the strike, the shares are sold at the strike price and the investor keeps the premium plus any gain up to the strike, but forgoes the gain above it.
The strategy is called covered because the shares cover the obligation to deliver. It does not protect against the stock falling; the premium offsets a small part of the decline, and the shares are still owned. It is an income strategy on a position the investor would hold anyway, not a hedge.
When it suits a portfolio
- On shares the investor is content to hold long term and content to sell at the strike price.
- In sideways or gently rising markets, when the premium is meaningful relative to expected price movement.
- When implied volatility is elevated, since premiums are higher, provided the reason for the elevated volatility is understood.
- Not on shares with an imminent catalyst such as earnings, unless the investor is willing to sell before the move.
The 5 decisions in every covered call
- 01Which stock. Liquid, with a tight options market, and one you would hold through a decline.
- 02Which strike. Further out of the money keeps more upside and collects less premium; closer collects more and sells more of the rally.
- 03Which expiration. Shorter dates decay faster and require more management; longer dates collect more premium up front and lock the position longer.
- 04When to act early. Rules for closing the call after it has lost most of its value, or rolling it if the stock approaches the strike.
- 05What to record. Premium received, annualised yield, the outcome, and what would be done differently. This is the step that turns trades into skill.
The workbook provides a worksheet for each decision and a log for recording outcomes. It is designed to be used alongside the Goat Academy option trading guide and the live options income session.
Covered calls carry the full downside risk of owning the shares and cap the upside. The workbook is educational and does not recommend any specific trade.
Key points
What to take from this guide
- 01A covered call sells upside above the strike in exchange for premium, on shares already owned.
- 02It is an income strategy for positions you would hold anyway, not protection against a fall.
- 03Stock, strike, expiration, early action rules, and record keeping are the 5 decisions.
