Covered calls are a common options strategy for generating additional portfolio income. Rather than depending solely on dividends and capital gains, you can generate income by collecting option premiums on shares or ETFs you already own.
How Covered Calls Work
A covered call is when you sell a call option against shares you already own and agree to sell the shares at the strike price if the option is exercised in return for the premium.
For example, an investor owns 100 shares of a stock at $100 and sells a call with a $105 strike for a $200 premium. The investor keeps the shares unless the option is exercised.
Three outcomes are possible:
- The stock remains below $105. The option expires worthless, so the investor keeps the $200 premium and the shares.
- The shares rise above $105. The stock can be called away at $105, capping the upside, but the investor keeps the premium.
- The stock goes down. The investor keeps the premium, which partly offsets the stock’s fall.
Income Beyond Dividends
Covered calls can provide extra income, particularly in a flat or slightly rising market. You can generate regular income by selling options with various expiries and collecting premiums continuously.
Premiums are not guaranteed profits, and income will vary with market volatility, strike selection, and expiry dates.
Understanding the Trade-Off
The primary downside of covered calls is giving up potential upside. If the share price rises significantly, you’re locked in at the strike price and miss potential gains.
Covered calls offer limited downside protection. A large move against the underlying can exceed the premium received, so treat it as a conservative income generator rather than a protective strategy.
Covered Calls as a Portfolio Overlay
Covered calls can be used as an options overlay within a diversified portfolio. You can hold your core stock and ETF positions and generate extra return via the option premium.
The strategy can be adapted to the market conditions, the investor’s income objectives, and their appetite to sell the underlying positions.
The Bottom Line
Covered calls are a straightforward way to generate extra portfolio income without buying new securities or taking on uncovered call exposure. For many investors, they are a sensible and reassuring way to add to their portfolio.
The aim isn’t to maximize the option premium at all costs but to generate extra return while balancing income, upside, and investment risk.
For investors who already have shares or ETFs in their portfolio, a disciplined covered call approach can be a useful element of a diversified portfolio as they continue to hold those shares.
