Track this covered call in your portfolioFigures are at expiry, before taxes, and use today's share price as the base for returns. Annualized returns scale the period return by 365 divided by the days to expiry, without compounding. A dividend counts only if you still hold the shares on the ex-dividend date. The chance of being called is a Black-Scholes estimate from the volatility you enter, not a forecast, and early assignment isn't modeled; it is most likely when the call is in the money just before an ex-dividend date. Not investment advice.
A covered call is a popular options strategy where you sell (write) a call option against shares of stock you already own. For every call contract sold, you must hold at least 100 shares of the underlying stock, making the position "covered."
When you sell a covered call, you receive premium income upfront. In exchange, you agree to sell your shares at the strike price if the buyer exercises the option. This strategy is used by investors who want to:
The trade-off is that your upside is capped at the strike price. If the stock surges well above the strike, you miss out on gains beyond that level. However, many income-focused investors consider this an acceptable trade-off for the certainty of premium income.
Understanding the math behind covered calls helps you evaluate opportunities and compare strategies. Here are the key formulas:
DTE = Days to Expiration. All premiums are per-share values. Multiply by 100 for per-contract amounts. In the last line S is the share price less any dividend due before expiry, K the strike, r the interest rate, σ the implied volatility and t the years to expiry (DTE / 365).
Example: You own 100 shares of XYZ at $50 and sell a $55 call for $2.00 premium with 30 days to expiration.

Covered call maximum profit equals (Strike Price - Purchase Price + Premium) multiplied by the number of shares. This is achieved when the stock closes at or above the strike at expiration and your shares are called away. If the stock stays below the strike, your profit is limited to the premium received, but you keep your shares and can sell another call.
The maximum loss on a covered call is (Purchase Price - Premium Received) per share, which occurs if the stock drops to zero. The premium you collected provides a small buffer but does not eliminate the downside risk of owning the stock. This is why covered calls are considered a moderately bullish to neutral strategy, not a hedge against major declines.
Annualized return normalizes your covered call premium to a yearly rate: (Premium / Stock Price) × (365 / Days to Expiration) × 100. This lets you compare calls with different expirations. A $1 premium on a $50 stock over 30 days yields 24.3% annualized, while the same premium over 60 days yields only 12.2%. Shorter-duration calls typically offer higher annualized returns but require more active management.
It depends on your investment goals. If you picked the strike price as your target selling price, letting the call be exercised locks in your planned profit. If you want to keep the shares, consider rolling the position before expiration by buying back the current call and selling one at a later date or higher strike. Rolling costs money, so factor that into your decision. Many systematic sellers simply let assignment happen and then start again with a cash-secured put.
