Covered Call

What Is a Covered Call?

A covered call is an options strategy where an investor who owns at least 100 shares of a stock simultaneously sells (writes) a call option on that stock. The position is "covered" because the short call obligation is backed by the stock ownership; if the call is exercised, you deliver shares you already own rather than buying them at market price.

Covered calls are the most widely used options strategy among individual investors, favored for their simplicity, income generation, and modest risk reduction.

Why Covered Calls Matter

Covered calls generate income in exchange for capping upside potential:

• Premium income: The premium collected adds to total return. Selling monthly covered calls can generate 1-3% per month in additional income, or 12-36% annualized if the stock cooperates
• Downside buffer: The premium provides a small cushion against declines. If you collect $3 in premium on a $100 stock, your effective cost basis drops to $97
• Volatility monetization: When implied volatility is high, premiums are elevated, allowing you to sell "expensive" options on stock you already own
• Forced discipline: The strategy naturally implements a sell discipline by committing you to exit at the strike price if reached

Covered Call Payoff Profile

The covered call has a defined payoff shape:

• Maximum profit: Achieved when the stock is at or above the strike price at expiration. Equals (Strike - Purchase Price) + Premium
• Breakeven: Stock purchase price minus premium received
• Maximum loss: Occurs if the stock goes to zero (unlikely). Equals purchase price minus premium received

This profile is equivalent to selling a cash-secured put at the same strike, which is known as put-call parity in action.

Best Practices

• Stock selection: Choose stocks you want to own long-term. Covered calls work best on stable, dividend-paying stocks where you are comfortable holding through drawdowns
• Expiration timing: 30-45 DTE captures the acceleration in theta decay without excessive gamma risk
• Strike selection: 1-2 standard deviations OTM (roughly 5-10% above current price) balances premium income with upside participation
• Rolling: If the stock approaches the strike before expiration, you can "roll" the call to a later expiration and/or higher strike to avoid assignment while collecting additional premium
• Earnings avoidance: Consider not having covered calls open through earnings, as a positive surprise could cause a large gap above your strike, resulting in significant missed upside
