Covered Calls: Income from Stocks You Own
A covered call sells call options against stock you already own, generating premium income while capping upside on the position.
Covered Calls: Income from Stocks You Own
A covered call is one of the simplest and most popular option strategies. You own 100 shares of a stock, and you sell one call option against those shares. In return, you collect a premium — cash you keep no matter what happens. The trade-off: if the stock rallies past the strike, your upside is capped.
How It Works
- Own (or buy) 100 shares of a stock
- Sell 1 call option against those shares
- Collect the premium immediately
- Wait until expiration (or buy the call back earlier)
| Outcome | What Happens |
|---|---|
| Stock stays below strike | Keep shares + premium |
| Stock rises above strike | Shares called away at strike + premium kept |
| Stock falls | Loss on shares offset by premium kept |
Example
You own 100 shares of XYZ at $50. You sell a $55 call expiring in 30 days for $1.50 ($150 total premium).
- If XYZ stays below $55 → keep shares, keep $150
- If XYZ rises above $55 → sell shares at $55, keep $150 (capped upside)
- If XYZ falls to $45 → shares worth $4,500, but you keep $150 premium (net cost basis $48.50)
Why Investors Use Covered Calls
- Generate income — Premium adds to returns beyond dividends
- Lower cost basis — Effective purchase price drops by the premium
- Mildly bullish to neutral — Earns while the stock moves sideways
- Defined outcome — Risks and rewards are clear upfront
Choosing Strike and Expiration
| Choice | Effect |
|---|---|
| Higher strike | Lower premium, more upside if called away |
| Lower strike | Higher premium, more likely to be assigned |
| Longer expiration | More premium, slower theta decay |
Most covered call sellers choose strikes above the current price (out-of-the-money) to keep some upside.
Risks and Downsides
- Capped upside — If the stock soars, you miss gains above the strike
- Stock still falls — Premium cushions but doesn't eliminate losses
- Assignment risk — Shares can be called away anytime (usually near expiration or dividend dates)
- Opportunity cost — Capital tied up in shares while collecting modest premiums
Strategy Tips for Beginners
- Only sell against shares you're willing to sell at the strike
- Avoid earnings dates unless you want the volatility risk
- Check ex-dividend dates — Early assignment is common before dividends
The Takeaway
Covered calls turn stock you already own into an income engine. They're beginner-friendly, defined-risk, and useful in flat markets. Just remember: you're trading upside for cash today. Sell calls only on shares you'd happily sell at the strike, and the strategy becomes a steady, low-stress part of an income portfolio.
