Covered call is an income-generating options strategy where you own shares of a stock and sell call options against those shares. The calls are “covered” because you own the underlying shares. You collect premium income but agree to sell your shares at the strike price if the stock rises above it. It’s one of the most popular and conservative options strategies.
- Own 100 shares + sell 1 call option
- Collect premium income
- Caps upside but reduces cost basis
How Covered Calls Work
Covered calls generate income from stock holdings:
Covered Call Example:
Own: 100 shares at $100 ($10,000 investment)
Sell: 1 $105 Call expiring in 30 days
Premium Collected: $2.00 per share ($200)
Scenarios at Expiration:
Stock at $110 (above strike):
Sell shares at $105
Keep $200 premium
Total: $105 + $2 = $107/share
Profit: $700 (but missed $300 upside)
Stock at $100 (unchanged):
Keep shares worth $100
Keep $200 premium
Cost basis reduced to $98/share
Stock at $95 (down):
Keep shares worth $95
Keep $200 premium
Loss reduced: $500 - $200 = $300
Quick Reference: Covered Call Outcomes
| Stock at Expiry | Shares | Premium | Net Result |
|---|---|---|---|
| Above strike | Sold at strike | Keep | Capped profit |
| Below strike | Keep | Keep | Reduced loss/gain |
Example: Monthly Covered Calls
Systematic Income Strategy:
| Month | Stock | Strike | Premium | Outcome |
|---|---|---|---|---|
| Jan | $100 | $105 | $2.00 | Kept shares |
| Feb | $102 | $107 | $2.25 | Kept shares |
| Mar | $105 | $110 | $2.50 | Called away |
| Total | $6.75 | + appreciation |
Covered calls own stock and sell calls against it for income. You keep the premium no matter what. If stock rises above the strike, you sell shares at that price. If it stays below, you keep shares and can sell more calls. Popular income strategy for long-term holders.
