Options Strategies
Covered Call
Learn how covered calls exchange some upside for premium while retaining share downside. Includes a worked example, risks and primary sources.
A covered call combines owning shares with selling a call against them. The premium provides limited income and a small downside buffer, but the call caps upside above its strike while the shares retain most downside risk. Assignment may require selling the shares at the strike.

Definition and mechanics
One short call is commonly covered by 100 shares. If shares finish above the strike and assignment occurs, the shares are sold at that strike. If the call expires worthless, the trader keeps the shares and premium.
How to evaluate it
Confirm that the share quantity covers the call obligation and calculate the effective sale price if assigned. Compare the premium buffer with the remaining stock downside and the upside surrendered above the strike. Review dividends, tax consequences, liquidity and early-assignment exposure before treating the premium as income earned without further obligations.
Worked example
Own 100 shares at $50 and sell a $55 call for $1. Maximum expiration gain is generally $600 before fees: $500 share appreciation plus $100 premium.
Risks and limitations
- The premium offsets only a small portion of a large fall in the underlying, while strong upside may be surrendered.
- Options involve risk and can lose part or all of the capital committed. Multi-leg positions also introduce execution, assignment and management complexity.
Common misconception
Reality check
A covered call is not downside protection equivalent to a put; it only provides the premium as a limited buffer.
