Covered Call
is an options strategy where you sell call options against shares you already own, collecting premium income in exchange for capping your upside potential at the strike price.
Covered calls are the most popular options income strategy, used by millions of investors to generate 1-3% monthly returns on their stock portfolios with minimal additional risk.
Quick answer
Selling covered calls: Own 100 shares, sell 1 call against them. Collect premium = instant income. Best practices: 30-45 DTE, 0.20-0.30 delta (OTM), close at 50-75% profit. Monthly income: 1-3% of stock value. Risk: stock gets called away above strike (you keep premium + stock gains to strike). The safest options strategy for stock owners.
A covered call sells one call per 100 shares owned, collecting premium and capping upside at the strike while leaving full downside exposure.
How Selling Covered Calls Works
Selling covered calls is the simplest options income strategy: own 100 shares of a stock, sell one call option against them, and collect premium. That premium is yours to keep regardless of what happens. It's like collecting rent on property you own.
Example: You own 100 shares of MSFT at $400. You sell the $420 call expiring in 30 days for $5.00, collecting $500 immediately. Three outcomes: 1) MSFT stays below $420—option expires worthless, you keep $500 and your shares. 2) MSFT rises above $420—shares called away at $420, you keep $500 premium + $2,000 stock gain = $2,500 total profit. 3) MSFT drops—you keep the $500, which offsets some of the stock decline.

Choosing the Right Strike and Expiration
Strike Selection (Delta-Based)
Use delta as your guide: 0.15-0.20 delta = conservative (85% chance of keeping shares, lower premium). 0.25-0.30 delta = balanced (70-75% chance, moderate premium). 0.35-0.40 delta = aggressive (60-65% chance, higher premium). Most investors prefer 0.20-0.30 delta for the best risk-reward balance.
Expiration Selection
Sell calls with 30-45 days to expiration. This is the sweet spot where theta decay is meaningful but you're not taking excessive gamma risk. Weekly options offer more premium per day but require more active management.
Managing Your Covered Calls
Profit target: Close at 50-75% of maximum profit. If you sold a call for $5.00, buy it back when it drops to $1.25-2.50. Then sell a new call for the next cycle.
If tested (stock approaches strike): Roll out in time for a credit. If you can't roll for a credit, either let the stock be called away (take your profit) or roll out and up for a small debit.
Avoid selling through earnings: IV spikes before earnings make covered calls tempting, but the risk of a large gap up (losing upside) or gap down (stock loss exceeds premium) makes it risky. Close before earnings, reopen after.

Questions
What people ask
about this.
How much can I make selling covered calls?
Typical covered call income is 1-3% per month on the stock value, or 12-36% annually. On a $50,000 stock portfolio, that's $500-1,500/month. Returns depend on implied volatility (higher IV = more premium), time to expiration, and strike selection. This income supplements dividends and capital gains.
What strike should I sell for covered calls?
Sell calls at the 0.20-0.30 delta level, which is approximately 5-10% out-of-the-money. This provides 70-80% probability of keeping your shares while still collecting meaningful premium. If you're willing to sell the stock, choose a closer strike for more premium.
What happens if my covered call gets assigned?
If assigned, your 100 shares are sold at the strike price. You keep the premium collected plus any stock gain up to the strike. This is actually a profitable outcome—you made money on both the stock appreciation and the premium. Many covered call sellers are happy to be assigned.
