Covered Calls: The Complete Guide
Covered Calls
Key Takeaways
- A covered call means selling a call option on stock you already own, generating income from your existing holdings.
- You collect premium upfront and keep it regardless of outcome.
- Your upside is capped at the strike price, but you profit from premium + any stock appreciation up to that level.
- Ideal for stocks you own and are willing to sell at a target price.
TL;DR
Covered calls let you earn premium income on stock you already own by selling someone the right to buy your shares at a higher price. You keep the premium no matter what. If the stock rises past your strike, shares get called away at a profit. If it stays flat or dips, you keep your shares and the premium.
What Is a Covered Call?
A covered call has two parts:
- Own 100 shares of the underlying stock
- Sell 1 call option against those shares
The call is "covered" because you already hold the shares to deliver if the buyer exercises. This makes it one of the safest options strategies. You're generating income from an asset you already own.
Your broker will require you to hold 100 shares per contract. No margin needed for the options side since the stock itself is the collateral.
How the Mechanics Work
When you sell a covered call:
- You choose a strike price above the current stock price (how high you're willing to sell)
- You choose an expiration date (typically 30-45 days out)
- You collect premium immediately: this money is yours to keep
Three possible outcomes:
Stock stays below strike → Option expires worthless. You keep premium + shares. Sell another call next month.
Stock rises above strike → Shares are "called away" (sold at strike price). You profit from stock appreciation + premium.
Stock drops → Option expires worthless. You keep premium, which partially offsets the paper loss on your shares.
Trade Example: Microsoft Covered Call
You own 100 shares of MSFT at $350.
You sell a $370 call expiring in 30 days and collect $5/share ($500 premium).
Scenario A: MSFT at $355 at expiration:
Call expires worthless. You keep $500 + your shares.
Return: $500 / $35,000 = 1.4% in one month (17% annualized).
Scenario B: MSFT at $385 at expiration:
Shares called away at $370. You receive $37,000.
Total profit: $2,000 (stock gain) + $500 (premium) = $2,500.
Scenario C: MSFT drops to $330:
Call expires worthless. You keep $500. Paper loss on stock: $2,000.
The premium reduced your loss from $2,000 to $1,500.
Strike Selection Strategy
Your strike price choice reflects a risk-reward tradeoff:
Near the money (e.g., $355 when stock is $350)
- Higher premium collected
- Higher probability of being called away
- Best for: maximum income, willing to sell
Further out of the money (e.g., $380 when stock is $350)
- Lower premium
- More room for stock appreciation
- Best for: want to keep shares, still earn some income
The sweet spot: Most covered call sellers target strikes with a 0.20-0.30 delta: roughly a 20-30% chance of being called away. This balances premium income with the probability of keeping your shares.
When to Sell Covered Calls
Good times: After a stock has run up (higher premiums from elevated IV), during sideways markets, on stocks you'd sell at the strike price anyway.
Bad times: Right before earnings (risk of a big gap up past your strike), when you're strongly bullish and don't want to cap upside, on stocks with upcoming catalysts you want to hold through.
Golden rule: Only sell covered calls on shares you're comfortable selling at the strike price.
Common Mistakes
Selling calls too close to the money: Higher premium, but you'll get called away frequently and miss upside moves.
Selling through earnings: Stocks can gap 10-20% on earnings. If your strike is below the gap, you miss a huge gain.
Not tracking cost basis: When shares get called away, your true profit includes all premiums collected over the life of the position. Track everything.
Panic buying back calls at a loss: If the stock rises above your strike, don't panic. You agreed to sell at that price. Let the trade play out or roll the call up and out.
