Covered Call Strategy: Generate Income From Stocks You Own
How a Covered Call Works
The setup is simple: you own 100 shares of a stock, and you sell one call option against them. If the stock stays below the strike price by expiration, the option expires worthless and you keep both the shares and the premium. If the stock rises above the strike, your shares get called away — you sell them at the strike price but still keep the premium.
Covered Call Example
You own 100 shares of AAPL at $195. You sell a $205 call expiring in 30 days for $3.00 ($300 total premium).
| Scenario | AAPL at Expiration | What Happens | Total Profit |
|---|---|---|---|
| Stock stays flat | $195 | Option expires worthless, keep shares + premium | +$300 (premium only) |
| Stock rises slightly | $202 | Option expires worthless, keep shares + premium | +$300 + $700 unrealized = +$1,000 |
| Stock rises above strike | $215 | Shares called away at $205, keep premium | +$300 + $1,000 (stock gain) = +$1,300 max |
| Stock drops | $185 | Option expires worthless, still own shares at loss | +$300 – $1,000 unrealized = -$700 |
The Profit and Loss Profile
Breakeven = Stock Purchase Price – Premium Received
Max Loss = Stock Purchase Price – Premium (if stock goes to $0)
In the example above: Max profit = ($205 – $195) + $3 = $13 per share ($1,300). Breakeven = $195 – $3 = $192. You start losing money if AAPL drops below $192.
How to Choose the Right Strike and Expiration
Strike Price Selection
| Strike Selection | Delta | Premium | Probability of Assignment | Best When |
|---|---|---|---|---|
| Deep OTM (10%+ above current) | ~0.10-0.15 | Low | Low (~10-15%) | Very bullish — want upside with small income boost |
| OTM (5% above current) | ~0.25-0.30 | Moderate | Moderate (~25-30%) | Mildly bullish — balanced income and upside |
| ATM (at current price) | ~0.50 | Highest | High (~50%) | Neutral — maximize income, accept limited upside |
Expiration Selection
The sweet spot for covered calls is 30-45 days to expiration. This balances decent premium (enough to be worth the trade) with accelerating time decay that works in your favor. Shorter expirations offer faster decay but require more frequent management. Longer expirations collect more total premium but tie up your position for longer.
When to Use Covered Calls
Covered calls work best in three scenarios: when you’re mildly bullish or neutral on the stock, when implied volatility is elevated (premiums are rich), and when you’re happy to sell the stock at the strike price if it gets called away.
Covered calls are less ideal when you’re strongly bullish (the cap on upside costs you) or when the stock has high downside risk (the premium offers only a small cushion).
Covered Call vs. Other Income Strategies
| Feature | Covered Call | Cash-Secured Put |
|---|---|---|
| Position | Own stock + sell call | Hold cash + sell put |
| Market View | Neutral to mildly bullish | Mildly bullish (willing to buy) |
| Income Source | Call premium | Put premium |
| Risk | Stock declines (you still own it) | Must buy stock if it drops to strike |
| Best For | Stocks you already own | Stocks you want to buy at a discount |
Managing Your Covered Call
Roll the position: If the stock is approaching your strike near expiration and you don’t want assignment, buy back the current call and sell a new one at a higher strike and later date. This lets you keep the shares while continuing to collect premium.
Let it get called away: If the stock surges past your strike, accept the assignment. You locked in a profit (strike price + premium). Chasing stocks higher after selling covered calls leads to whipsaw and frustration.
Buy back early: If the stock drops and the option loses most of its value quickly, buy it back at a discount (e.g., for $0.20 when you sold at $3.00) and sell a new one. No point waiting for the last few cents when you can redeploy.
Key Takeaways
- A covered call = own 100 shares + sell 1 call. You collect premium but cap your upside at the strike.
- Best for neutral-to-mildly-bullish outlooks on stocks you already own.
- The 30-45 day expiration sweet spot balances premium income with theta decay.
- Selling OTM calls (5% above stock price, ~0.25-0.30 delta) offers a good balance of income and upside.
- Manage proactively: roll positions, buy back at 50-80% profit, and don’t fight assignment on strong up-moves.
Frequently Asked Questions
How much can you make selling covered calls?
Returns vary by stock and volatility, but a typical covered call on a moderate-volatility stock yields 1-3% per month in premium. Annualized, that’s 12-36% in additional income on top of any stock appreciation up to the strike. Higher-volatility stocks offer richer premiums but also carry more downside risk.
What happens if your covered call gets assigned?
Your 100 shares are sold at the strike price. You keep the premium plus any gain from the purchase price to the strike. Assignment isn’t a loss — you sold at a price you were comfortable with. If you want the shares back, you can buy them again (or sell a cash-secured put to potentially re-enter).
Can you lose money on a covered call?
Yes — if the stock drops significantly. The premium provides a small cushion, but it doesn’t fully protect against a major decline. If you bought AAPL at $195, received $3 in premium, and the stock falls to $170, you’re down $22 per share ($25 drop – $3 premium). The premium only reduces your loss, it doesn’t eliminate it.
Should you sell covered calls on dividend stocks?
Covered calls pair well with dividend stocks because you collect both the dividend and the call premium. However, be aware of early assignment risk around ex-dividend dates — in-the-money call holders may exercise early to capture the dividend.
Is a covered call the same as a buy-write?
A buy-write means you buy the stock and sell the call simultaneously as a single trade. A covered call uses shares you already own. The payoff profile is identical — the difference is just whether you’re initiating or already holding the stock position.
