Covered Calls Explained: A Beginner-Friendly Options Strategy
A covered call is when you sell a call option on a stock you already own, in exchange for a cash payment called a premium. It’s called “covered” because you own enough shares to deliver if the buyer decides to exercise the option.
Of all the options strategies out there, covered calls are usually the first one beginners learn, and for good reason. They’re built on stock you already hold, the risk is easier to understand than most options trades, and the goal is simple: generate extra income from shares that might otherwise just sit in your account.
This guide walks through how covered calls work, a real example with numbers, and the trade-offs worth knowing before you try one.
How a Covered Call Works
To run a covered call, you need two things:
- At least 100 shares of a stock (since one options contract covers 100 shares)
- A willingness to sell those shares at a set price if the option gets exercised
Here’s the basic sequence:
- You own 100 shares of a stock.
- You sell (write) one call option against those shares, choosing a strike price above the current stock price and an expiration date.
- You immediately receive the premium, in cash, for selling that option.
- If the stock stays below the strike price by expiration, the option expires worthless. You keep the premium and your shares.
- If the stock rises above the strike price, the option may get exercised, and you sell your 100 shares at the strike price. You keep the premium plus the gain up to the strike, but you miss out on any gains above it.
A Real Example, Step by Step
Say you own 100 shares of a stock trading at $50 each, worth $5,000 total. You decide to sell a covered call with a $55 strike price, expiring in 30 days, for a premium of $1.50 per share.
Since one contract equals 100 shares, you receive $150 in premium ($1.50 x 100), deposited into your account right away.
From here, there are two main outcomes:
Outcome 1: The Stock Stays Below $55
If the stock closes below $55 at expiration, the option expires worthless. You keep the $150 premium and you still own your 100 shares. You could then sell another covered call for the next month if you want to repeat the process.
Outcome 2: The Stock Rises Above $55
If the stock climbs to, say, $60, the option buyer will likely exercise their right to buy your shares at $55. You sell your 100 shares at $55 each, receiving $5,500, plus you keep the $150 premium. Your total gain is the $500 rise in stock value (from $50 to $55) plus the $150 premium, for $650 total.
Notice what you didn’t get: the extra $5 per share the stock rose beyond your $55 strike. That upside went to the option buyer, not you. This capped upside is the central trade-off of covered calls.
Why Investors Use Covered Calls
- Extra income: the premium adds cash flow on top of any dividends or stock gains
- Some downside cushion: the premium slightly offsets a stock price drop, since you collected that cash upfront
- A way to sell at a target price: if you already planned to sell your shares at a certain price, selling a call at that strike gets you paid while you wait
In practice, many investors use covered calls on stocks they’d be comfortable holding long term, and on shares they wouldn’t mind selling if the price hits their strike.
Covered Calls: What You Gain and What You Give Up
| Scenario | What Happens | Your Outcome |
|---|---|---|
| Stock falls | Option expires worthless | Keep shares and premium, but stock value drops |
| Stock stays flat | Option expires worthless | Keep shares and premium |
| Stock rises above strike | Option gets exercised | Shares sold at strike, keep premium, miss gains above strike |
Risks and Limits of Covered Calls
Covered calls are often described as a “conservative” options strategy, but they’re not risk-free.
- You still own the stock, so if the price drops sharply, you lose value on your shares. The premium only offsets a small part of that loss.
- Your upside is capped at the strike price. If the stock jumps well above it, you miss out on those extra gains.
- If you don’t want to sell your shares, you’ll need to buy back the call option before expiration (which costs money) or risk having your shares called away.
- Selling calls repeatedly on a stock you’re bullish on long term can mean giving up significant upside over time.
This is educational content, not financial advice. Covered calls involve real risk, including losses on the underlying stock, and results will vary depending on market conditions. It’s worth understanding the tax treatment and mechanics through your broker or a financial professional before placing a trade.
Who Might Consider Covered Calls?
Covered calls tend to fit investors who:
- Already own at least 100 shares of a stock they’re comfortable holding
- Expect the stock to stay flat or rise modestly, not skyrocket
- Want to generate some extra income from an existing position
- Are okay with selling their shares at the strike price if the stock rises past it
They tend to fit less well for investors who strongly expect a stock to make a big move upward, since the strategy caps how much of that move you get to keep.
Key Takeaways
- A covered call means selling a call option on stock you already own, collecting a premium in exchange.
- You need at least 100 shares per contract, since options cover shares in blocks of 100.
- If the stock stays below the strike price, you keep your shares and the premium.
- If the stock rises above the strike price, your shares may be sold at that price, capping your upside.
- Covered calls generate income but come with real trade-offs, including limited upside and continued downside risk on the stock.
Frequently Asked Questions
Do I need 100 shares to sell a covered call?
Yes. One options contract covers 100 shares, so you need at least 100 shares of the underlying stock to sell one covered call. If you own fewer shares, you can’t cover the contract with stock you own.
What happens if my covered call gets exercised?
Your shares are sold automatically at the strike price, and the cash from that sale (plus the premium you already collected) lands in your account. You no longer own those shares unless you buy them back on the open market.
Can I lose money with a covered call?
Yes. If the stock price drops significantly, your shares lose value, and the premium you collected only offsets a small part of that loss. The premium does not fully protect you from a falling stock price.
How do I choose a strike price for a covered call?
Many beginners choose a strike price above the current stock price, at a level where they’d be satisfied selling their shares. A strike closer to the current price usually pays a higher premium but increases the odds your shares get sold.
Is a covered call the same as a naked call?
No, and this distinction matters a lot. A covered call is backed by shares you already own. A naked (or uncovered) call means selling a call without owning the underlying shares, which can expose you to much larger, potentially unlimited losses if the stock price rises sharply.
