What you will learn
- Construct a covered call from stock plus a short call
- Compute its maximum profit and breakeven
- Understand the income-for-upside trade-off
- Know when the strategy fits and its key risk
With the mechanics of options established, the rest of the unit turns to strategies. The first is one of the most popular and accessible: the covered call, an income strategy built on stock you already own. It is a gentle introduction to options strategies, and it shows the basic trade-off between income and upside.
Covered calls for beginners (projectoption)
Walks through the covered call step by step. Focus on the premium income and the capped upside.
The construction
A covered call combines two positions: you own shares of the underlying, and you sell a call option against those shares. It is called covered because you own the shares needed to deliver if the option is exercised, unlike a naked call, where the seller owns nothing and faces unlimited risk. By selling the call, you collect the premium up front, the source of the strategy's income.
The income and the trade-off
The appeal is the premium income. You receive the premium immediately, earning return from a stock you already hold, and as the call seller you benefit from time decay, the positive theta that erodes the option in your favor. But this income caps your upside. If the stock rises above the strike, the call buyer exercises and your shares are called away at the strike. You keep the premium and any gain up to the strike, but you forgo appreciation beyond it. You traded unlimited upside for a certain premium.
Key terms
- Covered call
- Owning stock and selling a call against it to collect premium income.
- Called away
- Having your shares sold at the strike when the call buyer exercises.
- Naked call
- Selling a call without owning the stock, exposing the seller to unlimited risk.
- strike = the sold call's strike
- purchase price = what you paid for the shares
- premium = the call premium collected
- purchase price = what you paid for the shares
- premium = the call premium collected
A covered call's profit and breakeven
You own a stock bought at 50 dollars and sell a call with a 55 strike for a 2 dollar premium. What is your maximum profit per share, and your breakeven?
- Max profit. (strike − purchase price) + premium is (55 − 50) + 2, which is 5 plus 2, or 7 dollars.
- Breakeven. Purchase price − premium is 50 − 2, which is 48 dollars.
- Interpret. You make at most 7 dollars per share, and you start losing only below 48.
Why it matters: The 2 dollar premium gives a small downside cushion (down to 48) and adds to your gain up to the strike, but caps your total profit at 7, no matter how high the stock goes.
Covered call max profit
You own a stock bought at 100 dollars and sell a call with a 105 strike for a 3 dollar premium. What is your maximum profit per share, in dollars?
A covered call sells your upside for cash. If the stock soars, you collected a small premium and watched the big gain go to someone else.
A smarter way to think about covered calls (tastylive)
A more nuanced take on when covered calls make sense. Watch for the view the strategy expresses.
When it makes sense, and the key risk
The covered call suits a neutral-to-mildly-bullish view. If you expect the stock to stay flat or rise modestly, you earn premium while the capped upside is unlikely to matter. It is a poor fit when you are strongly bullish, because you would forfeit exactly the large gains you expect. And there is a key risk: you still bear the full downside of owning the stock. The modest premium is only a small cushion, so a covered call does not protect you against a sharp decline. It is an income strategy in the right conditions, not a hedge against serious losses, which is exactly what the next lesson, protective puts, provides.
Does the covered call protect you?
You hold a covered call: stock bought at 50, short a 55 call for a 2 dollar premium. The stock crashes to 30. What happens?
A covered call gives up upside for premium, it does not hedge the downside. When the stock crashes from 50 to 30, you lose 20 per share on the stock, cushioned only by the 2 dollar premium, for a net 18 loss. For real protection you need a protective put.Income for upside
In your own words, explain the core trade-off a covered call makes and the type of market view it suits.

Model answer
A covered call trades away the stock's unlimited upside in exchange for a certain, immediate premium. By selling a call against shares I own, I collect income and benefit from time decay, but if the stock rises above the strike my shares get called away, so I keep only the gain up to the strike plus the premium and miss any larger rally. That makes it best suited to a neutral-to-mildly-bullish view, where I expect the stock to stay flat or rise only a little, so the capped upside costs me nothing I expected to get. It is a poor choice if I am strongly bullish, since I would give up the big gains I am counting on, and it does not protect me if the stock falls sharply.
The covered call earns income but leaves your downside exposed. The next lesson does the opposite: it pays for downside protection with a protective put.
