Covered Call Strategy: How to Use It with an Example
What Is a Covered Call Strategy?
A covered call strategy is an options trading strategy where you own a stock and sell a call option on the same stock.
When you sell the call option, you receive a premium from the buyer. In return, you agree to sell your shares at a fixed price, called the strike price, if the buyer exercises the option before or on expiry.
Since you already own the shares, your position is "covered." This makes the strategy less risky than selling a call option without owning the underlying stock.
Most traders use a covered call strategy when they expect the stock price to remain stable or rise only slightly.
You may also hear a covered call strategy referred to as a buy-write strategy. The term "buy-write" is typically used when you buy the stock and sell the call option at the same time. The end position is the same as a covered call.
How Does a Covered Call Strategy Work?
A covered call strategy has two parts.
First, you own the shares.
Second, you sell a call option against those shares.
Here's how it works.
Buy or already own the stock.
Sell a call option with your preferred strike price and expiry.
Receive the option premium immediately.
Wait until expiry.
After that, one of three things can happen.
If the stock stays below the strike price, the option expires worthless. You keep both your shares and the premium.
If the stock moves above the strike price, your shares may be sold at the strike price. You still keep the premium.
If the stock falls, you continue to own the shares. The premium helps reduce your loss, but it does not eliminate it.
Covered Call Strategy Example
Let's understand the strategy with a simple example.
Suppose you own 100 shares of ABC Ltd.
Buy Price = Rs. 1,000 per share
Current Market Price = Rs. 1,000
Strike Price = Rs. 1,050
Premium Received = Rs. 20 per share
Expiry = One month
Now let's see three possible outcomes.
This example shows why a covered call works best when the stock moves sideways or rises slightly.

When Should You Use a Covered Call Strategy?
A covered call is not suitable for every market condition.
You should consider using it when:
You already own the stock.
You expect the stock to remain sideways.
You expect only a small rise in price.
You want to generate additional income from your holdings.
You should avoid using it if:
You expect a strong rally.
The stock is highly volatile.
A major event like earnings is approaching.
In these situations, your upside may be limited because your shares could be sold at the strike price.

Advantages of a Covered Call Strategy
There are several reasons why traders use this strategy.
1. Earn Regular Premium Income
Every time you sell a call option, you receive a premium. This creates an additional source of income from stocks you already own.
2. Slight Downside Protection
The premium you receive reduces your overall cost of holding the stock. While it does not prevent losses, it offers a small cushion if prices fall.
3. Easy to Understand
Compared to many advanced options strategies, a covered call is straightforward. This makes it suitable for beginners who already understand the basics of options trading.
4. Works Well in Sideways Markets
Many stocks spend weeks moving within a range. A covered call allows you to earn income even when prices do not move significantly.
Risks and Limitations
Like every trading strategy, a covered call also has limitations.
1. Limited Profit
If the stock rises well above the strike price, your profit is capped. You must sell your shares at the agreed strike price.
2. Stock Price Risk
Owning the stock means you still face downside risk if the share price drops sharply.
3. Assignment Risk
If the option buyer exercises the contract, your shares may be sold even if you wanted to continue holding them.
Understanding these risks before trading helps you make better decisions.
