Covered Call Strategy
Get paid to wait — earn income from shares you already own.
What is the Covered Call Options Strategy?
A Covered Call is the most popular income strategy for stock investors. You already own 100 shares. You sell a call option against them, collecting a premium immediately. If the stock stays below the strike, you keep the premium and your shares. If it rises above, your shares are called away at the strike — but you still keep the premium.
Think of it like renting out your shares. You own a house (the stock). You rent it out (sell a call) and collect rent (the premium). If the tenant wants to buy at the agreed price, you sell at that price — which you were already happy with.
It is not a "free money" trade — you give up unlimited upside above the strike. But in flat or mildly bullish markets, it is one of the most reliable ways to generate consistent income from a stock position.
Why is it Called "Covered Call"?
"Covered" means the risk of the short call is covered by the shares you already own. If the stock is called away, you can deliver the 100 shares you hold — you are not exposed to unlimited loss like a naked call seller. "Call" is the option you sell — the right you grant someone else to buy your shares at the strike price.
How Does the Covered Call Trade Work?
- 1 Step 1 — Own 100 shares of a stock you are comfortable holding long-term.
- 2 Step 2 — Choose a call strike above the current price (usually 2–5% OTM for 30–45 days out).
- 3 Step 3 — Sell 1 call contract per 100 shares. The premium is credited to your account immediately.
- 4 Step 4 — At expiry: if the stock is below the strike, the call expires worthless — you keep shares and premium. Repeat.
- 5 Step 5 — If the stock rises above the strike, you are assigned — your shares are sold at the strike price. You keep the premium. Your total return = (strike − cost basis) + premium.
Types of Covered Call Strategies
ATM Covered Call
Sell a call at the current stock price. Highest premium collected. High chance of assignment (shares being called away). Best if you are happy selling at the current price.
OTM Covered Call (Most Common)
Sell a call above the current price. You keep the premium AND participate in stock gains up to the strike. Lower premium but more room for the stock to run. Best when mildly bullish and want upside participation.
Deep OTM Covered Call
Sell a call far above the current price. Very low premium but maximum stock upside is preserved. Used mainly when you want income with near-zero chance of assignment.
Rolling the Covered Call
When the stock approaches your strike before expiry, you "roll" — buy back the short call and sell a new one at a higher strike or later expiry. Extends the trade and avoids assignment while collecting more premium.
When to Use the Covered Call Strategy?
- When you hold a stock and want to earn income in a flat or mildly bullish market
- When implied volatility is elevated — higher IV means more premium
- When you are comfortable selling your shares at the strike price if assigned
- Monthly income generation on long-term holdings (popular in F&O on Nifty50 stocks)
- When you want to lower your effective cost basis over time through repeated premium collection
Profit and Loss of the Covered Call
Before looking at the chart, here is a plain-English summary of what you can make and what you can lose.
Capped at (strike − cost basis) + premium received. Once the stock exceeds the strike, your gain is locked — you cannot benefit from further upside.
Substantial if the stock falls sharply. The premium collected provides a small cushion but does not fully protect the downside. Effective breakeven = cost basis − premium received.
Your stock cost basis minus the premium collected. If you paid ₹1,000 for the stock and collected ₹30 premium, you break even at ₹970.

The chart below shows how profit/loss changes with the underlying price at expiry. Green zone = profit, red zone = loss.
Covered Call Example Trade
| Action | Type | Strike | Premium |
|---|---|---|---|
| Own | Stock | ₹2,500 | (already held) |
| Sell | Call | ₹2,600 | +₹45 |
RELIANCE stays at ₹2,520 at expiry. The ₹2,600 call expires worthless. You keep your 100 shares AND the ₹45 premium. That is ₹4,500 income in 30 days. Sell another call next month. Repeat 12 times a year.
Pros & Cons of the Covered Call
- Generates immediate income from shares you already hold — no extra capital required
- Lowers your effective cost basis over time through repeated premium collection
- Reduces breakeven on your stock position — the premium is a buffer against small declines
- Simple 1-leg structure — easiest income strategy to manage and understand
- Works well in flat, sideways, and mildly bullish markets where stocks drift rather than trend
- Caps your upside — if the stock surges past the strike, you miss all gains above it
- Does not fully protect against large drops — premium offsets only a small portion of a big fall
- Assignment risk: if the stock spikes above the strike, your shares are called away — you may regret selling
- In strongly bullish markets, covered calls consistently underperform simply holding shares
- Tax implications on assignment (short-term capital gains if shares held < 1 year in India)
