Covered Call Strategy in India: How to Earn Extra Income on Shares You Own
You hold shares for the long term. Some months they barely move. A covered call lets you earn a monthly “rent” on those shares by selling call options against them.
This guide explains the covered call strategy in India with a full rupee example, the payoff in three scenarios, Indian rules on settlement and margin, and when the strategy works best.
What Is a Covered Call?
A covered call has two parts:
- You own the shares (at least one lot of the stock).
- You sell a call option on the same stock, usually out of the money.
You collect the call premium upfront. The call is “covered” because, if the buyer exercises, you already own the shares to deliver. For a short definition, see our covered call FAQ. If calls are new to you, read call and put options explained first.
Covered Call Example in Rupees
You own 500 shares (assume 1 lot = 500) of a stock bought at ₹1,500. It now trades at ₹1,520.
You sell one monthly ₹1,600 call for a premium of ₹20.
- Premium received: ₹20 × 500 = ₹10,000
- That is about 0.66% of your ₹7.6 lakh holding in one month.
Payoff in Three Scenarios at Expiry
| Stock price at expiry | Shares gain/loss (from ₹1,520) | Call outcome | Net result |
|---|---|---|---|
| ₹1,450 (falls) | −₹35,000 | Expires worthless, keep ₹10,000 | −₹25,000 |
| ₹1,560 (rises a little) | +₹20,000 | Expires worthless, keep ₹10,000 | +₹30,000 |
| ₹1,700 (rallies) | +₹90,000 | Call loses ₹50,000 (₹100 × 500), minus ₹10,000 premium received | +₹50,000 (capped) |
The pattern is clear. The premium cushions small falls and boosts returns in a flat market. In a strong rally, your upside is capped at the strike: maximum gain = (strike − current price + premium) × quantity = (₹1,600 − ₹1,520 + ₹20) × 500 = ₹50,000.
Why Covered Calls Work: Theta
The call you sell loses time value every day. As the seller, that decay is your income. It is the opposite of what option buyers face, as our guide to theta decay in options shows.
Rules Specific to India
- Stock options are physically settled. If your sold call is in the money at expiry, your shares are delivered. Close or roll the call before expiry if you want to keep the shares.
- Margin is needed to sell a call. Most brokers let you pledge the shares you own as collateral, but part of the margin may need to be in cash. Our guide to margin in the stock market explains pledging.
- Lot sizes are fixed. You need shares equal to at least one lot. Check current lot sizes on NSE.
- Monthly expiry only for stocks. Single-stock options expire on the last Tuesday of the month on NSE.
- Tax. Option premium income is generally treated as non-speculative business income, separate from capital gains on the shares. See our stock market tax guide and consult a CA.
How to Choose the Strike
| Strike choice | Premium | Chance of shares being called | Best when |
|---|---|---|---|
| Near the money | High | High | You expect a flat market |
| 3–5% out of the money | Medium | Medium | Mildly bullish, want income + some upside |
| 8–10% out of the money | Low | Low | Bullish, want to keep shares |
Many traders pick a strike near a strong resistance level, where the stock has struggled to cross before.
When to Avoid a Covered Call
- Before results or big news, when a gap-up could cap a large gain.
- On stocks you are very bullish on.
- On illiquid stock options with wide bid-ask spreads.
- When you cannot afford the downside of the shares themselves. A covered call reduces risk only slightly; it does not protect you from a crash.
Covered Call vs Simply Holding
| Hold only | Covered call | |
|---|---|---|
| Flat market | No return | Earns premium |
| Small fall | Full loss | Loss reduced by premium |
| Big rally | Full upside | Upside capped |
| Effort | None | Monthly management |
Frequently Asked Questions
Is a covered call strategy safe? It is lower risk than naked call selling, but you still carry the full downside of the shares, minus the premium.
What happens if my covered call is exercised in India? Stock options are physically settled, so your shares are delivered at the strike price. You keep the premium.
Can I do a covered call on Nifty? Not directly, because you cannot own the index in delivery. Traders use Nifty futures or ETFs with careful margin planning, which adds risk.
How much can I earn from covered calls? It depends on volatility and strike. Many traders target 0.5–1.5% a month, but income varies and is never guaranteed.
Do I need a big capital for covered calls? You need enough to hold one full lot of the stock, which usually means a few lakh rupees.
Conclusion
A covered call turns idle holdings into monthly income, at the cost of capping big gains. It suits flat-to-mildly-bullish views and investors who already own a full lot.
