Selling covered calls is a simple, conservative way to try and generate extra monthly income from shares you already own. In India, this strategy works well for liquid, well-established stocks and ETFs that have active option markets. The idea is to get paid a premium every month while retaining ownership of the shares, unless they are called away.
Start with the basics
Buy and hold a stock you are comfortable keeping for months or years. Then, sell a call option on that same stock with the same or higher expiry (typically monthly). By selling the call you receive an immediate premium paid in ₹. If the option expires worthless, you keep the premium and can sell another call next month. If the option is exercised, you sell the stock at the agreed strike price and still keep the premium.
Why people use covered calls
- Income generation: Premiums add regular cash flow, which can feel like monthly passive income.
- Downside buffer: The premium reduces your effective cost basis slightly, helping absorb small drops in price.
- Simplicity: Compared to other F&O trades, covered calls are easier to understand and manage.
A simple numeric example
Assume you own shares of a reliable company bought at ₹500 per share. You sell a one-month call with a strike of ₹520 and receive a premium of ₹5 per share. For 100 shares this premium would be ₹500. That is roughly a 1% return for the month (₹5/₹500). If repeated monthly, it could approximate 12% annual income before tax, brokerage and slippage. If the stock rises past ₹520 and gets called away, you still sell at ₹520 plus keep the ₹5 premium, giving you a capital gain plus the income.
Key choices to make
- Choose strike: Selling an out-of-the-money (OTM) strike gives more upside potential on the stock but lower premium. An in-the-money (ITM) strike gives higher premium but higher chance of assignment (getting called away).
- Expiry: Monthly options are common. India also has weekly expiries for many stocks; use whichever matches your plan and liquidity needs.
- Pick liquid stocks: Look for stocks with good option open interest and tight bid-ask spreads (e.g., large-cap banks, IT firms, FMCG). Liquidity lowers trading costs and slippage.
Practical steps to follow
Risk management and common pitfalls
- Upside cap: If the stock rallies strongly beyond your strike, you miss further upside above the strike price. If you want to keep upside potential, choose a higher strike.
- Assignment risk: Be prepared to sell shares at the strike. If you want to avoid being assigned, buy back the call before close on expiry day, but this can cost money.
- Margin and costs: Check brokerage, exchange fees and taxes. Some brokers may show margin for option-writing even for covered positions; confirm cash-secured or margin treatment.
- Earnings and events: Avoid selling close to earnings or corporate actions unless you intentionally want that volatility and higher premium.
- Tax and accounting: Premiums and sales affect capital gains. If options expire, premiums are typically short-term gains; if your shares are sold due to exercise, the sale triggers capital gains calculation based on your holding period. Consult a chartered accountant for details.
Tips to improve outcomes
- Start small: Try the strategy on one or two stocks to learn mechanics.
- Use a covered-call checklist: liquidity, low cost, dividend schedule, upcoming events.
- Keep a rolling plan: If assigned, you can buy back and re-establish the position later or switch to another stock.
- Track returns after fees and taxes. Gross premium numbers look attractive but net returns are what matters.
A quick note on alternatives
If you prefer less risk of assignment or want broader diversification, consider selling calls on ETFs that track large-cap indices. Alternatively, writing cash-secured puts is another approach to potentially buy stocks at a discount while earning premiums.
Start slowly, keep learning from each trade, and adjust strike and timing to match your goals. If unsure about tax or margin effects, speak to your broker or a chartered accountant before building a full strategy.

Practical steps to follow
- Buy the underlying shares and confirm the option lot/contract size as per exchange rules.
- Select a strike and expiry that match your risk-return comfort.
- Sell the call (write the option) and collect the premium.
- Monitor until expiry: if it expires worthless repeat; if exercised, accept sale or consider buying back before exercise.
