What Is a Covered Call?
A covered call is an options strategy where you sell a call option on a stock you already own. The shares you hold "cover" your obligation if the buyer exercises the option. In return for selling the call option, you receive the option premium immediately as income, regardless of what happens next.
How Covered Calls Work
Suppose you hold 500 shares of Infosys at Rs 1,800 per share. You sell a call option with a strike price of Rs 1,900 and collect a premium of Rs 30 per share (Rs 15,000 total). If Infosys stays below Rs 1,900 by expiry, the option expires worthless, and you keep the Rs 15,000 premium. If Infosys rises above Rs 1,900, your shares are called away at Rs 1,900, capping your upside but still giving you the Rs 100 gain plus the Rs 30 premium.
When to Use Covered Calls
- Sideways or mildly bullish market: Covered calls earn extra income when you expect the stock to stay range-bound.
- Long-term holdings: Investors holding blue-chip Indian stocks like TCS, Reliance, or HDFC Bank can generate regular income by writing monthly calls.
- Portfolio enhancement: Covered calls reduce your effective purchase price over time, improving returns on stagnant positions.
Covered Calls in Indian Markets
In India, stock options are available for NSE-listed F&O stocks. To write covered calls, you must own at least one lot worth of shares (lot sizes vary by stock). For Nifty, you would need to hold Nifty ETF units equivalent to the lot size or trade index options through a portfolio-based approach. SEBI's margin rules require that the held shares be pledged as collateral with the broker to offset margin requirements.
Risks and Limitations
The main risk of covered calls is opportunity cost: if the stock surges far above your strike price, you miss out on the full upside because your shares get called away at the strike. Additionally, if the stock falls significantly, the premium collected partially offsets losses but does not protect against a large decline. Covered calls are not a full hedge against downside risk.
Key Takeaway
Covered calls are one of the most conservative options strategies and a practical way to generate regular income from long-term stock holdings. By selling upside potential above the strike price, you receive premium income that cushions minor declines and boosts returns in flat markets.
