Covered Call Strategy on Indian Stocks: Earn Monthly Income

The covered call is the most beginner-friendly income strategy in options trading – and one of the most widely used by institutional and retail traders worldwide. If you hold shares of Indian large-cap stocks in your demat account, you can use covered calls to generate a regular monthly income from those holdings, regardless of whether the market goes up, down, or sideways.

This guide explains the covered call strategy with a practical Reliance Industries example, covers which Indian stocks work best, walks through the tax treatment, and shows you how to set it up on Lemonn.

What Is a Covered Call?

A covered call involves two simultaneous positions:

• Long the underlying stock – you already own, or simultaneously buy, at least one lot of the stock.
• Short a call option – you sell one call option (typically OTM) against your stock holding, collecting premium.

The call option is ‘covered’ because you own the underlying shares. If the call is exercised against you, you simply deliver your shares at the strike price – you do not face unlimited loss as a naked call seller would.

The net effect: you receive cash today (the option premium) in exchange for agreeing to sell your shares at the strike price if they rise above it by expiry.

Why Covered Calls Work

Covered calls work because of the basic principle of time decay (Theta). You, as the option seller, collect the Theta that the option buyer pays. As long as the stock stays below your strike price by expiry, the call expires worthless and you keep the entire premium.

This strategy is ideal in three market conditions:

• Sideways markets: The stock goes nowhere; you collect premium as pure income.
• Slightly bullish markets: The stock rises a little; you collect premium plus some upside.
• Slightly bearish markets: The stock dips slightly; the premium partially offsets your loss.

The strategy fails to perform in strong bull runs – your upside is capped at the strike price. This is the fundamental trade-off.

Covered Call Example

You own 500 shares of Reliance Industries at an average cost of Rs.2,800. Current market price: Rs.2,800. Monthly expiry is 25 days away. You sell 1 lot of Reliance Rs.2,900 CE (Call Option) at Rs.50 premium.

Lot size for Reliance (as of 2025): 250 shares. So you sell 2 lots to cover 500 shares.

Premium collected: Rs.50 x 500 = Rs.25,000

Reliance at Expiry	Stock P&L	Option P&L	Net Result
Rs.2,700 (-3.6%)	-Rs.50,000	+Rs.25,000 (call expires worthless, keep premium)	-Rs.25,000 (cushioned by premium)
Rs.2,800 (flat)	Rs.0	+Rs.25,000 (call expires worthless, keep premium)	+Rs.25,000 (pure income)
Rs.2,850 (+1.8%)	+Rs.25,000	+Rs.25,000 (call expires worthless)	+Rs.50,000
Rs.2,900 (+3.6%)	+Rs.50,000	+Rs.25,000 (call at breakeven, keep premium)	+Rs.75,000 (maximum outcome)
Rs.3,000 (+7.1%)	+Rs.100,000	+Rs.25,000 – Rs.50,000 = -Rs.25,000 (call exercised, deliver at 2,900)	+Rs.75,000 (capped – miss Rs.50,000 upside above 2,900)

Key insight: Above Rs.2,900, your profit is capped at Rs.75,000 regardless of how high Reliance goes. If Reliance hits Rs.3,200, you miss Rs.75,000 of additional upside. This is the cost of selling the covered call.

Which Stocks Work Best for Covered Calls?

Not all Indian stocks are suitable for covered call writing. The key criteria:

• Liquid options: Only stocks with F&O-eligible options work. There are approximately 200 stocks in the NSE F&O segment.
• Large-cap, stable stocks: Stocks with lower volatility reduce the risk of a sudden drop. Preferred candidates include Reliance, TCS, Infosys, HDFC Bank, ICICI Bank, Wipro, HUL, ITC.
• Monthly lot sizes manageable: Check the lot size for each stock. HDFC Bank has a lot size of 550 shares, meaning you need 550 shares minimum to write one covered call lot.
• No imminent binary events: Avoid writing covered calls on stocks with result announcements, M&A news, or regulatory decisions due before expiry. These can cause large unexpected moves.
• Higher IV stocks generate more premium: Stocks with higher implied volatility (like BankNifty stocks) generate more premium, but also have larger downside risk.

Setting Up a Covered Call on Lemonn

Step-by-step process on Lemonn’s zero-commission platform:

1. Verify your stock holding: Confirm you own at least one lot’s worth of shares in your demat account (e.g., 250 shares for Reliance).
2. Open the options chain: Navigate to the stock’s options chain on Lemonn. Select the monthly expiry.
3. Select an OTM call strike: Choose a strike 5-8% above the current stock price. For Reliance at Rs.2,800, this means selecting around Rs.2,950 to Rs.3,000.
4. Check the premium: Review the bid price for the call option. Aim for a premium that represents at least 1-2% of the stock price monthly (Rs.28 to Rs.56 on Reliance at Rs.2,800).
5. Place a sell order: Select ‘Sell’ for the call option, enter the number of lots, and place the order at the bid price or use a limit order slightly above the bid.
6. Monitor weekly: Check your position weekly. If the stock approaches your strike with more than 7 days remaining, consider rolling up.

Covered Call Best Practices

Strike selection – the 5-8% OTM rule: Selling strikes 5-8% above the current price strikes a balance between premium income and probability of getting your shares called away. Below 5% OTM and your probability of assignment (having to deliver shares) is too high. Above 8% and the premium is minimal.

Expiry selection – monthly is optimal: Monthly expiries (last Thursday of the month) are preferred over weekly. Weekly covered calls require more active management and the premium per week is lower relative to transaction costs.

IV timing: Sell covered calls when IV is relatively elevated – for instance, just before a quarterly result season begins (premiums are highest when uncertainty is highest). This maximises the premium you collect. Avoid selling calls immediately after a sharp IV collapse.

Rolling up and out: If the stock rallies sharply and approaches your short call strike before expiry, you can ‘roll’ the position: buy back the short call (at a loss) and sell a higher-strike call for the next month, collecting additional credit. This allows you to stay in the trade while giving the stock more room to run.

Risks of Covered Calls

• Capped upside: If the stock rallies significantly above your strike, you miss all gains above the strike. Covered calls are not appropriate for stocks you expect to make very large moves.
• Downside risk unchanged: Covered calls do NOT protect you from a large stock decline. If Reliance falls from Rs.2,800 to Rs.2,200, you absorb the full Rs.600 loss per share. The Rs.50 premium barely cushions it. Covered calls are not a hedging tool for downside risk.
• Assignment risk: If the stock is above your strike at expiry, your shares may be called away. You can repurchase them, but you incur transaction costs and may miss a continued rally.
• Opportunity cost: In strong bull markets, covered call writers consistently underperform simple buy-and-hold investors. The strategy gives up tail-end upside in exchange for steady income.

Covered Call Tax Treatment in India

In India, the tax treatment of covered calls depends on how the positions are classified:

• Option premium received from selling calls is treated as F&O income – non-speculative business income under Section 43(5) of the Income Tax Act.
• This income is added to your total income and taxed at your applicable slab rate (up to 30%).
• If your call gets exercised and you deliver shares, the gain or loss on those shares is treated as capital gains (STCG or LTCG depending on holding period).
• Expenses including STT, brokerage, and exchange charges are deductible from F&O income.
• You must file ITR-3 for any year in which you have option writing income, even if you also have salary income.

Consult a tax professional for your specific situation, particularly if you have a large covered call portfolio alongside long-term equity holdings.
