If you’ve spent any time on Indian financial social media, you’ve seen the screenshots: ₹500 turned into ₹50,000 on a single options trade. What you don’t see are the thousands of accounts that went to zero on the same day. SEBI’s landmark 2023 study found that 89% of individual F&O traders in India lost money between FY22 and FY24, with average losses of ₹1.1 lakh per person per year.
This guide doesn’t promise to make you profitable in options. It gives you the foundational knowledge to understand what options are, how they work in the Indian market context, and why they’re structurally unsuitable for most retail traders.
What is an option?
An option is a contract that gives the buyer the right, but not the obligation, to buy or sell an underlying asset at a predetermined price (strike price) on or before a specific date (expiry). The buyer pays a premium for this right. The seller (writer) collects the premium and takes on the obligation.
In India, equity options are traded on NSE and BSE. The most liquid options are on:
- Nifty 50 index — weekly expiry (Thursday), most liquid
- Bank Nifty index — weekly expiry (Wednesday)
- FinNifty index — weekly expiry (Tuesday)
- Stock options — monthly expiry (last Thursday), on ~175 stocks
Call options vs put options
Call option (CE)
A call option gives the buyer the right to buy the underlying at the strike price. You buy a call when you expect the price to go up.
Example: Nifty is at 24,500. You buy the 24,600 CE (call) expiring this Thursday for a premium of ₹80. If Nifty closes at 24,750, your option is worth ₹150 (24,750 − 24,600). Profit = ₹150 − ₹80 = ₹70 per unit. Lot size is 25 units, so profit = ₹1,750.
If Nifty closes below 24,600, the call expires worthless. Your maximum loss is the premium paid: ₹80 × 25 = ₹2,000.
Put option (PE)
A put option gives the buyer the right to sell the underlying at the strike price. You buy a put when you expect the price to go down.
Example: Nifty is at 24,500. You buy the 24,400 PE (put) for ₹70. If Nifty drops to 24,200, your put is worth ₹200 (24,400 − 24,200). Profit = ₹200 − ₹70 = ₹130 per unit = ₹3,250 on one lot.
If Nifty stays above 24,400, the put expires worthless. Maximum loss = ₹70 × 25 = ₹1,750.
Key terminology
- Strike price: The predetermined price at which the option can be exercised. Nifty options have strikes at every 50-point interval (24,400, 24,450, 24,500, etc.).
- Premium: The price paid by the buyer to the seller for the option contract. Determined by intrinsic value + time value.
- Expiry: The date on which the option contract ceases to exist. Index options have weekly expiries; stock options are monthly.
- ITM (In The Money): Call with strike below current price, or put with strike above current price. Has intrinsic value.
- OTM (Out of The Money): Call with strike above current price, or put with strike below current price. No intrinsic value — only time value.
- ATM (At The Money): Strike price equals (or is closest to) the current market price.
- Lot size: Options are traded in lots, not individual units. Nifty lot size is 25 units. Bank Nifty is 15 units (revised by SEBI in 2024).
SEBI’s F&O study: the numbers nobody wants to hear
In January 2024, SEBI published an updated study on F&O profitability. The findings:
- 89% of individual traders in equity F&O incurred net losses in FY24
- Average loss per loss-maker: ₹1.1 lakh per year
- Only 11% made profits, with average profit of ~₹1.5 lakh
- The top 3.5% of profitable traders accounted for most of the profit pool
- Transaction costs (brokerage + STT + exchange charges + GST) consumed 28% of gross trading turnover for the median retail trader
- Retail traders collectively lost ₹75,000+ crore in F&O in FY24
SEBI responded by increasing margin requirements, restricting weekly expiries to one per exchange, and raising contract sizes. These measures reduce leverage but don’t change the structural disadvantage retail traders face against algorithmic and institutional participants.
The four basic option strategies
1. Long call (bullish)
Buy a call option. Maximum loss = premium paid. Maximum profit = unlimited (theoretically). Breakeven = strike + premium.
When to use: You expect a significant upward move before expiry. “Significant” means the move must exceed the premium paid — a small move still results in a loss.
Indian context: Buying weekly OTM calls on Nifty is the most common retail trade and the most common way to lose money. The premium decays fast (theta), and you need a large directional move within days to profit.
2. Long put (bearish)
Buy a put option. Maximum loss = premium paid. Maximum profit = strike price minus premium (underlying can’t go below zero). Breakeven = strike − premium.
When to use: You expect a significant downward move, or you want to hedge an existing long stock position.
Indian context: Puts are less liquid than calls on most stock options. Index puts (Nifty, Bank Nifty) have good liquidity and are commonly used for portfolio hedging.
3. Covered call (mildly bullish to neutral)
Own the stock (or futures equivalent) and sell a call option against it. You collect premium income but cap your upside at the strike price.
When to use: You hold a stock and expect it to stay flat or rise slightly. The premium collected provides additional return on top of dividends.
Indian context: Covered calls work well on low-volatility large-caps like HDFC Bank, Infosys, or ITC. The lot size requirement means you need to hold the full lot equivalent in stock (e.g., 550 shares of Infosys for one lot).
4. Protective put (insurance)
Own the stock and buy a put option to protect against downside. You pay a premium for downside protection while retaining unlimited upside.
When to use: You hold a stock with unrealised gains and want to protect against a correction without selling (which would trigger capital gains tax). Think of it as an insurance premium.
Indian context: Useful around budget, election results, or earnings seasons when volatility spikes. The premium cost typically runs 2–4% of the position value for a 1-month put.
Option Greeks simplified
Greeks measure how an option’s price changes with respect to different factors. You don’t need a PhD to use them — but you need to understand two:
Delta
Delta measures how much the option price moves for a ₹1 move in the underlying.
- ATM call delta ≈ 0.5 (option moves ₹0.50 for every ₹1 Nifty move)
- Deep ITM call delta → 1.0 (moves almost 1:1 with underlying)
- Far OTM call delta → 0.05 (barely moves; this is the “lottery ticket” option)
- Put delta is negative (−0.5 for ATM put)
Practical use: If you buy a Nifty 24,500 CE with delta 0.5 and Nifty moves up 100 points, your option premium increases by approximately ₹50. Delta tells you your directional exposure.
Theta
Theta measures how much premium the option loses per day due to time decay, all else being equal.
- ATM options have the highest theta — they lose the most value per day
- Theta accelerates as expiry approaches (non-linear decay)
- Weekly options lose premium aggressively — an ATM Nifty weekly option might lose ₹10–15/day on Monday, ₹25–30/day by Wednesday
- Option buyers fight theta; option sellers benefit from it
Practical use: If you buy a weekly option on Monday morning and Nifty doesn’t move by Wednesday afternoon, you’ve likely lost 40–60% of your premium to theta alone. This is why most weekly option buyers lose — the underlying must move enough and fast enough to overcome time decay.
Why options are NOT for beginners
Despite the marketing from brokers (who earn per trade regardless of your P&L), options trading has structural characteristics that work against beginners:
- Asymmetric information: Institutional traders have superior models, faster execution, and access to order flow data. The retail trader is almost always the less-informed participant.
- Time decay is a constant headwind: Option buyers lose money every second the underlying doesn’t move in their favour. You’re paying rent on your position.
- Leverage amplifies losses: A ₹2,000 premium position on Nifty controls ₹6+ lakh of notional value. The perceived “limited risk” of buying options masks the reality that you’re making leveraged bets.
- Transaction costs compound: STT on options exercise is 0.0625% of settlement value (not premium). Frequent trading racks up brokerage, GST on brokerage, exchange charges, and SEBI turnover fees. These costs are invisible in screenshots but devastate actual returns.
- Psychological toll: Watching a ₹5,000 premium bleed to ₹500 over 3 days creates the impulse to “average down” or “revenge trade” — behaviours that accelerate losses.
If you still want to learn options
After understanding the risks, if you choose to explore options, here’s the progression path that minimises damage:
- Paper trade for 3 months minimum. Use Sensibull or Opstra to simulate trades without real capital. Track every trade in a journal.
- Start with covered calls only. You already own the stock; selling calls generates income. This is the lowest-risk options strategy.
- Never risk more than 2% of capital on a single trade. If your trading capital is ₹5 lakh, maximum premium at risk per trade = ₹10,000.
- Avoid weekly OTM options entirely for the first year. The fast decay and wide bid-ask spreads are designed to transfer money from retail to institutions.
- Learn to sell options (with defined risk). Strategies like iron condors and credit spreads let you benefit from theta instead of fighting it. But these require higher capital and understanding of margin requirements.
Margin requirements in India
SEBI mandates upfront margin collection for all F&O positions:
- Option buying: Full premium must be paid upfront. No leverage on buying. A ₹100 premium × 25 lot = ₹2,500 to enter the trade.
- Option selling: Requires SPAN margin + exposure margin, typically ₹1–1.5 lakh for one lot of Nifty options. This is the capital-intensive side.
- Peak margin reporting: SEBI requires brokers to report intraday peak margins. Margin shortfall results in penalties for both broker and client.
The bottom line
Options are powerful instruments — for hedging, for income generation on existing positions, and for expressing nuanced market views. They are not a way to get rich quick with ₹2,000. The math is clear: 89% of individual F&O traders lose money in India. The edge belongs to those with superior information, technology, capital, and emotional discipline.
If you’re a beginner investor, spend your first 2–3 years building a portfolio of quality stocks and mutual funds. Learn options theory. Paper trade. Only allocate real capital to options after you’ve proven to yourself — with tracked results — that you can be profitable in simulation.
