How Does Options Trading Work?
Options trading works through standardised contracts on NSE (National Stock Exchange) that give the buyer the right (but not obligation) to buy or sell an underlying asset at a predetermined strike price on or before the expiry date. The buyer pays a premium for this right; the seller receives the premium and must fulfil the contract if the buyer exercises it. Most Indian options are settled in cash (difference between spot price and strike price), not by actual delivery of shares.
Step-by-Step: How an Options Trade Works
- Choose the underlying asset: Nifty 50, Bank Nifty, or individual stocks like Reliance.
- Select option type: Call (if you expect price to rise) or Put (if you expect price to fall).
- Choose strike price: The price at which you have the right to buy (call) or sell (put).
- Select expiry: Weekly (Nifty/BankNifty expires every Thursday) or monthly (last Thursday of month).
- Pay the premium: The option buyer pays the premium; this is the maximum loss for a buyer.
- Monitor: Track the option value as it fluctuates based on the underlying's movement and time to expiry.
- Exit or let expire: Sell the option before expiry to book profit or loss, or let it expire (worthless if out-of-the-money).
Practical Options Example
Nifty is at 22,000. You buy a 22,200 Call option expiring in one week for a premium of Rs 50 per unit. Lot size: 25 units. Total premium paid: Rs 50 x 25 = Rs 1,250.
- If Nifty rises to 22,400 before expiry, the option value increases to approximately Rs 200+. Profit: (200 - 50) x 25 = Rs 3,750.
- If Nifty stays at 22,000 at expiry, the option expires worthless. Loss: Rs 1,250 (full premium).
- Maximum loss is always limited to the premium paid (Rs 1,250 in this example).
Key Terms in Options Trading
| Term | Meaning |
|---|---|
| In-the-money (ITM) | Option has intrinsic value; call: spot > strike; put: spot < strike |
| At-the-money (ATM) | Strike price is at or near the current spot price |
| Out-of-the-money (OTM) | Option has no intrinsic value; only time value |
| Intrinsic value | The profit if exercised immediately |
| Time value | Premium above intrinsic value; decays to zero at expiry (theta decay) |
Key Takeaway
Options trading provides leveraged exposure with limited risk for buyers and regular premium income for sellers. The mechanics involve choosing the right direction, strike, and expiry to profit from market moves. However, time decay works against buyers every day, making options trading challenging for untrained participants.
