An option is a contract that gives the buyer the right — but not the obligation — to buy (Call) or sell (Put) an underlying asset at a specified price (strike price) on or before expiry. The buyer pays a premium; the seller (writer) receives it and takes on the obligation.
Options are powerful tools for hedging portfolios, generating income (by selling), or making leveraged directional bets with defined risk (by buying).

Risk Warning
Options are complex leveraged instruments. Short (written) call options carry unlimited loss potential; short puts carry substantial risk. Never risk more than you can afford to lose, and always use stop-losses.

Pro Tip: Use Options for Hedging
Buying put options on your equity holdings acts like portfolio insurance — if markets fall sharply, your puts gain value and offset losses in your stock portfolio. The premium paid is the cost of this insurance.
Frequently Asked Questions
A call option gives the buyer the right (not obligation) to buy the underlying asset at the strike price before expiry. A put option gives the buyer the right to sell. Call buyers profit when the price rises; put buyers profit when the price falls. Option sellers (writers) collect the premium and take the opposite side of the trade.
For a Long Call: Break-even = Strike Price + Premium Paid. For a Long Put: Break-even = Strike Price − Premium Paid. For Short Call: Break-even = Strike Price + Premium Received. For Short Put: Break-even = Strike Price − Premium Received. At the break-even spot price, your P&L is exactly zero at expiry.
Yes. If a call option expires with the spot price below the strike price (out-of-the-money), or a put option expires with spot above strike, the option expires worthless. The buyer loses the entire premium paid. Studies suggest 70–80% of options expire worthless, which is why option selling (writing) is a popular strategy — though it carries higher risk.
When buying (going long) options, your maximum loss is limited to the premium paid. If you buy a call at ₹50 premium with a lot size of 50, your maximum loss is ₹50 × 50 = ₹2,500 per lot. This limited-loss feature makes long options attractive for hedging and directional bets with defined risk.
F&O trading income in India is treated as business income (not capital gains), regardless of holding period. It must be reported under 'Profits and Gains from Business or Profession' in your ITR. You can deduct trading expenses (brokerage, STT, etc.) against this income. Losses from F&O can be set off against other business income and carried forward for 8 years, but only if you file ITR on time.
