What is an Options Contract? A Simple Guide for Indian Traders
An options contract gives the buyer the right, but not the obligation, to buy or sell an asset at a fixed price before expiry. The buyer pays a premium for this right. The seller receives the premium and takes on the obligation if the buyer chooses to use the option.
Options are the second main derivative in India, and they work differently from futures. With an option, the buyer has a choice, not a compulsion.
This single feature, the right without the obligation, makes options flexible and popular. Let us unpack it with a real example and the points that matter. You can trade options on Stockk.
Key Takeaways
- An option gives the buyer a right, not an obligation, to trade at a set price.
- The buyer pays a premium; the seller receives it.
- A call option is the right to buy; a put option is the right to sell.
- The buyer's risk is limited to the premium paid.
- The seller takes on larger, sometimes open-ended, risk.
What are calls and puts?
Every option is either a call or a put:
- Call option: the right to buy at the strike price, used when you expect a rise
- Put option: the right to sell at the strike price, used when you expect a fall
Take the case where HDFC Bank trades at ₹1,650 and you buy a ₹1,700 call for a ₹20 premium. If the stock rises above ₹1,720, your call becomes profitable. If it stays below ₹1,700, the most you lose is the ₹20 premium.
Why is the buyer-seller relationship unequal?
The buyer and seller of an option do not carry equal risk. This is the most important idea in options.
| Side | Pays or receives | Risk |
|---|---|---|
| Buyer | Pays premium | Limited to premium |
| Seller | Receives premium | Large or open-ended |
The buyer risks only the premium, but needs a move that is both large enough and fast enough, because time decay works against the position every day. The seller keeps the premium if the option expires worthless, but can face large losses if the market moves sharply against them.
How is an option different from a future?
A future obligates both sides to trade at expiry. An option gives the buyer a choice. Option buyers also have limited risk, while futures carry linear, open-ended risk. Finally, options cost a premium upfront.
| Feature | Options | Futures |
|---|---|---|
| Obligation | Buyer has a choice | Both sides obligated |
| Buyer risk | Limited to premium | Open-ended |
| Upfront cost | Premium | Margin |
| Payoff | Bends at the strike | Straight line |
Why are options so flexible?
Options let you shape your risk in ways shares and futures cannot. You can profit from a rise, a fall, or even a market that stays still. You can also combine calls and puts to build strategies that fit a precise view.
- Bullish view: buy a call for limited risk, or sell a put to collect premium while accepting open-ended risk
- Bearish view: buy a put for limited risk, or sell a call to collect premium while accepting open-ended risk
- Neutral view: sell both a call and a put to earn from time decay in a quiet market, accepting risk on both sides
- Protection: buy a put to insure shares you already hold, or sell a call against them for income, which caps the upside
What happens at expiry?
If an option has no value at expiry, it expires worthless and the buyer loses the premium. If it has value, it is settled for that amount. Most Indian index options are cash-settled, while many stock options settle by physical delivery.
Stockk, run on Indira Securities, gives you access to options in one place. Start by opening a demat account, then explore F&O tools and the Knowledge Center.
Futures and Options are leveraged products and carry a high risk of loss that can be more than the money you put in. This article is only for learning and is not a recommendation to trade in derivatives.
Frequently Asked Questions
What is the difference between an option and a future?
A future obligates both parties to transact at expiry, while an option gives the buyer a choice. Option buyers have limited risk; futures have open-ended risk. Options also cost a premium upfront.
What happens if my option expires worthless?
If the option has no value at expiry, the buyer loses the full premium and the seller keeps it. This is the most common outcome for out-of-money options.
Can I sell an option without buying one first?
Yes. Selling or writing an option to open a position collects premium upfront, but it carries the obligation and needs higher margin. Naked selling can lead to large losses.
Are options cheaper than futures?
Buying an option costs only the premium, usually smaller than futures margin. But options can expire worthless, while futures keep moving with price.
How do I choose between a call and a put?
Buy calls when you expect a rise and puts when you expect a fall. Strike and expiry then shape the risk and reward.
