What Are Options in the Stock Market
Options trading uses call and put contracts linked to an underlying asset. Before trading, you should understand premium, strike price, expiry and possible loss.
- There are 2 basic option types: calls and puts.
- Buyers pay a premium to enter an options position.
- A buyer can lose the entire premium paid.
- Option writers can face losses greater than the premium received.
- Time decay, volatility and liquidity can affect option prices.
- Beginners can understand the process through 4 basic trading steps.
Understanding the payoff, break-even point, and maximum loss before entering a position can help you assess options trading risk more clearly.
What is options trading?
Options trading involves buying or selling derivative contracts linked to an underlying asset, such as a share or stock market index.
An option buyer receives a right under the contract. The seller, also called the option writer, takes the corresponding obligation.
The buyer pays an amount called the option premium. Each contract also has a strike price and an expiry date.
There are 2 main types of options:
| Option type | Right given to the buyer | Common market view |
| Call option | Right to buy the underlying asset at the strike price | Price may rise |
| Put option | Right to sell the underlying asset at the strike price | Price may fall |
You can read more about the basic mechanism of options trading before assessing individual strategies.
Unlike buying a share directly, an option can lose value even when the underlying price does not move sharply against you. Time remaining until expiry and changes in volatility also influence the premium.

How do call and put options work?
Put options and call options create different payoff structures for buyers and sellers.
| Position | What the trader does | Primary risk |
| Buy a call | Pays premium for the right to buy | Full premium can be lost |
| Buy a put | Pays premium for the right to sell | Full premium can be lost |
| Sell a call | Receives premium and takes an obligation | Loss can exceed premium received |
| Sell a put | Receives premium and takes an obligation | Loss can become substantial if the underlying falls |
For a long call, the break-even price at expiry can be expressed as:
Call break-even = Strike price + Premium paid
For a long put:
Put break-even = Strike price − Premium paid
These figures exclude brokerage, taxes and other transaction charges.
Consider an illustrative example. Rohan is 29 years old, lives in Jaipur and earns ₹45,000 per month. He wants to understand the payoff of a hypothetical call option before considering derivatives.
Assume:
- Strike price: ₹500 per unit
- Premium: ₹20 per unit
- Illustrative lot size: 50 units
- Expiry price of underlying: ₹550 per unit
The premium paid is:
₹20 × 50 units = ₹1,000
The intrinsic value at expiry is:
₹550 − ₹500 = ₹50 per unit
Total expiry value is:
₹50 × 50 units = ₹2,500
Gross result before charges is:
₹2,500 − ₹1,000 = ₹1,500
If the underlying finishes at or below the ₹500 strike price at expiry, this call buyer can lose the full ₹1,000 premium.
The 50-unit lot is used only for illustration. Actual market lot sizes depend on the contract specified by the exchange.
What risks should beginners understand before options trading?
A beginner should first understand that options trading can result in the complete loss of the premium paid, while some option-selling positions can create substantially larger losses.
The Securities and Exchange Board of India (SEBI) found that 87.7% of individual options traders were loss-making in FY26. The figure covers individual options traders studied by SEBI and is not limited to beginners.
Important risks include:
- Premium loss: An option buyer can lose the full premium paid if the contract expires without sufficient value.
- Option-writing risk: A seller's loss can exceed the premium collected when the market moves sharply against the position.
- Time decay: An option's time value reduces as expiry approaches when other pricing factors remain unchanged.
- Volatility risk: A change in expected volatility can increase or reduce the premium.
- Liquidity risk: A wider bid-ask spread can increase trading cost and affect execution.
- Margin risk: Option writers must maintain applicable margins. Additional margin requirements can arise when market conditions change.
- Expiry risk: Open contracts are subject to the exchange's settlement rules when they reach expiry.
SEBI's risk disclosure framework also warns that an option holder can lose the entire amount paid within a relatively short period.

How to trade options in four steps?
Options trading involves choosing a contract, understanding its risk and checking the applicable expiry and margin requirements before placing an order.
Before entering options trading, it also helps to understand the difference between derivatives through this guide to futures and options trading.
Step 1: Enable the F&O segment
You need a trading account with the Futures and Options (F&O) segment enabled.
Stock brokers must maintain documentary evidence of financial information for clients who opt to trade in the derivatives segment. The supporting document can depend on the applicable onboarding requirements.
Step 2: Decide between a call and put
Select the option according to the position you intend to take.
Buying and selling the same type of option produce different payoff and risk structures. A market view alone is therefore not enough to choose the position.
Step 3: Select the strike price and expiry
Check the strike price, expiry date, premium, lot size and available liquidity.
As of 30 October 2026, National Stock Exchange of India (NSE) equity-derivative contracts covered by its current specifications use Tuesday as the relevant expiry day. If that Tuesday is a trading holiday, the previous trading day applies.
Do not assume that a shorter expiry means a faster profit. Less time remaining until expiry increases the importance of time decay for an option buyer.
Step 4: Check maximum loss and exit conditions
Calculate the amount at risk before submitting the order.
For an option buyer, this includes the total premium and transaction costs. For an option writer, assess margin requirements and the loss that can arise from an adverse movement.

What does options trading cost?
Options trading costs include the premium for buyers, brokerage and applicable statutory or exchange charges.
| Cost | How it applies | Why it matters |
| Option premium | Paid by the buyer | Entire premium can be lost |
| Brokerage | Depends on the broker's tariff | Reduces the net trading result |
| Securities Transaction Tax (STT) | Applies to specified transactions | Rate depends on the transaction type |
| Exchange and regulatory charges | Apply as prescribed | Add to total transaction cost |
| Goods and Services Tax (GST) | Applies to eligible service charges | Increases the final cost |
| Stamp duty | Applies according to prevailing rules | Adds to transaction expenses |
From 1 April 2026, STT on the sale of an option in securities is 0.15% of the option premium, payable by the seller. For an option that is exercised, the applicable STT is 0.15% of the intrinsic value, payable by the purchaser.
These charges affect break-even calculations. A position that shows a gross profit before charges can produce a lower net profit after all applicable costs.

What are the advantages and disadvantages of options?
Options can create defined payoff structures and support hedging, but they also introduce expiry, pricing and margin risks.
| Aspect | Advantage | Disadvantage |
| Buyer risk | Maximum contractual loss on a basic long option is limited to the premium paid | The full premium can still be lost |
| Hedging | Put options can protect an existing market exposure | The hedge requires payment of a premium |
| Upfront amount | An option buyer pays a premium rather than the full value of the underlying asset | A smaller upfront amount does not mean a smaller percentage loss |
| Strategy choice | Calls and puts can be combined into different payoff structures | Multi-leg positions require greater understanding of pricing and execution |
| Expiry | Contracts have a defined expiry date | Time decay can work against the buyer |
| Option writing | Writer receives the premium | Loss can exceed the premium received |
Options are therefore different from direct equity investing. Buying cash equity gives ownership of shares, while an option is a time-bound derivative contract.
Futures are another derivative category, but futures create obligations for both sides rather than giving the buyer the same type of contractual right as an option.
How can beginners manage options trading risk?
Beginners can manage options trading risk by defining the maximum acceptable loss before entering a position and checking how premium, expiry and volatility affect that loss.
A practical checklist includes:
- Know the payoff: Write down what happens if the underlying rises, falls or remains near the same price.
- Calculate the premium at risk: For a long option, multiply the premium per unit by the contract quantity.
- Check the break-even point: Include the premium and applicable transaction costs.
- Review time to expiry: Understand how a shorter remaining period changes the role of time decay.
- Check liquidity: Compare the available bid and ask prices before placing the order.
- Understand writing obligations: Do not treat premium received from selling an option as profit without considering margin and downside exposure.
- Avoid using borrowed household money: Derivative losses should not affect money required for essential expenses or near-term financial commitments.
A common beginner objection is that buying an option appears less costly than buying the underlying shares. The smaller initial premium does not remove risk. A buyer can lose 100% of the premium paid if the position does not work before expiry.
Conclusion
Options trading uses call and put contracts with defined strike prices and expiry dates, but the financial outcome remains uncertain. Buyers can lose the full premium, while option writers can face greater losses.
Before assessing an options position, understand the payoff, break-even level, expiry, time decay, liquidity and applicable costs. These factors provide a clearer basis for evaluating options trading than relying only on a view that the market will rise or fall.

Frequently Asked Questions
Options Trading for Beginners
Can I lose more than the premium when I buy an option?
For a basic long call or long put, your contractual loss is limited to the premium paid for the option. Transaction charges also add to your total cost. The entire premium can become worthless by expiry if the contract does not retain sufficient value. This loss structure is different from option writing, where the seller takes an obligation and can face a loss greater than the premium received.
Is option buying safer than option selling?
Option buying and option selling have different risk structures. A basic option buyer knows that the contractual loss is limited to the premium paid, while an uncovered option writer can face a much larger loss. This does not make option buying low-risk. An option buyer can still lose the entire premium within a short period because of price movement, time decay or changes in volatility.
Are options trading suitable for beginners?
Options trading requires an understanding of premium, strike price, expiry, lot size, volatility, liquidity and payoff. Beginners should understand these concepts before assessing whether derivatives fit their objectives and financial circumstances. SEBI's FY26 study found that 87.7% of individual options traders incurred losses, which shows why risk understanding should come before deciding whether to participate.
Why does an option lose value when the market moves my way?
An option premium depends on more than the direction of the underlying asset. Time remaining until expiry and changes in expected volatility also affect its price. For example, a call option can lose value when the underlying rises only slightly but time value falls sharply. This is why predicting direction alone does not determine whether an option position earns a profit.
What happens when an option expires?
The outcome depends on the contract, whether it finishes in or out of the money and the applicable exchange settlement mechanism. Open positions cease after expiry and eligible in-the-money options are handled under the exchange's settlement rules. You should therefore check the current contract specifications and settlement obligations before carrying an option position into its expiry day.
How much money do I need for options trading?
There is no single amount that applies to every options trade. For a buyer, the required amount depends mainly on the premium, lot size and number of contracts, along with applicable charges. Option writers need applicable margin rather than only the premium amount. The required amount therefore changes with the contract, market conditions and the type of options position.
