Basics of Derivatives
Basics of Derivatives
A derivative is a contract or a product whose value is derived from the value of some other asset known as the underlying. Derivatives are based on a wide range of underlying assets.
- Petrol
- Diesel
- Kerosene
- Curd
- Paneer
- Buttermilk
In both examples, the value of the derivative product is linked to the value of the underlying asset. Changes in the underlying asset directly influence the derivative.
Forward Contract
Forward Contract
Essential features of a forward contract are:
- It is a contract between two parties (Bilateral contract).
- All terms of the contract like price, quantity and quality of underlying, delivery terms like place, settlement procedure etc. are fixed on the day of entering into the contract.
Major Limitation of Forward Contracts
Liquidity Risk
Liquidity refers to the ability of the market participants to buy or sell the desired quantity of an underlying asset. As forwards are tailor-made contracts i.e. the terms of the contract are according to the specific requirements of the parties, other market participants may not be interested in these contracts.
Counterparty Risk
Counterparty risk is the risk of economic loss arising from the failure of a counterparty.
Market Participants
Market Participants
1. Hedgers
Entrepreneurs, corporations, investing institutions and banks all use derivative products to hedge or reduce their exposures to market variables such as interest rates, share values, bond prices, currency exchange rates and commodity prices.
2. Traders/Speculators
Try to predict the future movements in prices of underlying assets and based on the view, take positions in derivative contracts. Derivatives are preferred over underlying asset for trading purpose, as they offer leverage, are less expensive (cost transaction is generally lower than that of the underlying) and are faster to execute in size (high volumes market).
3. Arbitrageurs
Originates when a trader purchases an asset cheaply in one location and simultaneously arranges to sell it at a higher price in another location. Such opportunities are unlikely to persist for very long, since arbitrageurs would rush into these transactions, thus closing the price gap at different locations.
Significance of Derivatives
Significance of Derivatives
It helps in improving price discovery based on actual valuations and expectations.
It enables the transfer of various risks from those who are exposed to risk but have a low risk appetite to participants with a high-risk appetite. For example, hedgers want to give away the risk whereas traders are willing to take risk.
It enables the shift of speculative trades from the unorganized market to the organized market. Risk management mechanism and surveillance of activities of various participants in the organized space provide stability to the financial system.

Analogy: Amazon Shopping vs Stock Market
| Amazon Shopping | Stock Market |
|---|---|
| Buyer: Click 'Buy' | Buyer places Buy order |
| Seller: Click 'Sell' (he has the product) | Seller places Sell order (he has the shares) |
| Order details sent to Amazon system | Trade details sent to Clearing Corporation |
| Amazon checks if seller has stock | Depositories confirm seller has shares to Clearing Corporation |
| Product moved to Amazon warehouse | Seller’s shares moved to a pool account (temporary holding) to be ready for delivery |
| Final stock balance check | Depository does a final check to avoid errors and confirms final balance |
| Amazon adjusts orders/returns (netting) | Clearing Corp nets out broker’s trades. Example: Buy 1,000 shares, Sell 600 shares = only 400 need to be settled |
| Buyer pays and gets delivery | Funds and shares exchanged (Pay-in/Pay-out). On settlement day (T+1 or T+2): Buyers’ brokers pay money; Sellers’ brokers deliver shares |
| Amazon: 'Order delivered successfully’ | Clearing & Settlement completed. Clearing Corporation ensures money goes to sellers and shares go to buyers |
| Amazon is middleman between buyer and seller | Clearing Corp acts as counterparty (Novation) |
| If seller fails, Amazon finds another seller/refunds | If seller defaults, Clearing Corp holds auction/compensates. If seller fails, Clearing Corporation buys shares from the market (auction) or compensates the buyer |

Meaning of Margin
Meaning of Margin
Margin is the sum that is blocked from our account when we open a derivatives position. Formula
Components of Initial Margin
SPAN Margin
SPAN (Standard Portfolio Analysis of Risk) Think of it as a risk calculator used worldwide. It looks at your entire portfolio and figures out: “If the market moves badly tomorrow, how much can you lose?” Based on this, it decides how much margin (deposit) you must keep.
Exposure Margin
This adds an extra buffer-against sudden, wild swings. For stock futures and option selling, it’s approximately 3.5% of the contract value. For index derivatives, it's around 2-3%.
Example (Nifty Futures, Lot Size = 75)
Day 1: Entry
Buy Nifty futures at ₹17,800. Contract value = ₹17,800 × 75 = ₹13.35 lakh.
Margin blocked (say 12%) = ₹1.6 lakh.
Closing price = ₹18,000.
Gain = (18,000 – 17,800) × 75 = ₹15,000.
Profit added → Margin balance rises to ₹1.75 lakh.
Day 2
Reference = 18,000. Closing = ₹17,900.
Loss = (17,900 –18,000) ×75 = -₹7,500.
Loss deducted → Margin balance falls to ₹1.675 lakh.
Day 3
Reference = 17,900. Closing = ₹18,100.
Gain = (18,100 – 17,900) × 75 = ₹15,000.
Profit added → Margin balance becomes ₹1.825 lakh.
Futures Pricing
The Cash and Carry Model explains that the futures price equals the spot price plus the cost of carry minus any income from the asset (like dividends).
F = Futures Price
S = Spot Price
This is the basic version, used when costs/income are expressed in rupee terms or using simple interest.

Question 1
Which of the following statements best distinguishes a forward contract from a futures contract?
- Forwards are standardized contracts traded on exchanges, while futures are private agreements traded over-the-counter.
- Forwards settle gains/losses only at maturity, whereas futures are marked-to-market daily with margins.
- Forwards carry minimal credit risk due to clearinghouse guarantees, whereas futures have high counterparty default risk.
- Forwards require an initial margin deposit, while futures typically require no upfront payment.

Question 2
Suppose the spot price of a stock index is ₹10,000. The risk-free interest rate is 6% per annum. Assume no dividends on the index and no other holding costs or benefits. What is the fair futures price for a contract expiring in 6 months (0.5 year), based on the cost-of-carry model? (Use simple interest for approximation.)
- ₹10,000
- ₹10,300
- ₹10,600
- ₹10,700
View Solution
Question 3
Mr. Sharma shorts 1 lot of XYZ futures at ₹200 per unit. Each lot represents 100 units. Later, he closes (squares off) his position at ₹180 per unit. What is Mr. Sharma’s profit or loss on this futures trade (ignoring transaction costs)?
- ₹2,000 profit
- ₹2,000 loss
- ₹20 profit
- ₹20 loss
View Solution
• A short futures position profits when prices fall.
• Mr. Sharma sold at ₹200 and bought back at ₹180, gaining ₹20 per unit. With a lot size of 100 units, his total profit = ₹20 × 100 = ₹2,000. This is a realized profit added to his account.
Question 4
If a trader’s futures position incurs losses such that the funds in the margin account fall below the required maintenance margin level, what typically happens?
- The trader will receive a margin call to deposit additional funds to restore the margin to the initial level.
- The position is automatically terminated by the exchange with no further action.
- The trader can continue to hold the position until expiry without adding funds.
- The losses are ignored as long as the trader has paid initial margin once.

What are OPTIONS?
What are OPTIONS?
A Contract that:
- Gives the buyer the right, but not the obligation; To buy or sell a specified underlying asset; at a set price on or before a specified date
Types of OPTIONS Contract
| Buyer | Seller |
|---|---|
|
CALL Has the right to buy a stock at specified price |
CALL Has the obligation to sell a stock at a specified price |
|
PUT Has the right to sell a stock at specified price |
PUT Has the obligation to buy a stock at specified price |
Options Terminology
These options have a stock index as the underlying asset. For example, Options on Nifty, Sensex, etc.
These options have individual stocks as the underlying asset. For example, Option on ONGC, NTPC, etc.
The owner (buyer/holder) of an American Option can exercise his right at any time on or before the expiry date/day of the contract.
The owner (buyer/holder) of a European Option can exercise his right only on the expiry date/day of the contract. In India, all Index and Stock Options are European Style Options.
It is the price which the option buyer pays to the option seller.
It is the price at which the underlying asset is trading in the spot market. In our examples, it is the value of underlying index (Nifty 50) which was 18315.10 at that point of time.
Strike price is the price per share for which the underlying security may be purchased by the call option holder (or sold by the put option holder). In our examples, strike price for both call and put options is 18400.
Moneyness of an Option
In-the-money (ITM) Option
This option would give the option holder a positive cash flow, if it were exercised immediately. A call option is said to be ITM, when spot price is higher than strike price. A put option is said to be ITM when spot price is lower than strike price. In our examples, the put option is in-the-money.
At-the-money (ATM) Option
At-the-money option would lead to zero cash flow if it were exercised immediately. Therefore, for both call and put ATM options, strike price is equal to spot price. In reality, because the strike prices are at fixed intervals of say, Rs.5, Rs.10 or Rs.50, while the spot price moves in much smaller increments, the two prices may rarely be equal. Hence an ATM option can be defined as an option with a strike price which is closest to the spot price.
For example, if the index is at 18415 and three options on the index with strike prices of 18350, 18400 and 18450 are available for trading, the option with the strike price of 18400 is an ATM option.
Out-of-the-money (OTM) Option
An out-of-the-money option is one with a strike price worse than the spot price for the holder of option. In other words, this option would give the holder a negative cash flow if it were exercised immediately.
An out-of-the-money option is one with a strike price worse than the spot price for the holder of option. In other words, this option would give the holder a negative cash flow if it were exercised immediately. A call option is said to be OTM, when spot price is lower than strike price. A put option is said to be OTM when spot price is higher than strike price. In our examples, the call option is out-of-the-money.
Call Option – Right to Buy & Put Option – Right to Sell
Call Option – Right to Buy & Put Option – Right to Sell
Call Option – Right to Buy
A Call option gives the buyer the right (not obligation) to buy an asset at a fixed price (called Strike Price) before/at expiry.
The seller (writer) of the call is obligated to sell if the buyer chooses to exercise.
The buyer pays a Premium to the seller.
Premium is like a booking fee.
Call Buyer (Right to Buy at ₹1,500. Premium ₹50)
- Loss is limited to premium (₹50) → flat line below zero.
- Profit starts after ₹1,550 (Strike + Premium = Breakeven Price) and grows unlimited as stock price rises.
Put Option – Right to Sell
A Put Option gives the buyer the right (not obligation) to sell an asset at strike price before/at expiry.
The seller (writer) of the put must buy if the buyer exercises.
Buyer pays premium, risk is limited, and the seller receives the premium.
Buying a Put Option Profitability depends on the Concept of Selling High at price and Buying at a Low price.
Put Buyer (Right to Sell at ₹1,700, Premium ₹40)
- Loss is limited to premium (₹40) → flat line below zero.
- Profit starts after ₹1,660 (Strike Premium = Break even) and increases as stock price falls.
In Short
| Call Option | Put Option |
|---|---|
| Call Buyer = Spot Price > Strike Price = Intrinsic Value | Put Buyer = Spot Price < Strike Price = Intrinsic Value |
| Intrinsic Value = Spot Price – Strike Price | Intrinsic Value = Strike Price – Spot Price |
| Example: Strike Price is Rs. 100; Spot Price is Rs. 200 | Example: Strike Price is Rs. 100; Spot Price is Rs. 50 |
| Intrinsic Value = 200 - 100 = Rs. 100 | Intrinsic Value = 100 - 50 = Rs. 50 |
| Assume Premium Paid by the Call Buyer is Rs. 20 | Assume Premium Paid by the Put Buyer is Rs. 20 |
| Profit =Rs. 100 –Rs. 20 = Rs. 80 | Profit =Rs. 50 –Rs. 20 =Rs. 30 |
| Break-even Price = Rs. 100 + Rs. 20 = Rs. 120 (Strike Price + Premium) | Break-even Price = Rs. 100 - Rs. 20 = Rs. 80 (Strike Price – Premium) |
| For a Call Seller, the maximum gain is the premium received, but loss is unlimited. | For a Put Seller, the maximum gain is the premium received (Rs. 20), but loss is unlimited. |
