📚 1. Basics of Derivatives
A derivative is a financial contract whose value is derived from an underlying asset. Think of it like a bet between two parties on the future price of something — it could be gold, wheat, shares, or even an index like Nifty 50.
1.1 Underlying Assets
Derivatives can be based on many types of assets. Here are the main categories:
| Category | Examples | Description |
|---|---|---|
| Metals | Gold, Silver, Copper | Precious and industrial metals traded on commodity exchanges |
| Energy | Crude Oil, Natural Gas | Energy commodities with significant price volatility |
| Agricultural | Wheat, Cotton, Sugar | Farm produce where hedging protects farmers from price drops |
| Financial | Shares, Bonds, Currencies, Indices | Most actively traded derivatives in India are equity-based |
1.2 History & Evolution
- 12th Century: Earliest forward contracts appeared in European trade fairs for merchants dealing in goods
- 1848: Chicago Board of Trade (CBOT) was established — the first modern commodity exchange
- 1973: Black-Scholes model revolutionised option pricing, making options more accessible
- Modern Era: Electronic trading, algorithmic strategies, and global integration have transformed derivatives markets
1.3 Indian Market History
Key Milestone: The L.C. Gupta Committee (1998) recommended introducing derivatives trading in India. SEBI then approved derivatives as “securities” under the Securities Contract Regulation Act (SCRA), 1956. NSE launched index futures (Nifty 50) on June 12, 2000.
- June 2000: Index futures launched on NSE (S&P CNX Nifty)
- June 2001: Index options introduced
- July 2001: Stock options launched
- November 2001: Stock futures introduced
- Role of SEBI: Regulates and oversees the entire derivatives market in India
1.4 Product Types
| Product | Nature | Key Feature |
|---|---|---|
| Forwards | OTC (Over-the-Counter) | Customised, bilateral contracts between two parties |
| Futures | Exchange-Traded | Standardised contracts with daily settlement (MTM) |
| Options | Exchange-Traded | Right (not obligation) to buy/sell; buyer pays a premium |
| Swaps | OTC | Exchange of cash flows (e.g., interest rate swaps) |
1.5 Market Participants
- Hedgers: They use derivatives to reduce risk. For example, a farmer sells wheat futures to lock in a price before harvest. They already own or plan to own the underlying asset.
- Speculators (Traders): They deliberately take on risk to make profits. They predict whether prices will go up or down and use leverage to amplify returns.
- Arbitrageurs: They exploit price differences between markets. For example, if Nifty futures are priced higher than the fair value, they sell futures and buy the underlying stocks to pocket a risk-free profit.
1.6 Trading Venues
| Feature | Exchange-Traded | OTC (Over-the-Counter) |
|---|---|---|
| Standardisation | Fully standardised (lot size, expiry, etc.) | Customised to parties' needs |
| Counterparty Risk | Eliminated by clearing corporation | Exists — depends on the other party |
| Transparency | High (prices visible to all) | Low (private negotiations) |
| Regulation | SEBI-regulated | Less regulated |
| Example | Nifty Futures on NSE | Forward contract between two companies |
📈 2. Understanding the Index
A stock market index is like a thermometer for the market — it tells you how the overall market (or a segment of it) is performing by tracking a basket of selected stocks.
2.1 Significance of Indices
- Benchmark: Indices serve as a reference point. If your portfolio grew 12% but Nifty grew 15%, you actually underperformed the market.
- Indicator: They reflect overall market sentiment — whether investors are bullish or bearish.
- Underlying for Derivatives: Index futures and options (like Nifty Futures) are among the most traded derivatives in India.
2.2 Weighting Methods
| Method | How It Works | Example |
|---|---|---|
| Market Capitalisation | Stocks with higher market cap get more weight | Most common globally |
| Free-Float | Only publicly tradable shares considered (excludes promoter holdings) | Nifty 50, Sensex |
| Price-Weighted | Stocks with higher prices get more influence | Dow Jones Industrial Average |
| Equal-Weighted | Every stock gets same weight regardless of size | Nifty 50 Equal Weight Index |
2.3 Impact Cost & Liquidity
Impact Cost measures how much extra you pay (or less you receive) when executing a large order. It is the percentage degradation from the ideal price. Lower impact cost = more liquid market. SEBI uses impact cost as a criterion for including stocks in the derivatives segment.
2.4 Major Indian Indices
- Sensex (BSE): 30 stocks, free-float market cap weighted — India’s oldest index
- Nifty 50 (NSE): 50 stocks, free-float market cap weighted — most widely tracked index
- Nifty Bank: Banking sector index — very popular for F&O trading
- SX40 (NSE): A newer broad market index
2.5 Applications of Indices
- Index Funds: Mutual funds that replicate the index composition — passive investing at low cost
- ETFs (Exchange-Traded Funds): Trade like stocks but track an index — combine stock flexibility with index diversification
- Index Derivatives: Futures and options on indices (e.g., Nifty Futures, Bank Nifty Options) — used for hedging, speculation, and arbitrage
📊 3. Forwards & Futures
Both forwards and futures are agreements to buy or sell an asset at a predetermined price on a future date. The key difference is that forwards are private and customised, while futures are standardised and exchange-traded.
3.1 Forward Contracts
- Bilateral: Agreement directly between two parties (no exchange involvement)
- Customised: The quantity, quality, delivery date, and price are all negotiated
- Counterparty Risk: Since there is no clearing house, if one party defaults, the other suffers a loss
3.2 Futures Features
| Feature | Detail |
|---|---|
| Standardisation | Lot size, expiry date, tick size are fixed by the exchange |
| Exchange-Traded | Traded on NSE/BSE through electronic order matching |
| Margining | Both buyer and seller deposit margin money as collateral |
| Daily Settlement (MTM) | Profits/losses settled every day based on closing price |
| No Counterparty Risk | Clearing corporation acts as counterparty to both sides |
3.3 Key Terminology
- Basis: The difference between the spot price and the futures price. At expiry, basis converges to zero.
- Cost of Carry: The cost of holding the asset until delivery = Interest cost − Dividends earned. This is what makes futures typically trade at a premium to spot.
- Open Interest: Total number of outstanding (unsettled) contracts. It shows market depth and participant interest.
- Traded Volume: Number of contracts traded during a specific period (like a day).
3.4 Pricing Models
Cost of Carry Model: Futures Price = Spot Price × e(r−d)×T
Where r = risk-free rate, d = dividend yield, T = time to expiry.
Expectations Model: The futures price reflects the market’s expectation of what the spot price will be at expiry.
Where r = risk-free rate, d = dividend yield, T = time to expiry.
Expectations Model: The futures price reflects the market’s expectation of what the spot price will be at expiry.
3.5 Payoff Profiles
- Long Futures (Buyer): Profit when price goes UP. Loss when price goes DOWN. The payoff is linear — unlimited profit and unlimited loss potential.
- Short Futures (Seller): Profit when price goes DOWN. Loss when price goes UP. Also linear payoff but in the opposite direction.
💡 4. Introduction to Options
An option gives you the right, but not the obligation, to buy or sell an asset at a specific price on or before a certain date. You pay a premium upfront for this right — think of it like buying insurance.
4.1 Types of Options
| Type | Right | When Profitable | Max Loss (Buyer) |
|---|---|---|---|
| Call Option | Right to BUY | When market price rises above strike price | Premium paid |
| Put Option | Right to SELL | When market price falls below strike price | Premium paid |
Remember: Option buyers have limited loss (only the premium paid) but unlimited profit potential. Option sellers collect the premium but face potentially unlimited loss. This is why options have asymmetric payoffs.
4.2 Moneyness
| Status | Call Option | Put Option | Meaning |
|---|---|---|---|
| In-the-Money (ITM) | Spot > Strike | Spot < Strike | Has intrinsic value — exercising would give profit |
| At-the-Money (ATM) | Spot = Strike | Spot = Strike | No intrinsic value — exactly at breakeven |
| Out-of-the-Money (OTM) | Spot < Strike | Spot > Strike | No intrinsic value — exercising would cause loss |
4.3 Pricing Factors (Black-Scholes Model)
- Spot Price: Current market price of the underlying. Higher spot = higher call premium, lower put premium.
- Strike Price: The price at which you can exercise. Lower strike = more valuable call, less valuable put.
- Volatility: How much the price fluctuates. Higher volatility = higher premiums for both calls and puts.
- Time to Expiry: More time = more premium (more chance of favorable movement).
- Interest Rate: Higher rates increase call premiums and decrease put premiums slightly.
4.4 Option Greeks
The “Greeks” are mathematical measures that tell you how sensitive an option’s price is to various factors:
| Greek | What It Measures | Simple Explanation |
|---|---|---|
| Delta (Δ) | Sensitivity to underlying price change | If Delta = 0.6, the option price moves ₹0.60 for every ₹1 move in the stock |
| Gamma (Γ) | Rate of change of Delta | How fast Delta itself changes — important for ATM options |
| Theta (Θ) | Time decay | How much premium you lose each day just due to time passing |
| Vega (v) | Sensitivity to volatility | How much the premium changes for 1% change in implied volatility |
| Rho (ρ) | Sensitivity to interest rate | Change in premium for 1% change in risk-free interest rate |
4.5 Intrinsic Value vs. Time Value
Option Premium = Intrinsic Value + Time Value
Intrinsic Value: The real, tangible value if you exercised right now. Only ITM options have intrinsic value.
Time Value: The extra amount you pay for the possibility that the option might become more profitable before expiry. Time value decreases as expiry approaches (this is Theta decay).
Intrinsic Value: The real, tangible value if you exercised right now. Only ITM options have intrinsic value.
Time Value: The extra amount you pay for the possibility that the option might become more profitable before expiry. Time value decreases as expiry approaches (this is Theta decay).
🎯 5. Trading Strategies
Strategies combine multiple positions in futures and options to achieve specific risk-reward goals. Here are the major categories:
5.1 Vertical Spreads
| Strategy | Construction | Market View | Risk/Reward |
|---|---|---|---|
| Bull Call Spread | Buy lower strike call + Sell higher strike call | Moderately Bullish | Limited profit & limited loss |
| Bear Put Spread | Buy higher strike put + Sell lower strike put | Moderately Bearish | Limited profit & limited loss |
| Bull Put Spread | Sell higher strike put + Buy lower strike put | Moderately Bullish | Limited profit & limited loss |
| Bear Call Spread | Sell lower strike call + Buy higher strike call | Moderately Bearish | Limited profit & limited loss |
5.2 Volatility Strategies
- Long Straddle: Buy a Call + Buy a Put at the same strike and expiry. You profit when the price makes a big move in either direction. Use this when you expect high volatility but are unsure of direction.
- Long Strangle: Buy an OTM Call + Buy an OTM Put at different strikes. Cheaper than a straddle but needs an even bigger move to be profitable.
- Short Straddle: Sell a Call + Sell a Put at the same strike. You profit when the price stays near the strike (low volatility). But risk is unlimited if the market moves sharply.
- Short Strangle: Sell an OTM Call + Sell an OTM Put. Similar to short straddle but with a wider profit zone and lower premium collected.
5.3 Income/Protection Strategies
- Covered Call: You own the stock + Sell a call option on it. You earn extra income (the premium) but cap your upside. Best when you expect the stock to stay flat or rise slightly.
- Protective Put: You own the stock + Buy a put option on it. This is like buying insurance — if the stock falls, the put protects you. Your downside is limited to (stock price − strike price + premium paid).
- Collar: Own stock + Buy a put (downside protection) + Sell a call (to fund the put). Limits both your upside and downside.
5.4 Arbitrage
- Cash and Carry Arbitrage: When futures are overpriced compared to fair value, you buy the stock in the spot market and sell the futures. You lock in a risk-free profit.
- Reverse Cash and Carry: When futures are underpriced, you sell the stock short and buy futures. Profits from the price convergence.
- Put-Call Parity: A fundamental relationship: Call − Put = Spot − PV(Strike). If this equality breaks, arbitrage opportunity exists.
⚙️ 6. Trading Mechanism
This section covers how trading actually works on the exchange — who the participants are, what types of orders you can place, and how technology is used.
6.1 Entities in the Trading Ecosystem
| Entity | Role |
|---|---|
| Trading Member (TM) | Brokers registered with the exchange who execute trades on behalf of clients |
| Clearing Member (CM) | Responsible for settling trades and managing margins. Must have higher net worth. |
| Client | The end investor or trader who places orders through a trading member |
6.2 Order Types
- Market Order: Buy or sell immediately at the best available price
- Limit Order: Buy or sell only at a specific price or better
- Stop-Loss Order: Triggered when the price reaches a specified level — protects against big losses
- Day Order: Valid only for the current trading day; cancelled if not executed
- IOC (Immediate or Cancel): Must be filled immediately or the unfilled portion is cancelled
6.3 Algorithmic Trading
- Co-location: Placing servers physically close to the exchange’s servers for ultra-low latency (millisecond advantage)
- APIs: Application Programming Interfaces allow automated order placement and management
- Risk Controls: SEBI mandates circuit filters, order-level checks, and kill switches to prevent algo-trading mishaps
6.4 Corporate Action Adjustments
When a company announces a corporate action, the exchange adjusts derivative contracts accordingly:
- Bonus Issue: Strike price and lot size are adjusted proportionally
- Stock Split: Similar to bonus — lot size increases, strike price decreases
- Dividends: Special dividends may trigger adjustments; regular dividends usually do not
💲 7. Clearing & Settlement
After a trade is executed, it goes through clearing (determining who owes what) and settlement (actual transfer of money/securities). The clearing corporation ensures everyone pays up!
7.1 Clearing Process
- Novation: The clearing corporation becomes the buyer to every seller and the seller to every buyer. This eliminates counterparty risk completely.
- Interoperability: Allows clearing across different exchanges (NSE trades can be cleared through BSE’s clearing corp and vice versa)
7.2 Settlement Types
| Type | When | How |
|---|---|---|
| Daily MTM | Every trading day | Profit/loss based on closing price; settled in cash by T+1 |
| Final Settlement | On expiry day | Based on closing price of underlying on expiry day |
7.3 Physical vs. Cash Settlement
- Cash Settlement: Only the price difference is exchanged in cash. Used for index derivatives (you cannot “deliver” an index).
- Physical Settlement: Actual shares are delivered/received. SEBI has mandated physical settlement for stock derivatives in India.
7.4 Margining System
| Margin Type | Purpose | Description |
|---|---|---|
| SPAN Margin | Initial Margin | Calculated using Standard Portfolio Analysis of Risk — considers various market scenarios |
| Initial Margin | Upfront deposit | The sum of SPAN margin + Exposure margin, deposited before trading |
| Exposure Margin | Additional safety | Extra margin beyond SPAN to cover extreme situations |
| Peak Margin | Intraday check | SEBI checks margins at 4 random snapshots during the day — you must maintain margin at all times |
⚖️ 8. Regulatory & Legal Framework
The Indian derivatives market is governed by a robust legal framework to protect investors and ensure market integrity.
8.1 Key Legal Acts
| Act | Year | Key Relevance |
|---|---|---|
| Securities Contract (Regulation) Act (SCRA) | 1956 | Derivatives are classified as “securities” under this Act, giving SEBI the authority to regulate them |
| SEBI Act | 1992 | Established SEBI as the supreme regulator for the securities market including derivatives |
| Prevention of Money Laundering Act (PMLA) | 2002 | Anti-money laundering provisions applicable to all financial market participants |
8.2 Compliance Requirements
- KYC (Know Your Customer): Every client must complete KYC before trading. This includes PAN card, Aadhaar, address proof, and income declaration.
- Anti-Money Laundering (AML): Brokers must report suspicious transactions and maintain records as per PMLA guidelines.
- Net Worth Requirements: Trading members and clearing members must maintain minimum net worth as specified by SEBI.
8.3 Investor Protection
- SCORES (SEBI Complaints Redress System): Online platform where investors can file complaints against listed companies and intermediaries
- ODR Portal: Online Dispute Resolution platform for faster resolution of securities market disputes
- IGRS/IRRA Platform: Investor Grievance Redressal System for handling investor complaints systematically
Exam Tip: For the NISM exam, make sure you know the roles of SEBI, the exchange, the clearing corporation, and the depository. Also understand the difference between SCRA and SEBI Act — SCRA deals with contract regulation, SEBI Act deals with market regulation.

❓ Self-Assessment Quiz
Click “Show Answer” to reveal each answer. Test yourself before peeking!
Q1: What is a derivative, and what are the primary categories of underlying assets?
A derivative is a contract whose value is derived from an underlying asset, such as metals, energy resources, agricultural commodities, or financial assets like shares, bonds, and indices. It serves as a tool for risk transfer and price discovery.
Q2: How do the roles of hedgers and speculators differ?
Hedgers use derivatives to reduce or eliminate existing price risk associated with an asset they own or plan to own. Speculators deliberately take on risk by predicting future price movements to achieve profits, often using leverage provided by derivative instruments.
Q3: Explain the concept of “Impact Cost” and its relationship to market liquidity.
Impact cost is the percentage degradation from the ideal price (average of best bid and ask) experienced when executing a trade of a specific size. It is a practical measure of liquidity — a lower impact cost indicates a more liquid market.
Q4: What is the difference between a Price-Weighted Index and an Equal-Weighted Index?
A Price-Weighted Index gives stocks with higher prices more influence over the index performance (like Dow Jones). An Equal-Weighted Index assigns the same weight to every constituent stock, requiring frequent rebalancing as prices fluctuate.
Q5: Distinguish between “Open Interest” and “Traded Volume.”
Open Interest represents the total number of outstanding contracts that have not been settled or closed, indicating market depth. Traded Volume reflects the total number of contracts that changed hands during a specific period like a single trading day.
Q6: What is “Cost of Carry” in equity derivatives?
Cost of carry is the relationship between futures and spot prices, calculated as the interest paid to finance the asset purchase minus any dividends earned during the holding period. It represents the net cost of carrying the position until the delivery date.
Q7: Define “Marking to Market” (MTM) and explain its purpose.
MTM is the daily settlement process where profits and losses are calculated based on the closing price of the futures contract. The exchange collects losses from certain participants and pays them to gainers daily to mitigate the risk of default.
Q8: What does it mean for a call option to be ITM versus OTM?
A call option is In-the-Money (ITM) when the spot price is higher than the strike price, giving it intrinsic value. It is Out-of-the-Money (OTM) when the spot price is lower than the strike price, meaning no intrinsic value exists.
Q9: What are “Option Greeks”, and what does “Theta” measure?
Option Greeks are mathematical measures of an option’s sensitivity to various factors like price, time, and volatility. Theta specifically measures “time decay” — the rate at which an option’s premium decreases as it approaches its expiration date.
Q10: When would a trader use a Long Straddle strategy?
A Long Straddle involves buying both a call and a put option with the same strike price and expiry. It is used when a trader expects significant price volatility but is uncertain about the direction of the movement.
