What Are Stock Derivatives?

Stock derivatives are financial instruments whose value is derived from an underlying stock or basket of stocks. Unlike direct stock ownership, derivatives allow traders to gain exposure to price movements without owning the underlying asset. The two primary categories are futures and options.

Core Characteristics

  • Leverage: Control large positions with relatively small capital (margin)
  • Expiration: All derivatives have a finite lifespan
  • Settlement: Can be cash-settled or physically delivered
  • Standardization: Exchange-traded contracts have fixed lot sizes, expirations

Why Trade Stock Derivatives?

Derivatives serve three main purposes: hedging existing positions, speculating on price direction, and arbitraging price discrepancies across markets.

Types of Stock Derivatives

Stock Futures

A futures contract obligates the buyer to purchase (or seller to sell) the underlying stock at a predetermined price on a specific future date. In India, single stock futures are available on NSE and BSE for select stocks meeting SEBI eligibility criteria.

Stock Options

Options give the buyer the right, but not the obligation, to buy (call) or sell (put) the underlying at a strike price before expiry. Key types:

  • Call Options: Right to buy at strike price
  • Put Options: Right to sell at strike price
  • European vs American: Exercise only at expiry vs any time before expiry

Index Derivatives

Derivatives on stock indices like Nifty 50, Bank Nifty, Sensex, and global indices (S&P 500, FTSE 100, DAX). These are among the most liquid derivative contracts globally.

Contract Type Underlying Liquidity Primary Use
Stock Futures Individual Stocks Moderate Hedging, Speculation
Stock Options Individual Stocks Low-Moderate Income, Hedging, Leverage
Index Futures Stock Indices High Portfolio Hedging, Directional Bets
Index Options Stock Indices Very High Complex Strategies, Income

How Stock Derivatives Work

Margin System

Exchanges use a SPAN (Standard Portfolio Analysis of Risk) margin system. Initial margin covers potential losses, while maintenance margin triggers margin calls. For example, a Nifty futures contract (lot size 50) at 22,000 requires ~10-15% margin (~110,000-165,000 INR).

Mark-to-Market (MTM)

Daily settlement of profits/losses based on closing prices. MTM gains are credited, losses debited from margin account.

Expiry and Settlement

  • Monthly Expiry: Last Thursday of each month (India)
  • Weekly Expiry: Every Thursday for index options
  • Physical Settlement: Mandatory for stock derivatives (SEBI mandate)
  • Cash Settlement: For index derivatives

Futures vs Options: Key Differences

Feature Futures Options
Obligation Both parties obligated Buyer has right, seller obligated
Risk Profile Unlimited for both Limited for buyer (premium), unlimited for seller
Upfront Cost Margin (10-20%) Premium (2-5% of notional)
Payoff Linear Non-linear (asymmetric)
Greeks Not applicable Delta, Gamma, Theta, Vega, Rho

Frequently Asked Questions

What is the minimum capital required to trade stock derivatives in India?

Minimum capital depends on the contract. For Nifty futures (lot size 50), at 22,000 level with 12% margin, you need ~132,000 INR per lot. For stock futures, margins range from 10-25% of contract value. Options buyers only need premium (typically 2-5% of notional).

How are stock derivatives taxed in India?

F&O trading income is treated as business income under “Profits and Gains from Business or Profession” and taxed at applicable slab rates. STT at 0.01% (futures sell) and 0.05% (options premium) applies. Losses can be carried forward for 8 years against future business income.

What is physical settlement in stock derivatives?

Physical settlement means on expiry, the seller delivers actual shares to the buyer at the strike/futures price, instead of cash difference. SEBI mandated physical settlement for all stock derivatives from 2019 to reduce speculation and improve market integrity.

Can retail investors trade global derivatives from India?

Yes, through GIFT City IFSC exchanges (NSE IFSC, India INX) offering USD-denominated derivatives, or via international brokers under LRS ($250,000/year limit). Popular products include CME micro E-minis and Eurex index derivatives.

What are the key differences between NSE and BSE derivatives?

NSE has ~99% market share in derivatives, higher liquidity, tighter spreads, and more eligible stocks. BSE derivatives have lower volumes but offer some unique index products. Most traders prefer NSE for execution quality.

How do option Greeks affect trading decisions?

Delta measures directional sensitivity, Gamma measures delta change, Theta measures time decay, Vega measures volatility sensitivity, Rho measures interest rate sensitivity. Traders use Greeks to hedge, size positions, and select strategies matching their market view.

What is the difference between European and American options?

European options can only be exercised at expiry, while American options can be exercised anytime before expiry. Indian index options are European; some stock options on global exchanges are American. Early exercise risk affects American option pricing.
