Equity Futures and Trading

Summary of Equity Future Derivatives and Trading Strategies

Equity futures are financial contracts obliging the buyer to purchase, or the seller to sell, a specified quantity of an equity asset at a predetermined price on a future date. These derivatives serve as essential tools for hedging, speculation, and arbitrage in the Indian financial markets. Understanding the types of futures, margining mechanisms, key terminologies, pricing models, and trading strategies is crucial for market participants to manage risk and optimise returns effectively.

Types of Futures

• On the Basis of Maturity:

  • Short-Term Futures: Contracts with expiry typically within a few weeks to a few months.
  • Long-Term Futures: Contracts with expiry extending beyond a few months, sometimes up to a year.
  • Indian exchanges like NSE offer monthly expiry contracts, facilitating diverse investment horizons.

• On the Basis of Underlying Asset:

  • Single Stock Futures: Futures contracts based on individual stocks like Reliance Industries, TCS, etc.
  • Index Futures: Contracts based on stock indices such as Nifty 50 or Sensex, representing a basket of stocks.
  • These futures provide opportunities for sector-specific or broad market exposure.

Margining in the Futures Market

• Margining ensures the financial integrity of futures contracts by requiring participants to deposit a fraction of the contract value.
• Initial Margin: The upfront collateral deposited to enter into a futures position.
• Mark-to-Market (MTM) Margin: Daily adjustment of margin based on gains or losses due to price changes.
• Variation Margin: Additional margin calls made if the market moves against the trader.
• SEBI mandates margin requirements to reduce systemic risk and protect investors.

Terminologies Used in the Futures Market

• Contract Size: The quantity of the underlying asset covered by one futures contract.
• Expiry Date: The date on which the futures contract matures and settlement occurs.
• Open Interest: The total number of outstanding contracts that have not been settled.
• Settlement Price: The price used to mark contracts to market at the end of each trading day.
• Tick Size: The minimum price movement of the futures contract.

Futures Pricing – Cost of Carry Model

• The cost of carry model helps determine the theoretical futures price based on the spot price, interest rates, dividends, and storage costs.
• Formula:
  $F = S \times e^{(r - d) \times T}$
  where,
  $F$ = Futures price
  $S$ = Spot price of the underlying asset
  $r$ = Risk-free interest rate
  $d$ = Dividend yield of the underlying asset
  $T$ = Time to maturity (in years)
• This model assumes no arbitrage opportunities and helps traders identify mispriced futures contracts.

Trading Strategies Using Futures

• Hedging: Protecting an existing equity portfolio against adverse price movements by taking opposite futures positions.
• Speculation: Taking directional bets on the market to profit from price fluctuations without owning the underlying asset.
• Spread Trading: Simultaneously buying and selling futures contracts of different maturities or underlying assets to exploit price differentials.
• Arbitrage: Exploiting price inefficiencies between the spot and futures markets or between different futures contracts.
• Common in Indian markets where traders hedge exposure to volatile sectors like IT, Pharma, or Banking via futures.
