Index and Stock Option Dispersion Trading with Dynamic Delta Hedging

Summary

This project describes a dispersion strategy on Bank Nifty index options and constituent bank stock options. It takes relative volatility positions using combinations of straddles or strangles: when implied correlation is high, the example suggests selling index options and buying component options; when it is low, it suggests the reverse. Black–Scholes implied volatilities are used to estimate the relationship between index and weighted component volatility. Futures hedge directional exposure, with portfolio delta adjusted at regular intervals.

The workflow covers implied volatility and correlation estimation, option selection, ongoing hedging, exit and stop loss planning, and profit and loss from both options and futures. It identifies 15-minute data as the main example and mentions 30-minute data as an alternative, without presenting enough evidence to establish which performs better. The document supplies no detailed backtest results or quantified risk analysis, and its claims of attractive risk and reward are not substantiated. Results would depend on liquidity, transaction costs, model assumptions, and hedge frequency.

Key ideas

• Dispersion trading takes relative volatility exposure between an index and its components.
• The example uses implied volatility to form a view on index component correlation.
• Straddles and strangles provide the options exposure, while futures help control directional delta.
• The project adjusts delta regularly and includes stop loss and exit planning.
• The document does not supply quantified evidence supporting its broad profitability claims.
