Statistical Models for Pricing Efficiency in Indian Derivatives Markets

This paper examines the pricing efficiency of index and stock options traded on the National Stock Exchange of India using a comprehensive framework of statistical tests. We analyze deviations from theoretical pricing models, investigate the term structure of implied volatility, and evaluate the predictive power of options-derived metrics for underlying asset returns. Our findings reveal systematic pricing patterns that differ significantly from mature derivatives markets.
