It further complicated the volatility behavior of these markets as derivatives opened new avenues for hedging and speculation. Since futures trading encourage speculation, the debate on the impact of speculators on the cash market volatility intensified with the introduction of futures trading. This constitutes the main research problem of this study and the objectives have been set out in accordance to this phenomenon of the derivatives market. The current research work examines the effect of the introduction of futures trading on the volatility of the underlying cash market in India.
