Price Discovery and Volatility Spillover between Spot and Futures Markets : Evidence from India

The present study investigates the role of information in price discovery function and volatility spillover in Nifty and S&P CNX Nifty futures by employing two-step TGARCH procedures. First, the study examines short and long-run relationship between S&P CNX Nifty index and Nifty index futures in near month, next month and far month prices by employing Engle-Granger cointegration and error correction model. The results of cointegration test show that there is long-run equilibrium relationship between spot and futures markets, and the spot market tends to make adjustments to re-establish the equilibrium during the next period. The results of TGARCH model reveal a bidirectional volatility spillover between spot and near, middle and far month futures
