The present paper attempts to investigate whether the Previous day’s Nifty returns has an explanatory power for today’s Nifty returns. Daily data of sample of 3671 observations from January 2000 to December 2015 has been used for the study. CNX Nifty returns are calculated as the first difference of the log of the daily closing price. GARCH (1,1) has been developed to model the volatility of CNX Nifty returns. The GARCH model is a time series modeling technique which provides for Heteroscedasticity in the observed returns. Empirical results have shown that previous day’s Nifty returns have GARCH effect in the today’s Nifty returns.
