The Empirical Investigation of Relationship between Return, Volume & Volatility in Indian Stock Market

This paper investigates the empirical relationship between return, volume and volatility dynamics of stock market by using data of the NIFTY index of NSE during the period from Jan 2007 to March 2014. The volatility in the Indian stock market exhibits characteristics similar to those found earlier in many of the major developed and emerging stock markets. It is shown that ARCH family models outperform the conventional OLS models. We find that, the TARCH model is better fit, when we compare the GARCH, EGARCH and TARCH models, on the basis of AIC and SC criteria. Causality from volatility to volume can be seen as some evidence that new information arrival might follow a sequential rather than a simultaneous process. Moreover, in the GARCH model, ARCH and GARCH effects remain significant, which highlights the inefficiency in the market. In addition, EGARCH and TARCH models indicate the presence of leverage effect and positive impact of volatility on returns. Finally, the findings of granger causality test records the evidence of one way causality from volatility to trading volume and from return to volume
