In this study we examine the relationships between trader-type-specific trading volumes and the price volatility of the KOSPI200 stock index futures over the period of July 1997 through December 2001. The principal findings of this study are that the changes in trading volumes by foreign investors are positively associated with the return and the volatility of the index futures market. When trading volumes are decomposed into expected and unexpected components, unexpected shocks have more persistent effect on the volatility of the market than expected component. Meanwhile, individuals and domestic commercial investor seem to follow the lead made by foreign investors.

This paper examines the long- and short-run dynamic causality between the futures price and trading volume in the Malaysian equity market. The data of futures price, trading volume and spot price are in daily frequency, spanning from 2006 to 2009.

In addition, there exists a short-run bidirectional causality relationship running between futures return-trading volume and futures return-spot return. Thus, the stock index futures market in Malaysia is not informational efficient.
