文摘We examine the dynamic relation between returns,volume,and volatility of our futures markets.The results show that there exists a positive correlation between absolute returns and volume,but no correlation between returns and volume; Granger causality demonstrate that no causality relation exists between returns (or absolute returns) and volume,except copper’s absolute returns causes volume;the conditional volatility of returns has no direct impact to futures returns; copper’ and soybean’ trading volume contributes strong explanatory power to volatility,but aluminous’ trading volume has no direct impact to volatility.
