Trade volume and Return-volatility relationship on the Shenzhen stock market: an empirical analysis
This article examines the relationship between the trade volume and return-volatility of Shenzhen component index after the implementation of limit up or down. We got two conclusions. First,there only exists Granger Causality from return to trade volume,which verified that the commonly believed “trade volume makes price move is wrong. Second,the mixture of distribution hypothesis (MDH) is held on Shenzhen stock market. Different from the relative researches abroad,MDH is not held if the trade volumes are use as substitution variable of information that reached the market. However,both two parts have significant influence to the volatility of return when we divide the trade volume into expected and non-expected ones,which reduced the volatility persistence,and demonstrated that MDH is held on Shenzhen stock market.
