We utilize the model of Llorente, Michaely, Saar and Wang (2002) to exam the dynamic volume-return relation of individual stocks in Taiwan stock market. In the LMSW (2002) model, investors trade to share risk and speculate on private information, and the show that hedging trades generate negatively autocorrelation returns, whereas speculative trades generate positively autocorrelation returns. We use daily volume and return data of stocks listed on TSEC to test the prediction of the model. Our results, which are consistent with LMSW (2002), show the cross-sectional variation in the relation between volume and return autocorrelation is related to the degree of information asymmetry. When we use some difference proxies of information asymmetry to test, the dynamic volume-return relation in Taiwan still consists with the theoretical prediction of LMSW (2002).
