Profitability of return and volume-based investm

Author(s): Changyun Wanga, Shengtyng Chin

Abstract: We examine the informational role of the interaction between past returns and past trading volume in the prediction of cross-sectional returns over intermediate horizons in China’s stock market. Our results show that low-volume stocks outperform high-volume stocks, volume discounts are more pronounced for past winners than for past losers, low-volume stocks experience return continuations, and high-volume winners exhibit return reversals. Our results are robust to risk adjustments relative to Fama and French’s three-factor model, and to stock exchange as well as large stock sub-samples. Our findings are not entirely consistent with the literature, which are likely to result from the market characteristics, in particular, the short-sales prohibition and the dominance of individual investors in the market.
