内容摘要：We propose a novel sentiment measure for China’s stock market. It captures investors’enthusiasm for IPO stocks revealed by both IPO prices and volumes. Loadings on the sentiment measure or IPO betas negatively predict the cross-section of stock returns. The return difference between low and high IPO beta stocks is not explained by known stock market anomalies and risk factors. The IPO beta anomaly is more pronounced for stocks with higher information ambiguity, larger capital lose overhang, and more short interest. Our results indicate that the anomaly reflects mainly mispricing and limits to arbitrage.
