通过推广DSSW(1990)的噪音交易者模型,用投资者情绪理论解释了证券市场的“异象”,并对证券市场的部分“异象”进行了检验。研究发现,国内金融市场存在一个新的“异象”,即历史波动高的组合,其后收益率低,而历史波动低的组合,其后收益率高。并且发现,国内市场不存在价值溢价现象,尽管高PB的组合收益最低,但低PB的组合收益不是最高,而是中PB的组合收益最高,因此在国内运用FAMA三因子模型要谨慎。
'Anomalous' in stock market is explained by investors' sentiment with revised noise trader model (DSSW, 1990a) in this paper. Firstly, the authors find a new 'anomalous'--the much the volatility of portfolio has, the lower the return of portfolio is. Secondly, there is no value premium effect in the A stock market, therefore we should be cautious to apply Fama' s three factors model.
