摘要

反向投资和动量投资是股市中最强劲、最令人费解的资产定价异常现象。本文研究了股权分置改革后中国股票市场的赢家和输家投资组合的表现。结果表明,只有在亏损投资组合中才存在反向效应;而动量效应只存在于赢家投资组合中。

On the existence of inertial and reversal effects in China stock market of the post share structure reform
Contrarian and Momentum are the strongest and most puzzling asset-pricing anomalies in stock market. We investigates the performance of winner and loser portfolio in China stock market after the share structure reform in this paper. The results reveal that there is the contrarian effect only in loser portfolio; while the momentum effect is observed only in winner portfolio.
