股票收益率的三个"基本面'成分(风险合理补偿的预期收益、未来现金流与贴现率预期变化产生的现金流和贴现率信息)中,现金流信息最有可能出现短期反转.文章第一次使用修正的分析师预测测度现金流信息,构造基于残差收益率的短期反转策略研究中国股市的短期反转效应,实证结果发现该策略能产生相比标准反转策略更高的经过风险因子调整的回报率.进一步,基于分离出现金流信息的方法,从投资组合的多、空两方发现主要是流动性冲击而非投资者情绪能解释中国股票市场的短期反转现象.文章从残差收益率的新视角检测A股短期反转策略,不仅丰富了资产定价金融异象领域的研究,亦提供了以中国为例的新兴市场关于理解短期收益反转理论的国际化证据.
Short-Term Reversal Effect in the Chinese Stock Market:Evidence from Residual Returns
The"fundamentals"that determine expected stock returns consist of three components:The expected return component that is rationally compensated for systemic risk,the cash flow news generated by changing expectations of future cash flows,and the discount rate news generated by changing expectations of rational future discount rates.Of these,cash flow news that are not driven by fundamentals are the component most likely to reverse in the short term.In this paper,for the first time,we use analyst forecast revisions to measure cash flow news and construct a short-term reversal strategy based on residual returns to study the short-term rever-sal effect in the Chinese Stock Market.The empirical results find that the strategy generates higher risk-factor-adjusted returns compared to the standard reversal strat-egy.Further,the methodological test based on isolating cash flow news finds that liquidity shocks rather than investor sentiment can explain the short-term return re-versal phenomenon in the Chinese Stock Market from both the long and short leg of the portfolio.This paper examines the short-term reversal strategy of A-shares from a new perspective of residual returns,which not only enriches the research in the area of financial anomalies in asset pricing,but also provides international evidence on understanding the theory of short-term return reversal in emerging markets,with China as an example.
