[金融业] [2023-08-11]
作为东吴金工“行为金融拥抱选股因子”系列研究的第一篇,我们在2022年6月发布的《重拾自信选股因子——从过度自信到重拾自信》中,对行为金融学中一种常见的预期偏差——过度自信,进行讨论。我们根据经典的DHS模型,从“投资者过度自信的程度影响股价”的逻辑出发,用“股价快速上涨和快速下跌的时间差”作为代理变量,创新性地构造了过度自信CP因子。在此基础上,我们又做了进一步思考,考虑了既然投资者存在过度自信,那么股价回调时他们可能也会过度悲观,导致回调幅度过大,但是由于利好消息的存在,这种形态的股票之后一定会补涨。基于上述考虑,我们将第一代过度自信CP因子和日内收益正交,将残差项作为第二代重拾自信RCP因子。基于重拾自信RCP因子构造的组合,其表现明显优于传统组合方式。
