摘要
梳理了理论界对于市场异象的研究结论,针对市场异象的争议,提出了基于马尔可夫的市场异象持续性检验模型,利用1993~2010年我国A股市场的收益数据,对我国股票市场的价值溢价、规模溢价和动量溢价等市场异象进行实证检验。研究发现,我国A股市场的价值溢价与动量溢价在长期内存在持续性,规模溢价的持续性相对较弱,并且,生存偏差、收益平滑和统计区间对于市场异象的持续性存在不同程度的影响。
For the controversies among market anomalies,we put forward a persistence testing model based on Markov.Then an empirical study is undertaken to analysis the persistence of value premium,size premium and momentum premium on Chinese stock market during 1993 to 2010.We concluded that is that value premium and momentum premium exist continuously in A share market,while the continuity of size premium was poor,and,survivorship bias and return smoothing significantly influence the persistence of market anomalies.
