股票市场月收益率的多维分析

Multidimensional Analysis of Monthly Stock Market Returns

Osman Gulseven

摘要:

本研究考察了土耳其和美国股票市场指数的月度回报率,以调查这些市场在日历年的某些月份是否经历了异常回报。本研究使用的数据包括1996年1月至2014年8月期间的212次观测。我应用统计汇总分析,分解技术,虚拟变量估计和二元逻辑回归来检查月度市场异常。本文中使用的多维方法表明,对月收益率有效市场假说的证据不足。虽然有些月份往往会出现异常收益,但所应用的方法并没有绝对的一致性。尽管如此,在4月份出现正回报后,5月份对土耳其股市的影响明显负面。两个市场的股票在12月都趋于看涨,但我们没有观察到1月的显著影响。

英文摘要:

This study examines the monthly returns in Turkish and American stock market indices to investigate whether these markets experience abnormal returns during some months of the calendar year. The data used in this research includes 212 observations between January 1996 and August 2014. I apply statistical summary analysis, decomposition technique, dummy variable estimation, and binary logistic regression to check for the monthly market anomalies. The multidimensional methods used in this article suggest weak evidence against the efficient market hypothesis on monthly returns. While some months tend to show abnormal returns, there is no absolute unanimity in the applied approaches. Nevertheless, there is a strikingly negative May effect on the Turkish stocks following a positive return in April. Stocks tend to be bullish in December in both markets, yet we do not observe anya significant January effect is not observed.
