问题如下:
Following are some typical market anomalies, which of them contradicts the weak form of the efficient market hypothesis?
选项:
A.Closed-end fund discount.
B.Momentum pattern.
C.Earnings surprise.
解释:
B is correct.
The momentum pattern indicates that by using historical price information, analysts are able to earn abnormal returns, which is inconsistent with weak-form market efficiency.
考点:Tests, Implications And Conclusions Of EMH
弱势有效市场假定投资者不能根据市场过去交易的量、价信息获取超额收益。
但是MOMENTUM PATTERN却是认为过去的价格走势可以延续,并依据过去的价格信息获取超额收益,这是违反弱势有效市场假设的。
A和C都只是一种市场异象,原版书并没有提及他们试图推翻的是哪种市场有效情况,因此不在考纲要求范围之内,对该异象简单了解即可。
不是说Market Anomalies都不能推翻弱势有效或者半强有效吗
