一月效应

一月效应是从统计学角度分析股市走势的一种惯常现象,指1月份的回报率往往是「正数」,而且会比其他月份为高;相反在12月的股市回报率很多时会呈现负值。在传统股市智能之中,每逢踏入新一年的1月,股市总是升的多,跌的少。最初出现一月效应的国家是美国,然后其他国家的学者也陆续发现一月效应存在其他股市之中。

对于一月效应的出现,学者认为这与美国「资本增值税」的税务安排、基金粉饰厨窗、员工的年终花红及美国年尾的重要假期(感恩节、圣诞节、元旦)有莫大关系。

January effect 一月效应

The January effect is a hypothesis that there is a seasonal anomaly in the financial market where securities' prices increase in the month of January more than in any other month. This calendar effect would create an opportunity for investors to buy stocks for lower prices before January and sell them after their value increases. As with all calendar effects, if true, it would suggest that the market is not efficient, as market efficiency would suggest that this effect should disappear.
