Abstract:
This paper uses stock market returns (2007-2015) and confirms the existence of Halloween effect anomaly after the 2008 financial crisis. Findings suggest that the Halloween effect can still be observed in 34 out of the 35 countries. A more aggressive trading strategy of shorting the market during summer and taking a long position in winter yields 4.77% more than the buy-and-hold strategy. A new explanation is offered for the persistence of the Halloween effect. A positive feedback between investors belief and behavior causes the market to underperform in the summer and recover in the winter, resulting in a self-fulfilling prophecy.
