An anatomy of calendar effects
This article studies the interaction and profitability of the five most well-established calendar effects: the Halloween effect, January effect, turn-of-the-month (TOM) effect, weekend effect and holiday effect. We find that Halloween and TOM are the strongest and most profitable effects. The equity premium over the sample 1963-2008 is 7.2 per cent if there is a Halloween or TOM effect, and 2.8 per cent in all other cases. An investment strategy based on these two effects gives higher net risk-adjusted returns than a passive buy-and-hold strategy. These findings are robust across different sample periods, market segments and international stock markets.
