Trading Calendar – December
The following chart shows the average month-to-date percentage change in the S&P 500 index by trading day during December from 1990 through 2014. Day 0 represents the November close. The index during December tends to be positive, with the gains coming mostly at the beginning of the month and toward the end of the month (Santa Claus rally). We have not used data for trading day 22, because most Decembers do not have 22 trading days. Also, sample size is only 18-25 for specific trading days, so these results are only weakly suggestive rather than predictive. For 1990-2014, 20 Decembers have been winners and only five losers.
