With many schools out for the week, the week of President's Day is often one where a more-than-average number of traders take the day off. While it may be a quieter-than-average week in terms of volume, though, market returns during the week are also weaker than average. The table below summarizes the returns of the S&P 500 since 1990 during the week of President's Day. In the 23 years since 1990, the S&P 500 has only seen positive returns during the week 10 times (43.5%) for an overall average decline of 0.50%.
