Pre-Election Year Seasonal Patterns

22 December 2006: Today's chart illustrates how the stock market has performed during the average pre-election year. Since 1900, the stock market has tended to outperform during the first six to seven months of the average pre-election year. For the remainder of the year, pre-election performance has tended to be choppy and slightly subpar. In the end, however, the stock market has tended to outperform during the entirety of the pre-election year. One theory to support this behavior is that the party in power will make difficult economic decisions in the early years of a presidential cycle and then do everything within its power to stimulate the economy during the latter years in order to increase the odds of re-election.
