Post-Election April and May

  • SumoMe

The best seven month period for the stock market historically extends from the end of October to the end of May.  As we head into the “home stretch” of this period it is also interesting to note that the April/May period during post-election years has tended to be favorable in recent decades.

Murphy’s Law being what it is, none of this should be taken as a sign that the MidCap Index is sure to rise between the end of March and the end of May in 2017 (especially given that it lost roughly -0.6% on the 1st trading day of April).  Still, I history proves to be an accurate guide investors may be wise to “ignore the news” and “ride the trend”.
