The Only Months That Matter in 2017

  • SumoMe

2017 is a post-election year.  During the 1960’s to the 1980’s the “post-election year” gathered a reputation as being a “bad year” for the stock market.  But the truth is that starting in 1985 the post-election year has been a pretty good one for the stock market.

Figure 2 displays the growth of $1,000 during post-election years since from 1901 through 2016 broken down into two categories:

*The months of July and December only

*All other post-election year months

As you can see the months of July and December combined:

*Cumulative gain = +161%

*# times showing a net gain = 21 (72%)

*#times showing a net loss = 8 (28%)

The “Other” 10 months combined:

*Cumulative gain = +18%

*# times showing a net gain = 16 (55%)

*#times showing a net loss = 13 (45%)


So does this mean that we should have our money in a mattress until July? Not necessarily (obviously, with the Dow already up +5.4% for the year).  This tidbit of information regarding July and December of post-election years is not intended to constitute a “trading system” per se.

It is interesting to note though the relatively consistent performance for the stock market during these two months and the relatively inconsistent performance of the stock market during the other 10 months of the post-election year.
