Welcome to the Historically Best Six Months of the Year

As the old trading axiom goes, selling in May and waiting six months to buy is a time-proven strategy. The good news about that is the November-to-April time frame is the strongest six months historically for equities. According to Ryan Detrick, Senior Market Strategist, “The strongest six months of the year are upon us. After a historically tight range the past three months, coupled with an improving earnings outlook and strengthening economy, it could be seasonality that helps the S&P 500 break out to the upside of its range.”

As this chart shows, going back to 1950,* the November-to-April time frame is indeed the best of all six month combinations (up 7.4% on average), while the May-to-October period is the worst, (up only 1.4% on average). In other words, nearly all of the gains tend to happen during the next six months.


What about the November-to-April time frame based on the Presidential Cycle? Going back to 1950, during the first year of the presidential cycle (November of an election year to April following the inauguration) those six months have averaged +3.4% and been higher 75% of the time. Looking at recent history though, these six months were down 9.9% from November 2008 to April 2009 and down 12.6% from November 2000 to April 2001. In other words, more recent Presidential cycles haven’t been too kind. Of course, both of those times were recessions and the economy is on fairly firm footing currently – one big difference as we head into 2017.


Lastly, what does it mean (if anything) when stocks climb higher during the historically weak May-to-October period during an election year? Remember, the S&P 500 has actually gained 2.9% over the last six months. Turns out, a gain between May and October in an election year (like we just saw in 2016) is a very good sign. Going back to 1980, the following six month period (November to April) has been higher seven out of seven times with an average return of +8.2%.
