Stock Market Performance During Election Years
Every four years, the same question, “It’s an election year, what will the stock market do?”
Studies on Election Years and Market Returns
The table at the bottom of the page shows the return of the S&P 500 Index for each election year since 1928. At a glance, you can see that of the last 21 election years there have been only 3 years where the S&P 500 index had a negative return during an election year.
Marshall D. Nickles, EdD, expanded upon this data in a paper called . His detailed research shows that a profitable strategy would be to invest on October 1st of the second year of a presidential term and sell on December 31st of year four. After laying out the data to support this strategy, he goes on to say:
“However, just when you think that you have figured it all out, you find another pattern that can suggest different possibilities. For instance, another analysis shows a highly intriguing re-occurrence in the stock market index. During the entire twentieth century, every mid-decade year that ended in a “5” (1905, 1915, 1925, etc.) was profitable!”
The point he is making is the same point that a field of study called behavioral finance has told us over and over again; we may see patterns, but that doesn’t mean they are relevant to the decisions we are about to make.
In a study similar to Marshall’s, Wells Fargo’s Chief Investment Officer, Dean A. Junkans, CFA, and their Senior Investment Manager, James P. Estes, PhD, CFP(1) show that the average market return in the fourth year of a presidential term is twice that of the return in the first year of a president’s term.
Is this data useful? Only if the pattern continues.
If you're looking for a pattern, why not try the Super Bowl Stock Market Predictor. It says that "If the team that wins the Super Bowl has its roots in the original National Football League, the market will increase. If the winning team was originally from the old American Football League, the market will decline."
Making Decisions Based on Election Year Market Cycles
Suppose you hired an investment advisor who was familiar with the studies above. They show you the outstanding returns you would have experienced over the past twenty years if you had entered the stock market during the later years of presidential terms and exited during the initial years.
Likely, this advisor’s strategy would sound reasonable. You may even have had the expectation that in 2008, the market should have twice the return that it had in 2005. (In 2005 the S&P 500 Index returned 4.90%.) During the 2008 election cycle, if you invested on October 1 of 2006, until December 31st of 2008, your investments would have been down by 6.8%.
The pattern did not work for the 2008 election cycle. It looks like 2016 turned out well though! Oct 1, 2015, through year-end 2016 turned out to deliver a strong positive return.
What's in store for 2020? Your guess is as good as mine.
The problem with investing based on such data patterns: it’s not a sound way to go about making investment decisions. It sounds exciting, and it fulfills this deep-seated belief that many people have that there is a way to “beat the market’, and someone out there knows how to do it.
If that's not you, it might be better to invest the boring, safe way, which involves understanding risk and return, diversifying, and buying low-cost index funds to own for the long-term, no matter who wins the election. Or as a favorite quote on investing says, “Investing should be like watching paint dry or watching grass grow. If you want excitement…go to Las Vegas.” -Paul Samuelson
