Presidential Elections and the Stock Market

Written by Tim Decker.

In a few days, Americans will head to the polls to elect the next president of the United States. In a recent article last month, I emphasized the importance of not allowing the upcoming presidential election to impact your personal financial plan and how you invest. Well, Election Day is now only days away. And while the outcome is unknown, one thing is for certain: There will be a steady stream of opinions from pundits and prognosticators about how the election will impact the stock market. As I emphasize and explain again below, investors would be well‑served to avoid the temptation to make significant changes to a long‑term investment plan based upon these sorts of predictions.

SHORT-TERM TRADING AND PRESIDENTIAL ELECTION RESULTS

Trying to outguess the market is often a losing game. Current market prices offer an up-to-the-minute snapshot of the aggregate expectations of market participants. This includes expectations about the outcome and impact of elections. While unanticipated future events—surprises relative to those expectations—may trigger price changes in the future, the nature of these surprises cannot be known by investors today. As a result, it is difficult, if not impossible, to systematically benefit from trying to identify mispriced securities. This suggests it is unlikely that investors can gain an edge by attempting to predict what will happen to the stock market after a presidential election.

Exhibit 1 shows the frequency of monthly returns (expressed in 1% increments) for the S&P 500 Index from January 1926 to June 2016. Each horizontal dash represents one month, and each vertical bar shows the cumulative number of months for which returns were within a given 1% range (e.g., the tallest bar shows all months where returns were between 1% and 2%). The blue and red horizontal lines represent months during which a presidential election was held. Red corresponds with a resulting win for the Republican Party and blue with a win for the Democratic Party. This graphic illustrates that election month returns were well within the typical range of returns, regardless of which party won the election.

LONG-TERM INVESTING: BULLS & BEARS ≠ DONKEYS & ELEPHANTS

Predictions about presidential elections and the stock market often focus on which party or candidate will be "better for the market" over the long run. Exhibit 2 shows the growth of one dollar invested in the S&P 500 Index over nine decades and 15 presidencies (from Coolidge to Obama). This data does not suggest an obvious pattern of long-term stock market performance based upon which party holds the Oval Office. The key takeaway here is that over the long run, the market has provided substantial returns regardless of who controlled the executive branch.

CONCLUSION

Equity markets can help investors grow their assets, but investing is a long-term endeavor. Trying to make investment decisions based upon the outcome of presidential elections is unlikely to result in reliable excess returns for investors. At best, any positive outcome based on such a strategy will likely be the result of random luck. At worst, it can lead to costly mistakes. Accordingly, there is a strong case for investors to rely on patience and portfolio structure, rather than trying to outguess the market, in order to pursue investment returns.

This again is why I continue to encourage you to remain committed to your personal, goal-driven financial plan, and to remember that markets have historically rewarded those of us who remain disciplined and are prudently invested.
