Investing During a Presidential Election Year

Key Takeaways

Americans evaluate candidates for U.S. president, Congress and other public offices every four years. And given the rhetoric of today’s polarized political environment, you might worry about your portfolio or be reluctant to stick to your long-term investment strategy.

Are you considering cashing in to avoid potential market volatility during this presidential election year?

Historical stock and bond market data indicates giving in to this temptation wouldn't be wise. It’s important to remember that the long-term trend in stock and bond prices is positive. And, as we’ll point out in this article, this trend generally holds during presidential election years.

As shown in Panel A of Figure 1, U.S. stocks have historically surged as election-year campaigns reached their crescendos. Indeed, stocks have gained an average of 10% in presidential election years since 1976. On the downside, this stretch includes one of the worst years in U.S. stock history, a 37% drop amid the global financial crisis in 2008. The only other negative presidential election year result since 1976 was a 9% decline when the dot-com bubble burst in 2000.

On the other hand, the U.S. bond market (as measured by the Bloomberg U.S. Aggregate Bond Index) has never failed to deliver a positive presidential election year result over the last 50 years. See Panel B of Figure 1. On average, bonds have gained more than 7% when voters chose the commander in chief.

Pondering 2024 Stock Market Possibilities

Certain factors in the 2024 election may bode well for U.S. markets this year if history provides any guide.

President Joe Biden seeks reelection, and the S&P 500^® Index hasn’t declined during any election year that an incumbent sought another term since Dwight Eisenhower did so in 1956. In the 10 reelection campaigns since then, the index has risen an average of more than 18%.¹

Moreover, the 2024 presidential race follows the 2022 mid-term election year when U.S. stocks declined. Since World War II, U.S. stocks have advanced during every year that a presidential election followed a stock market slide two years earlier. See Figure 2. The average gain is 13.4%.

Navigating Stock Market Volatility in U.S. Presidential Election Years

Regardless of their importance, presidential elections still take a back seat to economic conditions and national or global disasters. U.S. stocks have fallen in presidential election years only four times over the last 100 years. In these instances, historic events overshadowed each election’s impact:

• 1932, the stock market crash in 1929 and resulting Great Depression.

• 1940, the waning of the Great Depression and first full year of World War II.

• 2000, the dot-com bubble crash.

• 2008, the global financial crisis.

Investors head into this presidential election year coming off a 2023 in which a much-anticipated recession didn’t materialize. Recession concerns haven’t dissipated completely, but economic consensus suggests the Federal Reserve (Fed) will successfully negotiate a soft landing for the U.S. economy in 2024.²

Recession or not, investor uncertainty tends to heighten stock market volatility during the run-up to Election Day and then decreases afterward.³ We don’t think the possibility of higher volatility should cause investors to avoid the market. On the contrary, we believe investors should stick with their diversified investment strategy instead of trying to time the election by toggling between stocks and cash.

Stocks and Bonds Have Tended to Rise Regardless of the Election Cycle

Historical election-year market trends don’t affect how American Century’s portfolio managers select securities or make asset allocation decisions.

Moreover, it’s essential to recognize the limitations of the historical trends we’ve discussed. From a statistical standpoint, you shouldn’t rely too heavily on any trends or correlations the data may show.

However, the long-term performance of stocks and bonds remains impressive. The long-term stock market gains have historically overshadowed the short-term fluctuations influenced by external events like presidential elections.

Our analysis confirms that stocks and bonds have usually moved higher during presidential election years. And that’s primarily because they have tended to move higher in any given year – election or not. That’s why we think sticking to your diversified investment approach may be your most prudent vote.
