As we approach another pivotal presidential election, the focus on economic indicators intensifies. One fascinating correlation that has emerged over the years is the relationship between stock market performance and election outcomes. A particular area of interest is the S&P 500 Index returns in the three months leading up to the presidential election. This metric has often been cited as a predictor of who will win the White House.
Historically, the performance of the S&P 500 Index in the months leading up to Election Day has shown a remarkable ability to predict the election’s outcome. The general observation is that when the S&P 500 posts gains in the three months before the election, the incumbent party is more likely to retain the presidency. Conversely, a declining market tends to favor the challenger party.
This intriguing pattern has held true for 20 out of the last 23 presidential elections, boasting an impressive accuracy rate of about 87%. The chart illustrates this trend, presenting a comprehensive view of the S&P 500 returns from 1928 through the 2020 election, alongside the election outcomes and whether the incumbent party won or lost.
