The stock market typically experiences a mixed reaction following a US presidential election, according to historical data. While stocks have historically risen in the weeks and months following Election Day, there can be short-term volatility. The three major benchmarks (S&P 500, Dow Jones, and Nasdaq) have averaged gains between Election Day and year-end since 1980, but have also seen declines in the session and week following voting days. Investors should be prepared for uncertainty as the outcome of the election may not be clear immediately.
