Market Performance Ahead of Midterm Elections
- The S&P 500 historically performs well post-election, averaging 0.2% gains after one week.
- Divided government tends to favor market performance, with an average 15% increase post-elections.
- Factors such as AI trends and Federal Reserve policies could greatly influence market stability.
Markets are bracing for the impact of the upcoming midterm elections, but historical data suggests that such elections often lead to strong stock performance, irrespective of the political outcomes. The S&P 500 index has shown resilience, rising an average of 0.2% one day and one week following election events, and 1.1% after one month based on a CNBC analysis covering elections from 1980 to 2024. Over the long term, the average gain is even more pronounced, with the index increasing by 13.7% after midterms and 13.8% after presidential elections.
Specifically, the S&P 500 rose following each of the 11 midterm elections between 1982 and 2022. In contrast, short-term returns post-presidential elections have been less consistent, often reflecting a slight downturn in the days immediately following the polls.
Ryan Detrick, CNBC contributor and chief market strategist at Carson Group, noted that while there is pre-election anxiety, once the elections conclude, markets tend to stabilize and improve.
Market Preference for Divided Government
Financial markets generally favor divided government, where one party controls the White House and the other holds at least one house of Congress. In analysis of 10 midterm and five presidential elections featuring divided government, the S&P 500 recorded an average increase of 15% within a year, with positive returns in 14 of 15 instances. In comparison, elections resulting in single-party control showed only an 11.5% annual growth.
Detrick emphasized that extreme political shifts, like significant red or blue waves, may disrupt market stability due to potential, excessive government spending. The analysis also highlighted that scenarios where Democrats control Congress while a Republican is in the White House have historically been favorable for the S&P 500, which has averaged a 3.4% increase a month post-election in such cases.
However, it is essential to consider that elections are often coincidental to broader market influences. For instance, the S&P 500 plummeted by 22.1% in the year following the 2000 elections, primarily due to the dot-com bust, marking the worst post-election performance since 1980. Conversely, the index surged by 38.3% after the 2020 elections, driven by a rebound from a COVID-19-related downturn.
According to Société Générale, factors like Federal Reserve policies and corporate earnings cycles play a more critical role in market performance than election outcomes. After the 2018 midterms, when Democrats gained House control, the S&P 500 declined by 6.2% that year, attributed to tightening monetary policies by the Fed.
Currently, the evolving landscape surrounding AI advancements and the outlook for technology investments remains pivotal. Detrick suggests that as long as the momentum in AI continues alongside economic growth, the current bull market could persist. Conversely, a Democratic sweep could hinder AI infrastructure developments. Additionally, global bond market volatility, as seen with rising yields and the crisis in France, may further complicate investor sentiment, along with escalating tensions related to Iran.
Market dynamics are expected to remain influenced by geopolitical factors alongside monetary policy as investors anticipate potential stock rallies following the midterms.
