Why Staying the Course Matters
Election years can make investors uneasy. Headlines grow louder, political rhetoric intensifies, and market volatility often follows. For many investors, midterm elections can feel like turning points that may reshape the economy, alter tax policy, or change investment outcomes.
Yet history tells a calmer story.
While political uncertainty can affect market sentiment in the short term, long-term investment performance has historically depended more on economic fundamentals, corporate earnings, innovation, and disciplined investing than on which political party controls Washington. For investors, the key lesson is not to react emotionally to election cycles, but to stay focused on long-term financial goals.
A Capital Group analysis of more than 90 years of market history highlights several important trends investors should understand about midterm election years.
Midterm Elections Often Create Anxiety, but Markets Adapt
Midterm elections occur halfway through a presidential term and are often viewed as a referendum on the sitting administration. Historically, the president’s party tends to lose seats in Congress, which can shift the balance of legislative power.
Historical data shows that the president’s party has lost an average of 27 House seats and three Senate seats during midterm elections over the past several decades. Investors often view these elections as periods of uncertainty because changes in congressional control can affect policy priorities, spending, taxes, and regulation.
Still, financial markets are forward-looking. Much of the anticipated political change is often reflected in market prices before Election Day. By the time ballots are cast, investors and institutions have usually adjusted their expectations.
That helps explain why election-related market fears often prove temporary rather than lasting.
Markets Tend to Slow During Midterm Years
Stock market returns during midterm election years have typically been more subdued than average.
Since 1931, the S&P 500 has generated average returns of about 4.7% during midterm years, compared with roughly 9.5% during non-midterm years.
The reason is straightforward: markets dislike uncertainty. Early in an election year, investors often face unanswered questions about legislation, fiscal policy, taxes, and regulatory priorities. As uncertainty rises, investors may become more cautious, which can slow market momentum.
Even so, this pattern should be kept in perspective. Markets have historically remained positive overall during many midterm years, although market declines can still occur. Investors who leave the market during uncertain periods risk missing later rebounds.
That is an important reminder: trying to time the market around political events is difficult and often counterproductive.
Election Years Often Bring Higher Volatility
For investors watching daily market swings, election cycles can feel stressful. Historical data supports that view.
Midterm election years have generally experienced higher market volatility than other years. Political campaigns can heighten concerns about inflation, taxes, health care, trade, government spending, and corporate regulation. These narratives can trigger emotional reactions and short-term market turbulence.
Volatility has often risen most sharply in the months leading up to Election Day. But short-term volatility is a normal part of investing. It should not automatically be viewed as a sign of long-term market weakness.
In some cases, volatility can create opportunities for disciplined long-term investors who remain diversified and focused on their financial plans.
Markets Have Historically Rebounded After Midterms
One of the more encouraging historical patterns is what has happened after midterm elections.
Historically, markets have often recovered once political uncertainty begins to fade, although past trends do not guarantee future results Since 1950, the average one-year market return following midterm elections has been about 15.4%, nearly double the average return during other periods.
This reinforces an important principle: uncertainty often weighs more heavily on markets than the election outcome itself.
Once investors gain more clarity about the political and economic landscape, confidence tends to improve. Businesses continue operating, consumers continue spending, and markets refocus on earnings growth, interest rates, and broader economic conditions.
Of course, every election cycle is different. Inflation trends, Federal Reserve policy, geopolitical tensions, global growth, and corporate profits all continue to play major roles in market performance. Elections are only one factor among many that influence investor sentiment.
Political Control Has Had Limited Long-Term Impact
One of the more notable findings from long-term market history is that investment returns have remained relatively strong under different political arrangements.
Since 1933, markets have delivered double-digit average annual returns across unified governments, divided governments, and split congressional control.
That highlights a point many investors overlook: markets are often more resilient than political headlines suggest.
Companies continue to innovate. Businesses adapt. Economies evolve. While policy changes can affect specific industries or sectors, long-term wealth creation has historically been driven by productivity, earnings growth, technological advancement, and consumer demand.
What Investors Should Focus On Instead
Rather than reacting emotionally to election headlines, investors may benefit from focusing on enduring financial principles.
They should maintain a diversified portfolio aligned with long-term goals. They should avoid making major investment decisions based solely on politics. They should stay disciplined during periods of volatility, review their financial plans regularly, and focus on time in the market rather than timing the market.
Political uncertainty may dominate headlines for months, but history suggests that patient, long-term investors are often rewarded for staying invested through the noise.
As financial professionals, one of the most valuable roles we can play is helping clients separate short-term emotion from long-term strategy. Elections come and go. Markets fluctuate. But disciplined investing, thoughtful planning, and perspective remain among the most reliable drivers of long-term financial progress.
