Do Mid-Term Elections Affect the Stock Market? What High-Net-Worth Investors Need To Know

Worried about how the mid-term elections will impact your investments?

Every two years, headlines begin predicting how a change in Washington could alter the direction of the economy and financial markets. Investors are bombarded with forecasts, political commentary, and warnings about what may happen if one party gains or loses power.

For affluent households, election cycles can create pressure to make changes at exactly the wrong time. Emotional decisions during periods of political debate can interrupt years of disciplined investing and lead to costly mistakes.

Historical evidence tells a different story. While elections can create temporary market swings, the primary drivers of stock returns have remained remarkably consistent across decades. Understanding that distinction can help you stay focused on what truly matters.

Do Mid-Term Elections Impact the Stock Market?

Historically, not much. While markets have strong seasonal tendencies, especially in mid-term election years and may experience elevated short-term volatility leading up to a mid-term election, longer-term returns have generally been driven by corporate earnings, economic growth, inflation, and Federal Reserve policy rather than political control in Washington.

The Pre-Election Volatility Dip

Markets dislike uncertainty. Investors often speculate about taxes, regulations, and government spending ahead of a mid-term election, which can drive market swings. Data from 1928 through 2025 shows the S&P 500 declined an average of 2.76% between the end of April and September during mid-term election years, making it the weakest stretch of the four-year presidential cycle. What that data doesn’t show is a higher-than-average stock market correction during that period, especially for first-term presidents. 

The Post-Election Relief Rally

Once the election results are known, a major source of uncertainty is removed. Stocks have often performed better in the quarters following mid-term elections as investors shift their attention back to earnings, economic data, and interest-rate expectations.

The Gridlock Effect

A divided government is frequently viewed neutrally or even favorably by financial markets. When power is split between political parties, major legislative changes often become more difficult to pass. 

Historically, markets have generated positive returns under both unified and divided governments, suggesting economic and corporate fundamentals tend to matter more than political control over extended periods.

Why Your Portfolio Depends on More Than Election Results

Political events attract attention because they are highly visible. The Federal Reserve, interest rates, and corporate earnings reports often receive far less public discussion despite having a greater influence on market returns.

Corporate Earnings Matter More Than Campaigns

Over extended periods, stock prices generally reflect the value of the underlying businesses. Revenue growth, profit margins, cash flow, innovation, and competitive position influence company valuations far more than election slogans or campaign promises. Investors who focus solely on political developments often overlook the factors that actually drive returns and get stuck on narratives.

Economic Conditions Drive Market Direction

Interest rates affect borrowing costs, consumer spending, housing activity, and corporate investment. Inflation influences purchasing power and profit margins. Global trade, labor markets, technological innovation, and capital flows also shape investment outcomes.

These forces continue operating regardless of election results.

The Cost of Reacting to Headlines

Election years can tempt investors to make emotional decisions. Weak investors follow their emotions. The problem is that political forecasts rarely provide a reliable basis for investment decisions. Markets respond to a wide range of factors, which is why using geopolitics in investing is a losing strategy.

At Heritage Capital, we utilize a variety of active, top-down strategies rather than making sweeping portfolio changes based solely on an upcoming election. Our mission is to provide clients with strong returns throughout the full market cycle. Our clients benefit from both strategic and asset diversification.

Tailor Your Strategy: Retirement Planning for High-Net-Worth Individuals

As wealth grows, investment decisions become much more complicated. The focus extends beyond accumulating assets. Taxes, income distribution, estate plan considerations, charitable objectives, and portfolio construction all become increasingly intertwined.

Election headlines rarely have as much impact on retirement outcomes as these factors.

Tax-Loss Harvesting

Temporary market declines can create opportunities to offset capital gains through tax-loss harvesting. This technique allows investors to realize losses strategically while maintaining appropriate market participation.

Asset Location

Different investments generate different forms of taxable income. Holding tax-inefficient assets in retirement accounts while allocating more tax-efficient holdings to taxable accounts can improve after-tax returns over multiple years.

Income Buckets

Many retirees benefit from maintaining designated reserves for near-term spending needs. When living expenses are covered by cash reserves and income-producing assets, you’re less likely to sell equities during market declines.

Families focused on retirement planning in Connecticut also face state-level tax issues that deserve attention. State income taxes, estate planning considerations, and retirement income decisions often have a greater impact on household finances than a single election cycle.

Signs It’s Time to Audit Your Current Advisory Relationship

Election years sometimes reveal weaknesses in an advisory relationship.

Is Your Advisor Following the Headlines?

If an advisor recommends major portfolio changes based primarily on election predictions, switching financial advisors is an absolute. Nobody consistently predicts election outcomes or market reactions with reliable accuracy. Decisions driven by forecasts rather than evidence can increase risk rather than reduce it.

Volatility Can Expose Gaps

Periods of uncertainty often highlight communication problems. Some discover they’re not receiving the level of guidance, education, or responsiveness they expected. Others realize their advisor has not clearly explained portfolio positioning or tax implications.

Making a Change Doesn’t Have To Be Difficult

If you’re considering changing financial advisors, the transition process is usually far simpler than you might think. Most account transfers occur through ACATS, the Automated Customer Account Transfer Service. Assets can often move electronically without requiring you to liquidate holdings first.

Our team can conduct a thorough review of tax implications, unrealized gains, and portfolio composition before any changes are implemented.

The Fiduciary Distinction: The Value of a Fee-Only Partner

Not all advisors operate under the same compensation model. Some advisors receive commissions from financial products they recommend. Others operate as fiduciaries and charge advisory fees directly to clients.

For example, a fee-only financial advisor in New Haven, CT, reduces certain conflicts because compensation is not tied to product sales or trading activity.

At Heritage Capital, transparency is central to every client relationship. We are a fee-only fiduciary firm. We charge advisory fees and do not receive commissions for recommending investment products.

Our fees are straightforward. Clients pay a single fee based on assets under management. Fees are deducted quarterly in arrears rather than in advance. Before any engagement begins, fee information is provided in writing so you understand exactly what you’re paying and what services are included.

Temporary political cycles come and go. Sound investment decisions are built around factors that have affected markets for decades.

Has the stock market historically performed well after mid-term elections?

While every election cycle is different, historical market data has shown a strong tendency toward positive performance in the year following many mid-term elections.

Why does the Federal Reserve matter more than elections?

Interest rates influence borrowing costs, consumer spending, business investment, and corporate profitability. These factors generally have a larger effect on market returns than political outcomes.

What should I look for when evaluating a new financial advisor?

Consider the compensation structure, fiduciary obligations, communication style, investment philosophy, tax knowledge, and experience working with individuals in financial situations similar to yours.
