The benchmark S&P 500 index of the U.S. stock market has delivered double-digit returns for three consecutive years. Entering 2026—a typical midterm election year—while Wall Street expects the rally to continue, historical data reminds investors that the road ahead is often accompanied by significant turbulence.

Since its inception in 1957, the S&P 500 has exhibited a generally observable pattern during U.S. presidential midterm election years. In such years, the index has averaged an annual return of just 1%. If it coincides with a new president’s term, the average annual return further drops to -7%. Even more noteworthy is that historical data shows the index has suffered an average intra-year maximum drawdown as high as 18% during election years.

Midterm elections typically result in the ruling party losing seats in Congress, casting doubt on policy continuity. This uncertainty usually pressures the stock market. However, once the election results are finalized, policy uncertainty dissipates quickly, often triggering a strong market rally. Research indicates that the six-month period following a midterm election (November through April) is the strongest phase of the four-year cycle, during which the S&P 500 has historically gained an average of 14%.

Despite this historical pattern of volatility, Wall Street remains optimistic about 2026. According to the median analyst forecast compiled by FactSet Research, the S&P 500 has a target level of 8,085 points over the next 12 months, implying a potential upside of over 16% from its current level of around 6,940 points. However, Wall Street’s predictive accuracy has been inconsistent in recent years. Over the past three years, the median year-end target has deviated from the actual closing level by an average of 14 percentage points (for example, the 2024 forecast was 4,700 points, while the index actually closed at 5,882 points).

This year, the U.S. stock market may face additional volatility. The sustainability of a series of policies implemented by the Trump administration (such as tariffs) will depend on whether Democrats can win enough seats in Congress to amend or obstruct them. Expectations of potential policy reversals will likely continue to unsettle the market ahead of the election.

Facing a highly uncertain election-year environment, investors should consider the following strategies:

Avoid Market Timing, Focus on Long-Term Investing: Attempting to precisely predict market bottoms and time entries often backfires. Legendary fund manager Peter Lynch once warned that more money has been lost by investors preparing for corrections than in the corrections themselves.

Concentrate on High-Conviction Ideas: Focus investments on companies you thoroughly understand and firmly believe in for their long-term value, and only buy stocks you are willing to hold through market fluctuations.

Build Cash Reserves: Now is a good time to increase cash holdings within your portfolio. If the market enters a correction zone as the election approaches, history suggests such dips present good buying opportunities.

While elections have limited impact on the market’s medium-to-long-term overall trajectory, they can significantly affect specific sectors. In short, the U.S. stock market in 2026 will navigate the interplay between the “historical pattern of midterm election volatility” and “Wall Street’s bullish expectations.” While embracing potential upside opportunities, investors need to remain vigilant about the inherent high volatility of election years and manage challenges through prudent stock selection and asset allocation.
