Stock market performance after a midterm election.
Since 1950, the U.S. stock market has exhibited an exceptionally strong and consistent track record in the months following midterm elections. In fact, the 12-month period following a midterm election has historically been one of the strongest stretches of the four-year presidential election cycle.
The quarter of the election and the next two quarters are historically the strongest nine months of the election cycle for stocks. Small stock indexes often outperform the S & P this was not the case in the 2022 cycle as small stocks trailed the S & P by 10%.
Across all 19 midterm election cycles from 1950 through 2022, the S&P 500 has posted positive returns 12 months later in 100% of cases:
Market Index
| Time Horizon Post-Election | Average S&P 500 Gain | Win Rate (% Positive) |
| 1 Month | ~1.6% | ~79% |
| 3 Months | ~7.7% | ~89.5% |
| 6 Months | ~14.1% | 100% |
| 12 Months | ~15.1% – 15.2% | 100% (19 for 19) |
- Median 12-month gain: ~14.5%
- Best 1-year performance: +33.2% (following the 1954 midterms)
- Worst 1-year performance: +1.1% (following the 1986 midterms, which absorbed the October 1987 “Black Monday” crash)
Primary Drivers Behind the Post-Midterm Trend
- Resolution of Policy Uncertainty: Markets generally dislike ambiguity. The months leading up to a midterm vote often bring elevated volatility as investors price in potential changes to tax codes, regulation, and trade policy. Once ballots are counted, certainty returns—regardless of which party wins.
- Divided Government & Legislative Gridlock: Midterms frequently result in the president’s party losing seats, leading to a split Congress or divided government. Wall Street often views legislative gridlock favorably because it diminishes the likelihood of sweeping, disruptive tax hikes or major regulatory overhauls.
- The Presidential Cycle Effect: Year three of a presidential term historically tends to be the strongest calendar year for equities, as administrations focus on economic stability and market-friendly measures ahead of the next presidential campaign.
Key Caveats for Investors
- Midterm Years vs. Post-Midterm Years: While the 12-month stretch after midterms has a spotless track record, the calendar year leading up to Election Day is often choppy and prone to pullbacks (notably cycles like 2018 and 2022).
- Fundamentals Rule Over Politics: While the historical pattern is compelling, long-term market performance remains dictated by corporate earnings, Federal Reserve interest-rate policy, inflation & broader macroeconomic conditions rather than election outcomes alone.
