S&P 500 History Shows Strongest Returns in Year After Midterms

Historical S&P 500 returns identify the calendar year after U.S. midterm elections as the strongest part of the presidential cycle, giving 2027 a favorable historical context without establishing a market forecast.

An analysis of 19 presidential cycles from 1950 through 2025 found average S&P 500 price returns of 8.4% in the first year of the cycle, 4.6% in the midterm year, 17.2% in the following year and 8.1% in the presidential-election year. The figures exclude dividends.

The 17.2% result measures the calendar year after a midterm election. It should not be treated as a forecast for 2027 or as a standalone investment signal.

The S&P 500 tracks 500 leading U.S. companies and represents about 80% of available U.S. market capitalization. Its historical performance after midterms offers context for 2027, but the election calendar alone does not determine returns.

Corporate earnings, economic growth, monetary policy, inflation and valuations could outweigh the election-cycle effect. Higher Treasury yields can raise corporate borrowing costs and make bonds more attractive relative to stocks, while persistent inflation could restrict the Federal Reserve’s ability to cut interest rates.

Technology earnings and artificial intelligence investment may also influence the index. Concerns about high valuations or weak returns on AI spending could weigh on performance.

Election results may change expectations for corporate taxes, tariffs, government spending and regulation. The market’s reaction would depend partly on how much anticipated policy change is already reflected in asset prices.
