S&P 500 Midterm Election Streak: Will 2026 Break the Record?

### Session Tape - S&P 500: +0.73%

## Catalyst Analysis: Historical Midterm Seasonality vs. Current Tape Midterm election years traditionally introduce heightened volatility for domestic equities, yet historical data reveals an unblemished record for subsequent 12-month periods. Since the S&P 500 was established in its current 500-company format in 1950 across 19 midterm election cycles, the index has never posted a negative return twelve months after the vote. According to historical calculations cited from Robert W. Baird & Co., the S&P 500 has averaged a 32% gain over the one-year window following midterm elections, with historical positive prints occurring 95% of the time across the index and its predecessor.

Despite severe historical disruptions—including the Korean War and the 1973 oil shock—the 12-month post-midterm window has consistently delivered positive performance. Current market positioning reflects a 13% gain heading deeper into the cycle, setting up a closely watched test for whether macroeconomic and political dynamics in 2026 can interrupt the multi-decade historical tendency.

### Money Play - Macro and historical seasonality suggest maintaining discipline across broader index allocations as the 12-month post-midterm window approaches.
