Market Snapshot: Clearing the Midterm Overhang

The removal of midterm-election uncertainty and the prospect of divided government should create a more predictable policy environment that is supportive for equities.

• Democrats appear to have won majorities in both the House and Senate, likely shifting Congress toward oversight while leaving room for selective cooperation on healthcare, cost-of-living measures, and tax policy.
• The administration can still pursue trade, immigration, foreign policy, and deregulation largely through executive authority during the final two years of the president’s term.
• Since 1946, the S&P 500 has returned an average of 19.9% in the 12 months after midterm elections, versus 11.3% across all periods, with positive returns after all 20 midterms in the sample.
• Post-midterm volatility has been similar to the long-term average, with return standard deviation of 15.6% versus 15.8%, but average maximum drawdown was smaller at 11.6% versus 16.9%.
• Equity markets have historically benefited from divided control because bipartisan compromise limits sweeping changes to the rules affecting businesses and investors.

Takeaway: The historical record favors equities after midterms, but the small sample of 20 elections is not a guarantee; the more durable signal is that markets tend to reward reduced policy uncertainty rather than any particular party’s victory.
