Midterms Likely To Shake Up Your Stock Portfolio — The 95% Statistic Investors Should Know

“Macro policy and earnings/valuations, not the election outcome itself, will drive returns over the next 12 months.”

Midterms historically stir volatility but rarely derail longer trends; the article leans on long-run stats (S&P 500 up ~95% in 12 months after midterms; 1-year average ~15.4%) while skimming macro drivers. The missing context matters: inflation, Federal Reserve policy, earnings momentum, and valuations drive returns far more than which party sits in Congress. The strongest risk to the upbeat reading is that rates stay higher for longer and earnings growth undershoots, limiting multiple expansion even if Congress gridlocks. The post-election window may also be priced in, and sector impacts depend on actual policy details rather than the outcome alone.

“Historical midterm performance is a lagging indicator of liquidity cycles rather than a predictive model for current market returns under restrictive monetary policy.”

The article leans heavily on the '95% win rate' statistic to soothe investor anxiety, but it ignores the current macro regime shift. While historical midterms often rally due to the resolution of political uncertainty, we are currently operating under a restrictive monetary policy environment that is fundamentally different from the low-rate eras of the past 70 years. The '15.4% average return' cited by Capital Group is largely a function of liquidity cycles, not just election outcomes. If the Fed maintains 'higher for longer' rates, the historical correlation between midterms and market performance may decouple, as valuation multiples struggle to expand against persistent inflation and tightening credit conditions.

“The 95% statistic is real but meaningless without knowing what drove those gains, and current valuations + Fed policy matter far more than election outcomes for 2025 returns.”

The article leans heavily on a cherry-picked statistic: 95% of S&P 500 12-month windows post-midterm showed gains since 1938. But this ignores survivorship bias—we're measuring from 1938 onward, after the Depression bottom. More critically, the article conflates 'gains in the 12 months following' with 'midterms caused gains.' The real drivers—Fed policy, earnings, valuations—are mentioned as afterthoughts. We're in a 4.5% 10-year Treasury environment with 20x+ forward multiples on mega-cap tech. Midterm clarity might matter less than whether the Fed pivots in Q1 2025.

“The 95% post-midterm gain statistic is likely less predictive this cycle because starting valuations and monetary conditions differ sharply from the historical sample.”

The article cites Fidelity's 95% hit rate for S&P 500 gains in the 12 months after midterms since 1938 and Capital Group's 15.4% average return since 1950. Those figures ignore that most of those cycles began at far lower valuations and with less aggressive Fed tightening than today's environment. Current drivers—persistent inflation, Iran-related supply risks, and earnings revisions—were absent or milder in the bulk of the sample. Policy gridlock may reduce legislative surprises, yet it does nothing to alter the path of monetary policy or corporate margins that the piece itself concedes are the dominant variables.
