Think the big market move comes before the votes are counted? History says wait for the sequel. The midterm election stock market history going back to 1874 says the real action comes after Election Day, not before. A new Motley Fool analysis of Robert Shiller’s data found the S&P 500 rose in the 12 months following 32 of 38 midterms. That is 84% of the time, with an average gain of 14%.
The next test arrives Tuesday, Nov. 3. So what does the long record actually say about the weeks around it?
Midterm Election Stock Market History: The Before and After
The run-up has been decent, if unspectacular. The Fool’s numbers show the S&P 500 averaged about 4% in the six months before a midterm, and it was positive 63% of the time. In the final month before Election Day, the average was 1.5%, with a gain 76% of the time, according to the Stacker syndication of the report.
The first month after the vote is where it gets awkward. Stocks averaged just 0.5% and rose only 55% of the time, which is barely better than a coin flip. The bigger gains showed up later: roughly 6% at three months and 10% at six months.
In other words, patience has been the trade. That’s not a typo.
Is an 84% Record Actually Special?
Before you get too excited: stocks go up most of the time anyway. The same study shows the average 12-month period since 1871 returns 11% and is positive 73% of the time. A post-midterm year beats that, but not by a mile.
The size of the political beating also doesn’t seem to matter. The Fool found no close link between how many House seats the president’s party loses and what stocks do next. Midterms with losses of 40 seats or more averaged returns similar to the tamer ones, per the Tucson.com copy of the report. Wall Street, it turns out, doesn’t much care who wins the shouting match.
Fidelity makes a similar point. Its research says markets respond more to shifts in policy uncertainty than to which party wins, and that earnings and the economy drive long-term returns. Fidelity’s midterms and stocks guide is worth a read if you want the cautious version. Washington’s finances matter too: the $2 trillion federal deficit is one more reason rates deserve a close watch.
Why the Stock Market After Midterms Looks Different Depending on the Source
If you’ve seen a different percentage elsewhere, you’re not imagining it. Start the clock in 1950 and the S&P 500 has been higher 12 months after all 19 midterms, averaging roughly 15%, per another Fool piece. Fidelity counts price gains since 1938 and lands at 95%.
Different start years, price versus total return, calendar years versus post-election windows. Each choice moves the answer (statistics, meet the buffet line). This analysis also traces back to a single source, so treat the exact figures as a guide rather than gospel.
One more catch: the calendar midterm year itself has historically been weaker. Edward Jones puts the average since 1970 at about 3.6%, and the S&P 500 fell in both 2018 and 2022.
This Year Is Already Off Script
2026 has not followed the usual midterm-year script. BlackRock says U.S. stocks were up 13.1% through August, the sixth-best start to a midterm year since 1926, in its midterm market review. The March dip was about 9%, well short of the 19% average midterm-year drawdown.
On Friday, the S&P 500 closed at 7,811.54, up 0.59%, and finished the week about 1.2% higher. That sits just under its record close of 7,818.93 from Oct. 6.
The backdrop isn’t calm, though. Longer-dated Treasury yields hit new 24-year highs this week, and oil is elevated. Iran tensions and an AI-trade stumble have also rattled traders, CNBC reported. Individual stocks are feeling it as well, as Nike’s removal from the S&P 100 shows.
What Midterm Election Stock Market History Means for Investors
Here’s the thing: about 150 million Americans own stocks, according to the Fool, so this isn’t a Wall Street parlor game. It’s your 401(k). The midterm election stock market history is encouraging, but it describes the past, not a promise. Nobody has ever banked a profit on a pattern alone.
The smarter read is the boring one: ignore the noise around the vote, and watch earnings, inflation and rates. The history says the first month after Nov. 3 may be the shakiest stretch, and the data suggests the payoff, if there is one, comes later.
So will 2026 extend the streak or finally break it? Ask again next year.
