June's Curse: Why Stocks Often Stumble in a Midterm Year

Every June, a familiar warning resurfaces on Wall Street. In a midterm election year, the history behind it gets harder to ignore.

The Seasonal Slump

June has a reputation problem. Historically, it ranks as one of the weakest months of the year for U.S. stocks, and in midterm election years it has been the single worst month on the calendar. That doesn't mean stocks always fall in June, but the pattern shows up often enough that traders keep one eye on the calendar.

What the History Shows

After a strong run, markets often drift into a period of short-term consolidation, where prices pause or pull back rather than push to new highs. Many investors expect exactly that this summer, treating June as a stretch to manage risk rather than chase gains.

Why Midterm Years Are Different

Election years bring an extra layer of uncertainty. With control of Congress up for grabs, investors face questions about taxes, spending, and regulation that won't be answered until November. Markets tend to dislike that kind of open-ended uncertainty, and the second and third quarters of a midterm year have historically been bumpy before a typical year-end recovery.

This June's Extra Headwinds

This year, seasonality isn't acting alone. Bets that the Federal Reserve could raise rates, an oil shock tied to the conflict with Iran, and a sharp sell-off in AI-related stocks have all landed at once. Layered on top of June's usual softness, those forces give the seasonal story more bite than usual.

'Sell in May' and Its Cousins

June's reputation is part of a broader bundle of Wall Street folklore, including the old saying "sell in May and go away." These patterns describe real historical tendencies, but they are averages across many decades, not predictions. Plenty of Junes have finished higher, and acting on seasonality alone has burned investors before.

The Bottom Line

Seasonality is a tendency, not a rule. June's track record is worth knowing, especially in a midterm year stacked with other risks, but it says nothing certain about what the next few weeks will bring. Long-term investors generally zoom out past any single month.
