Every year around now, like clockwork, an old Wall Street saying makes the rounds: sell in May and go away.
The pitch sounds almost reasonable. Stocks supposedly do their best work from November through April, so the logic goes that you cash out for the summer, skip the sleepy, choppy months, and stroll back in come autumn. Sell in spring, sip something cold all summer, return rested and richer.
It's catchy. It rhymes. And as an actual strategy for your money, it's shakier than it sounds. Let's walk through what's really going on and then talk about the summer money moves that matter a lot more.
Where the saying even comes from
The phrase has roots in old British high society, back when the well-off would leave London for the countryside over the warmer months. The full version was something like "sell in May and go away, come back on St. Leger's Day," nodding to a horse race in September.
Over the years it got dressed up as a market theory. And there is some historical pattern behind it: looking back over many decades, the May-to-October stretch has, on average, delivered weaker stock returns than November-to-April. That part isn't made up.
The trouble is the leap from "weaker on average" to "you should sell."
Why acting on it usually backfires
A few problems hide inside that tidy little rhyme.
First, "weaker returns" is not the same as "negative returns." Summers are, on average, still positive more often than not. Sitting in cash for half the year to dodge a slightly-below-average stretch means you're frequently giving up real gains for an imaginary problem.
Second, the market refuses to read the calendar. Some of the strongest rallies in recent memory landed in summer months, and some of the ugliest drops showed up in supposedly "safe" winter ones. The averages smooth over a wild amount of year-to-year chaos.
Third — and this is the one that quietly does the most damage — getting out is only half the trade. You also have to get back in at the right moment, and that's where almost everyone trips. Markets do a frustrating amount of their heavy lifting in just a handful of days. Miss a few of the best ones because you were "waiting for a better entry," and your long-term return takes a real hit. Decades of data point the same direction: time in the market tends to beat timing the market.
And if you're selling in a taxable account, you can hand a chunk of your gains to the IRS and rack up trading costs, all for the privilege of guessing.
So, the honest answer for most long-term investors: if your plan was sound in April, it's probably still sound in July. Going to cash on a seasonal hunch is usually a swap of a real plan for a superstition.
The summer money risk that's actually worth worrying about
Here's the irony. People stress about what the market might do over the summer, while the genuine threat to their finances is sitting much closer to home: summer spending.
The warm months are quietly expensive. Travel and flights. Wedding season — between the gift, the outfit, and maybe a flight and hotel, a single invite can run several hundred dollars, and some summers bring a stack of them. Kids home from school, which means camps, childcare, and the bottomless "I'm booored" budget. Higher electric bills as the AC runs nonstop. The casual patio dinners and weekend trips that feel small in the moment and look enormous on the August statement.
None of it is a crisis on its own. The danger is the drift — the slow creep where three relaxed months blow a hole in your savings and you don't notice until the credit card bill lands in September.
A loose summer-spending plan beats a strict budget you'll abandon by July. Pick a number for the fun stuff, maybe park it in a separate account, and let yourself actually enjoy it without the quiet background guilt. Protecting your savings rate through the summer will almost certainly do more for your net worth than any clever seasonal market trade.
What to do with cash right now
Speaking of savings, if you've got cash on the sidelines, summer 2026 is a genuinely interesting moment for it.
Rates are still decent but they're easing off. The Fed has held its benchmark steady through its meetings so far this year, with the target range sitting at 3.50%–3.75% and the next decision due in mid-June. The strong high-yield savings accounts are still paying around 4% APY — but those rates have been drifting lower through the year, and they tend to follow the Fed down.
A reasonable way to think about your cash, by job:
Money you might need within a year or so — emergency fund, a wedding you're attending, next year's property tax. Keep it safe and reachable. A high-yield savings account still makes sense here, and locking part of it into a CD can hold today's rate before it slips further.
Money you won't touch for years — this is long-term money, and parking it in cash usually means inflation slowly eats its purchasing power. Historically, that's the money that belongs invested and growing, matched to your goals and how much bumpiness you can tolerate.
The mistake we see in both directions: people invest cash they'll need next month, then panic when the market dips — or they hoard cash they won't touch for fifteen years, quietly losing ground to inflation the whole time. Matching the money to its timeline is most of the battle.
Make the season work for you instead
If you want a summer money move that actually pays off, skip the market-timing game and do the unglamorous stuff:
Automate your investing so contributions keep flowing whether the market's up, down, or sideways — that's dollar-cost averaging, and it quietly removes emotion from the equation. Use any summer slowdown as a calm window to glance at your overall mix and rebalance if it's drifted. And keep feeding your long-term accounts on schedule, summer slump chatter or not.
Boring? A little. But boring, repeated for years, is what builds real wealth. The flashy seasonal trades mostly build stories.
Not sure which bucket your money belongs in?
That's the honest hard part — knowing how much cash to keep liquid, what to lock in before rates fall further, and what should stay invested for the long haul. The right answer depends entirely on your timeline, your goals, and your tolerance for the inevitable bumps.
That's the conversation we have every day at Feller Financial Services.

Enjoy your summer. Just don't sell it to a rhyme.
