The Summer Doldrums, should Investors “Sell in May and Go Away”?
Every year, usually right around the time people start thinking about golf, graduation parties, and whether the grill still works, an old Wall Street phrase starts making the rounds:
“Sell in May and go away.”
The idea is simple: the stock market supposedly performs poorly during the summer months, so investors should sell in May, avoid the so-called “summer doldrums,” and come back later in the year.
Cute phrase. Not a great financial plan.
What Are the Summer Doldrums?
The “summer doldrums” refer to the idea that markets can feel slower during the summer. Trading volume may be lighter because investors, traders, and decision-makers are on vacation. News flow can quiet down. Markets may drift sideways. Some days feel like Wall Street put on flip-flops and forgot to come back from lunch.
But “quiet” does not always mean “bad.”
Markets can still rise during the summer. They can also fall. They can do absolutely nothing for weeks and then move sharply in three days. That is the problem with trying to build an investment strategy around a calendar slogan.
Why “Sell in May” Sounds Tempting
The phrase is tempting because it gives investors something we all secretly want: a shortcut.
It suggests there might be an easy seasonal pattern to follow. Sell here. Buy there. Avoid the pain. Capture the gains.
Unfortunately, investing is rarely that tidy.
It is a little like saying, “It usually rains more in April, so I’ll never schedule anything outdoors that month.” That may sound logical, but you would miss plenty of beautiful days. And sometimes the thunderstorm shows up in June anyway.
The stock market works the same way. Seasonal tendencies may exist, but they are not dependable enough to replace a long-term plan.
The Bigger Risk: Missing the Best Days
One of the biggest dangers of “Sell in May” is that market returns often come in unpredictable bursts.
You do not usually get a polite email from the stock market saying:
“Good morning. Just a heads up, three of the best trading days of the year will happen next week. Please be invested accordingly.”
The best days are often clustered near periods of uncertainty, volatility, and bad headlines. If you are sitting on the sidelines waiting for the “right” time to get back in, you may miss the recovery.
That is like leaving a hockey game halfway through the second period because your team is down two goals, then finding out they scored three times while you were in the parking lot.
Summer Can Be Noisy, But Noise Is Not a Strategy
Summer markets can be frustrating. One week investors are worried about inflation. The next week they are worried about the Fed. Then earnings. Then oil prices. Then politics. Then whether consumers are still spending. It can feel like the market is trying to ruin your vacation on purpose.
But short-term noise should not drive long-term decisions.
For most investors, the better question is not:
“Should I sell because it is May?”
The better question is:
“Does my portfolio still match my goals, risk tolerance, income needs, and time horizon?”
That question is useful in May, October, January, and every other month of the year.
What Investors Should Do Instead
Rather than selling just because the calendar changed, summer can be a good time for a portfolio checkup.
Review your cash needs.
Rebalance if your allocation has drifted.
Look at whether your bonds, stocks, and cash still fit your plan.
Consider tax opportunities if markets have created gains or losses.
Make sure your portfolio is built for more than one season.
A good investment plan should not need a beach chair and a margarita to survive the summer.
Final Thought
“Sell in May and go away” is memorable because it rhymes, not because it is reliable.
The market does not care what month it is. It cares about earnings, interest rates, inflation, valuations, investor expectations, and sometimes just plain old emotion.
Summer may bring slower trading and occasional market chop, but that does not mean investors should abandon their plan. More often, the best move is to stay disciplined, stay diversified, and use the quieter months to make sure the portfolio is still doing its job.
Because when it comes to investing, the goal is not to win May, June, or July.
The goal is to build wealth through many seasons.
