This year summer officially extends from June 21 to September 23, when the fall solstice arrives. There’s an old adage about warm weather doldrums on Wall Street that counsels, “Sell in May and go away!”

Per Investopedia, the phrase is based on an old English saying, “Sell in May and go away and come back on St. Leger’s Day.” During London’s hot summer months, merchants, bankers and aristocrats would decamp to the country and the shore, with a slump in trading and investment activity. St. Leger’s Day referred to the St. Leger’s Stakes, a major mid-September horse race, the last leg of the British Triple Crown, when all were back and business activity accelerated.

For years, Wall Street traders and bankers were said to abandon hot and stuffy New York City for the Hampton beaches of Long Island or the cooler Catskill Mountains of upstate New York. The idea that lower trading volumes with lackluster performance could increase risk suggested selling out, parking proceeds in cash for safety and buying back in the fall. Obviously, the adage ignores taxes with taxable accounts and the cost of buying and selling. Is the concept valid?

From roughly 1950 to about 2013, the Dow average posted lower returns May-October compared to November-April. But since 2013, seasonal patterns have not held up and those who “sold in May” generally missed out on significant upticks in markets. Why the change?

Air conditioning and laptops for one thing. You a can be cool in your office, car, home, or vacation condo no matter where you are. No longer must you call a broker to get market information or place a trade. Information is ubiquitous and trading cheap. Sadly, market participation is down. A 2017 Gallup poll showed that only 54 percent of American households owned stocks, compared to 62 percent before the financial crisis. Those who did jump in post-crisis or held on have experienced the strongest bull market recovery in history.

There’s another factor related to a long-term investment horizon. A February 2018 story indicated “84 percent of all stocks owned by Americans belong to the wealthiest 10 percent of households. That includes everyone’s stakes in pension plans, 401(k)s and IRAs, as well as trust funds, mutual funds, and college savings programs like 529 plans.” Much of those funds are monitored by professional managers with 24/7 oversight, reducing seasonal patterns.

The S&P 500 Index hit an all-time high on June 20, 2019, a strong comeback from the 4th quarter 2018 slump. In a world of instant information and high-speed computers trying to out-guess and “front run” even tiny trends, successful market timing is all but impossible. 

Most bear markets in the past have been caused to some extent by an energy crisis, or Federal Reserve action to increase interest rates to choke off runaway inflation. Inflation remains relatively benign, and interest rates are persistently low, providing little competition for stocks, especially reliable dividend payers. The benchmark 10-year U.S. Treasury note, which tends to reflect Fed policy and investor expectations, fell below 2 percent on June 21, and European yields are even lower. Dropping bond yields could indicate that investors smell recession, but that theory is suspect given the S&P 500’s record high, with the Dow average a hair below its all-time high of last October.

Mortgage rates have dropped with banks advertising 15-year loans in the 3.1 percent range, 30-year loans around 3.50 percent. Low rates are stimulating building and refinancing activity. With America now the world’s largest oil producer, we’re no longer hostage to Middle Eastern and OPEC turmoil. We won’t be repeating the gas line shortages of 1973 and 1979 anytime soon. Plus, vehicles are far more fuel efficient than they were 40 years ago.

Your investment policy should be driven by a long-range plan, not fear and emotion. Build a solid and safe “What if?” fund to get past periodic and largely unpredictable market slumps. Retirees or the “about to be retired’ should have a 3- to 5-year “paycheck fund” in federally insured savings along with perhaps some shorter-term or laddered bond holdings. A good dividend flow should be part of retirement funding strategies.

Those with long-term wealth building horizons should stay invested, taking advantage of dollar-cost-averaging to grow retirement and college savings funds. “Go away in May” (or in June, July, or August) should refer to vacation plans, not market timing strategies!

Happy summer! School will start before you know it!
