After a strong first quarter for stocks, some April showers rained down as the S&P 500 fell about 4% last month. Hopefully those showers will bring some flowers in May, despite the widely cited stock market adage, “Sell in May and go away.” There is some merit to this old adage because the S&P 500’s best six-month returns have, on average, come from November through April, and its worst between May and October (recall bear markets often end in October). Still, historically the index has gained an average of 1.8% from May through October — hardly worth avoiding.

The first quarter is in the books, and it was an excellent one for stocks. The S&P 500 index rode a resilient U.S. economy, easing inflation, rising corporate profits, and anticipation of summertime rate cuts from the Federal Reserve (Fed) to solid gains in March, the fifth straight winning month, and the best first quarter since 2019.

History suggests staying the course. Since 1950, the S&P 500 has risen 93% of the time in the 12 months following a five-month streak, with an average gain of over 12%. And down years are rare after strong first quarters. So, while stocks are due for a pullback, as the choppy start to April suggests, it’s extremely difficult to sidestep a 5–10% decline. It’s tough to make a case for a big drop — one that might make sense to try to avoid — because of healthy market fundamentals.

Strong starts to years tend to signal more gains ahead, so this calm market may not precede a storm. In fact, when the S&P 500 has been up in January and February, it has gained an average of 11% over the rest of the year and has been higher in 26 out of 28 cases.
