Sell in May and Go Away: Debunking the Stock Market Myth

The phrase “Sell in May and go away” is a well-known adage in the world of finance, suggesting that investors should exit their stock holdings during the summer months and re-enter the market around Halloween. This strategy is based on the historical observation that stocks tend to perform better during the colder months compared to the warmer months. However, recent data and expert opinions suggest that this adage may not hold true in the current market environment.

Historical Performance of Stocks

According to historical data, the S&P 500 has averaged a return of about 3% annually from May to October, compared to about 6.3% from November to April. This difference is significant, but it is not a reliable predictor of future performance. The winter months do not always see higher returns than the summer months, and there are many years when the summer performance was strong or even outpaced winter returns.

For instance, in 2020, the summer returns were an impressive 24%, while winter returns were negative at -7.7%. Similarly, in 2009, summer returns were 21.9%, compared to winter’s -9.4%. These examples highlight that automatically following the “sell in May” strategy could result in missing out on substantial gains in specific years.

Why the Strategy May Not Work

Financial advisors caution against embracing a sell-in-May strategy. The rationale behind this adage is that stocks tend to exhibit modest performance from May through October, with stronger gains emerging in the fall. However, this strategy is not without risks. Historically, the S&P 500 Index has seen an average increase of 6.9% in the six months following November 1, with positive returns in 61 of the last 80 instances. Conversely, the index has posted an average gain of just 1.7% during the same six-month period starting May 1.

Moreover, stocks have a tendency to perform more robustly at the beginning and end of the year. The S&P 500 has yielded an average return of 11.65% since its inception as an index of 500 stocks in 1957. Had investors only invested during the November through April period, they would have missed out on a significant portion of these returns.
