Thinking about selling equities in May and going away? Well, here we offer a different perspective on the old adage discussed in another recent post. Analyzing seasonal trends in equity and industry sectors can help identify stock categories that could potentially outperform the broad index during the month. We are encouraged by two sectors’ seasonal tendency to outperform the S&P 500 Index during the month of May over the last 20 years; a month when the index has on average been modestly higher for equity investors, generating positive returns 60% of the time. It should be noted that nonseasonal factors still influence performance and should not be ignored.
The table below highlights sectors’ average over- and under-performance versus the S&P 500 during May since 1997, as well as the top-performing industry groups over the same period:
As detailed in the figure above, the consumer staples and healthcare sectors have shown the best relative strength in May over the past 20 years, but if you’re looking for a more targeted strategy, the second chart within the figure analyzes the industries that comprise consumer staples and healthcare.
Consumer Staples Sector Has Outperformed Broad-Based Stocks by Average of 1.38% Since 1997
While the consumer staples sector has outperformed the S&P 500 by 1.38% on average, with a high of 11.9% and a low of -4.37% since 1997, tobacco, beverages, and food products were the three S&P 500 industry groups that helped drive the sector’s average outperformance.
Healthcare Sector Has Outperformed Broad-Based Stocks by Average of 0.6% Since 1997
Looking at the healthcare sector, it has outperformed the S&P 500 by 0.6% on average, with a high of 7.8% and a low of -3.3% since 1997; with the primary industry drivers of the sector’s seasonal outperformance having been biotechnology, life science tools and services, and health care providers and services.
While the S&P has tended to post positive returns in May, seasonal analysis can help to identify which sectors and industries may fare better, particularly if volatility increases.
