Understanding ‘Sell in May and Go Away’
“Sell in May and go away” is not just a catchy rhyme but a strategy based on historical observations in the stock market, particularly noting stocks’ underperformance from May to October. Initially highlighted by the Stock Trader’s Almanac, this approach advises investors to sell their equity holdings in May, to reinvest in November. This method supposedly skirts the historically sluggish summer markets.
Historical Context and Performance Insights
This strategy stems from when agricultural cycles heavily influenced market liquidity, impacting stock performance due to capital flows at the start and end of the farming season. Although less relevant today, traces of this pattern seemingly persist, intriguing modern investors and analysts alike.
According to Fidelity Investments, since 1990, the S&P 500 has averaged about a 2% gain from May to October, starkly contrasting with approximately 7% from November to April. However, notable exceptions like the 2020 market disruption due to COVID-19 suggest that the pattern does not hold universally nor annually.
The Theory Behind Seasonal Divergence
It’s hypothesized that investment flows due to financial industry bonuses and the mid-April U.S. tax filing deadline contribute to this phenomenon. However, it’s crucial to note huge outliers like the October 1987 stock-market crash, which have left a lasting imprint on statistical averages, skewing perception towards a seemingly robust pattern.
Why Caution is Advised Against Blindly Following ‘Sell in May’
The primary pitfall of historical patterns is their unpredictability moving forward. As the saying gains popularity, its effectiveness may diminish due to the anticipatory actions of savvy investors, who might begin selling in April and buying back in October, thereby eroding the pattern’s potential benefits.
Fluctuations year-to-year and other overriding economic or global factors often dilute the seasonal influence. For instance, during the unforeseen 2020 pandemic markets, following the ‘Sell in May’ adage would have led to missed opportunities during the subsequent recovery months.
Conclusion: To Sell or Not to Sell?
Whether to “Sell in May and go away” should depend on more than just historical precedent; it necessitates a nuanced understanding of current market conditions, personal investment goals, and a good dollop of skepticism towards one-size-fits-all strategies.
