Sell in May and Go Away


Sell in May and Go Away is an old investment adage suggesting that investors can improve their returns by selling stocks in May and returning to the market in November. This strategy is based on the historically observed pattern of stock market returns being typically weaker from May through October compared to the other half of the year. However, this seasonal effect may not apply consistently and relying solely on this adage can be risky for investors.


The phonetic transcription of the keyword “Sell in May and Go Away” in the International Phonetic Alphabet (IPA) is /sɛl ɪn meɪ ænd ɡoʊ əˈweɪ/.

Key Takeaways

  1. Seasonal Stock Market Strategy: “Sell in May and Go Away” is an old stock market adage that suggests investors should sell their stocks in May and not return until November to avoid the historically weak performance in the market during the summer months.
  2. Historical Basis: The saying originates from the historic underperformance of stocks during the summer season, specifically from May to October. It is believed that factors such as summer vacations and reduced trading volume contribute to this underperformance compared to the typically strong November to April period.
  3. Considerations and Criticisms: While there is some historical evidence to support the idea, following the “Sell in May and Go Away” strategy should be approached with caution. Critics argue that it is based on an oversimplification of market trends, and the strategy might not work as well in modern financial markets. It is important for investors to consider particular circumstances, financial goals, and tolerance for risk before deciding to follow this adage.


The adage “Sell in May and Go Away” is important in the business and finance world as it refers to a popular strategy used by investors who believe that stock markets tend to perform poorly during the months of May through October. This seasonal trend, historically attributed to investors taking summer vacations and less market activity, suggests that people should sell their stocks in May and re-enter the market in November to maximize their returns. However, the effectiveness of this strategy is a matter of debate among financial experts, with some highlighting that it is overly simplistic and not always applicable to current market conditions. Regardless of its accuracy, “Sell in May and Go Away” remains a significant strategy signaling investors to stay aware of potential seasonality in market performance.


Sell in May and Go Away is a popular adage in the world of finance and investing that encourages investors to sell their stocks during May and then re-enter the market around November. The underlying principle behind this strategy is the idea that stock market performances are historically weaker during the summer months when many traders and investors go on vacation and decrease their market activity. By following this adage, investors aim to capitalize on the market’s stronger performance months, typically observed between November and April, and avoid potential losses during the more volatile summer months. While the purpose of the Sell in May and Go Away tactic is to mitigate the risk and preserve an investor’s capital, its effectiveness remains a subject of debate among financial experts. Some argue that maintaining a long-term investment strategy, which involves regularly investing in the market and holding onto one’s investment, could yield better returns, as it minimizes the likelihood of missing out on potential growth, dividends, and other beneficial financial events. Additionally, this approach may not be suitable for all, as it requires a keen understanding of market patterns and timing, which could be challenging for novice investors. Nonetheless, the Sell in May and Go Away adage remains a popular strategy in the finance and investment sphere, reflecting the seasonal patterns observed in the stock market.


“Sell in May and Go Away” is a well-known financial adage that suggests investors sell their stock holdings in May to avoid the typically weaker performance of the stock market during the May-October period. Here are three real-world examples: 1. 2000-2002 Tech Bubble: In the early 2000s, the dot-com bubble burst, leading to a significant decline in the stock market, especially the tech-heavy NASDAQ index. Investors following the “Sell in May and Go Away” strategy would have avoided much of the downturn that occurred between May and October of those years. Had they sold stocks in May 2000 and repurchased them in November, they would have saved themselves from substantial losses during those months. 2. 2008 Financial Crisis: During the summer of 2008, the U.S. economy experienced significant turbulence due to the subprime mortgage crisis and failures of major financial institutions like Lehman Brothers. The market saw major declines, beginning in September 2008. By selling in May, investors would have avoided the turbulent period that followed, protecting their portfolios from massive declines. They could have re-entered the market in November when the market started to stabilize, or later in 2009 when it was in recovery mode. 3. 2011 European Debt Crisis: The European debt crisis caused global stock markets to decline during the typically weak period between May and October. As concerns about European debt mounted, investors saw a “risk-off” sentiment dominating the markets, leading to a downturn. Had they followed the “Sell in May and Go Away” strategy, they would have shielded their investments from the declines throughout this period and taken advantage of buying opportunities once the situation began to stabilize. Please note that these examples are historical, and past performance is not always indicative of future results. The “Sell in May and Go Away” strategy has its limitations and may not always provide optimal investment outcomes. Always consult with a financial professional before making investment decisions.

Frequently Asked Questions(FAQ)

What does the term “Sell in May and Go Away” mean?
“Sell in May and Go Away” is a popular investment strategy based on the idea that stock market returns tend to be lower during the months of May to October compared to the period between November and April. The strategy suggests investors sell their stocks in May and re-enter the market in November to capture higher returns and minimize risk.
What is the origin of the “Sell in May and Go Away” strategy?
The origins of the strategy can be traced back to an old English saying, “Sell in May and go away, do not return until St. Leger’s Day.” St. Leger’s Day refers to a horseracing event in England, which occurs in mid-September.

Is there any statistical evidence supporting “Sell in May and Go Away”?
There are several studies and data analyses that support the theory to varying degrees, with historical patterns showing that the stock market does tend to perform better during the November-April period. However, it is important to note that these patterns are not consistent across all years, and past performance does not guarantee future results.
Are there any drawbacks to following the “Sell in May and Go Away” strategy?
Yes, there are some potential drawbacks to this strategy. One major issue is that it can lead to missed opportunities if the market performs well during the May-October period. Additionally, selling and re-entering the market may incur transaction fees and taxes, which could offset any potential gains. Lastly, following such a strategy may not be suitable for long-term investors with a buy-and-hold approach.
Can “Sell in May and Go Away” be applied to other financial markets?
While the “Sell in May and Go Away” theory has its origins in the stock market, some studies suggest that similar patterns may hold for other financial markets, such as bonds and commodities. However, the theory’s effectiveness for those markets may not be as pronounced or consistent as it is for stocks.
Is “Sell in May and Go Away” a guaranteed-return strategy?
No investment strategy can guarantee returns, and “Sell in May and Go Away” should be thought of as a rule of thumb rather than a surefire method. Investors should always carefully consider their investment strategy based on their financial goals, risk tolerance, and market outlook.
