According to U.S. financial media outlet CNBC and other foreign news sources on May 3 (local time), there are growing concerns that investors may incur losses if they continue to adhere to this strategy.

The "Sell in May" strategy is a traditional investment approach where investors sell stocks in May to avoid low returns and light trading volumes during the summer, and then re-enter the market in November.

However, in recent years, analysis suggests that this strategy is no longer effective. The JP Morgan trading desk pointed out that over the past 10 years, the S&P 500 index, the leading U.S. stock index, posted an average gain of 1.5% in May and 1.9% in June. The average return for July was even stronger at 3.4%.

A similar phenomenon has been observed in the European stock markets. Deutsche Bank noted that for the Euro Stoxx 600 index, the "Sell in May" strategy underperformed the simple buy-and-hold approach in 25 out of the past 39 years, offering no statistical advantage.

In particular, this year there are numerous factors that justify ignoring seasonal investment strategies. For example, in April, global stock markets experienced a rally. In the U.S., both the S&P 500 and the Nasdaq achieved their highest monthly returns in about six years. The Euro Stoxx 600 and Germany's DAX index also recorded their best performance since January of last year.

A substantial portion of this record-breaking bull market is attributed to a shift in direction by the U.S. Trump Administration. Investors found reassurance as the U.S. began seeking an exit strategy from the Middle East conflict. Corporate earnings have also remained robust. Additionally, the U.S. economy has shown greater resilience than expected amid energy shocks, which is seen as another positive factor.

However, concerns about global inflation resulting from the ongoing war are considered a risk factor. Central banks in major economies such as the U.S. and Europe have taken a cautious stance in determining benchmark interest rates due to inflationary pressures. The U.S. Federal Reserve, the Bank of Japan (BOJ), the European Central Bank (ECB), and the Bank of England (BOE) all held their rates steady last week.

CNBC noted, "With multiple market factors at play, investors must choose between traditional and more unconventional strategies," adding, "However, as Deutsche Bank points out, the 'Sell in May' strategy offers about as much certainty as a coin toss."
