Global markets are entering May after a remarkably strong April, prompting investors to reconsider the traditional “sell in May and go away” strategy. Analysis suggests this adage may no longer hold true, with historical data indicating potential gains during the summer months. However, investors must also navigate ongoing concerns about inflation and a busy earnings season.

Is the "Sell in May" Strategy a Relic of the Past?
As May begins, investors are questioning the traditional wisdom of "sell in May and go away." This strategy, aimed at avoiding summer's historically lower returns, is facing scrutiny after a record-breaking April for several stock markets. Will this year buck the trend, or is it time to heed the old advice?
April delivered exceptional gains across global markets. Europe's STOXX 600 and Germany's DAX achieved their best monthly performances since January of last year. Italy's FTSE MIB saw an even more impressive rally, marking its strongest month since January 2023. In the US, the S&P 500 and Nasdaq also logged their best monthly performances in approximately six years.
Challenging Conventional Wisdom
Recent history suggests the "sell in May" strategy may be losing its effectiveness. Over the past decade, the S&P 500 has averaged a 1.5% return in May, a 1.9% increase in June, and a robust 3.4% gain in July. Deutsche Bank's analysis of European markets indicates that, in 25 out of 39 years, simply holding stocks outperformed the "sell in May" approach.
Earnings Season and Global Risks
The coming weeks will be filled with earnings reports from major European companies, including Unicredit, HSBC, Commerzbank, Shell, and Novo Nordisk. However, investors must also navigate global risks, including cautious signals from central banks regarding persistent inflation. Jerome Powell (Federal Reserve), Christine Lagarde (ECB), and the Bank of England have all expressed concerns about inflationary pressures.
Key Events This Week
- Monday: U.K. market holiday, April PMI data from across Europe
- Tuesday: Earnings from Unicredit, HSBC, AB Inbev, Ferrari and AMD
- Wednesday: Earnings from Novo Nordisk, Infineon, BMW, Diageo and Disney
- Thursday: Earnings from Shell, Rheinmetall, Maersk, BMPS and AirBnB
- Friday: Earnings from Commerzbank, IAG
Despite the positive momentum, investors should remain agile and consider the potential for market volatility. As Deutsche Bank concludes, the "Sell in May" strategy offers no more certainty than a coin toss.
