Invest in May, depart in May: Could the traditional wisdom hold up in the current year?

"The saying 'Sell in May and go away, don't come back until St Leger's Day' has historically held weight in the financial world, and experts predict this year may be no different for markets."

Invest in May, depart in May: Could the traditional wisdom hold up in the current year?

**"Skedaddle in May, and don't bother comin' back 'til St. Leger's Day" - an age-old saying that still echoes in the financial realm, reminiscing the Doncaster St. Leger Stakes horse race in mid-September.

In simpler times, movers and shakers on Wall Street would kick back for the summer, leaving a drought in trading activity, and resulting in less-than-impressive returns. But with tech taking over, things have shifted, right?

Well, not entirely. The data shows that the saying still holds some weight.

Since 1965, the UK's FTSE All-Share index has seen a slight drop of approximately 0.2% between May and September. But history has proven that this pattern isn't consistent every year.

Last year, the "Sell in May" rule got a bit of a break, with the FTSE All-Share growing a healthy 1.7% across the summer months, despite volatility in the US and Japanese stock markets.

With increasing trade uncertainty, downside economic risks, and a false sense of security in the market, analysts predict the "Sell in May" rule might make a comeback this year.

However, outside factors such as globalization, algorithmic trading, and the unpredictability of the stock market, particularly the US markets, make this adage challenging to rely on entirely.

The chaos caused by Trump's tariffs and the end to the temporary truce could potentially escalate market volatility during the summer. But hang on, the adage has historically been less effective for US markets.

Deutsche Bank analysts pointed out that following the "Sell in May" strategy in US markets might have yielded an annual return of 9.2% since 1973, while a "Buy and Hold" strategy would have netted a 10% return.

As for Germany's DAX index, senior analyst Jochen Stanzl at CMC Markets noted that the index also shows variations in seasonal patterns, with troughs not always happening until early October.

So, while the "Sell in May" adage has some historical basis, its effectiveness has waned, particularly in the US. It's essential for investors to consider individual stock fundamentals rather than relying on blanket seasonal strategies."
