Considering the traditional financial advice, is it advisable to offload our stocks in May given the popular saying?
Rewritten Article:
Let's talk about that old saying, "Sell in May and go away"... You know, the one that crops up every spring in investment chats. This phrase, believed to be around since at least 1935 according to the Financial Times, proposes investors should ditch their stocks in May and return in November. But hang on a minute, before you jump on the bandwagon! This ancient advice might not be as golden as it seems in today's globalized markets.
The theory behind this saying is known as the "Halloween effect". Many researchers have found better stock market performance between November and April. A massive study conducted by professors Zhang Yi (Nottingham University Business School in China) and Ben Jacobsen (TIAS Business School in the Netherlands), featuring 114 markets and over 300 years of data, backs this seasonal bias. They conclude this tactic outperforms the "buy and hold" strategy by around 4%. But wait, those promising averages don't tell the whole story.
Deutsche Bank reveals that this strategy would have been less profitable than holding onto shares in 24 out of the last 38 years. It only truly shines during extraordinary times like 1998 or 2022. In the last ten years, it has failed more than it has succeeded, with a loss of 1.6% in 2024 if you followed the advice.
As a quick fix, diversifying with European bonds enhances the results slightly with an annualized performance of 11% since 1998. But even then, this strategy only outperforms the "buy and hold" strategy in 13 out of 27 years. In the American market, the same applies: the "Sell in May" approach has failed 30 times out of the last 52 years. So, should you sell in May or not? Deutsche Bank answers, "It's like flipping a coin," while it's up to you whether the coin flip is worth it.

The LowdownThe "Sell in May and go away" adage has some historical weight but struggles to maintain its edge in today's complex, algorithm-driven financial landscape. Keep these main points in mind:
- Historical Performance: Back in the day, stock markets noticeably underperformed during the summer months, leading to the saying's popularity. The S&P 500 averaged about 1.8% return from May to October, compared to a stronger 7% return from November to April.
- Recent Market Behavior: Recent years have exhibited inconsistent adherence to this pattern. For example, in 2020, the S&P 500 rallied about 15% during the summer months following the pandemic lows, while in 2022, it dropped nearly 20% due to inflation worries and the Federal Reserve's actions. In 2025, mixed performance has been observed across sectors.
- Globalization and Algorithmic Trading: Global economic shifts, unconventional monetary policies, and rapid market dynamics have disrupted history's patterns. Central bank actions, government spending, and global politics are now considered more significant factors than seasonal trends.
- Sector-Specific Performance: The strategy's effectiveness varies by industry. Cyclical sectors such as energy and materials tend to follow the pattern, while defensive sectors and technology stocks usually defy it.
- Algorithmic Trading: Algorithmic trading can swiftly address market changes, potentially mitigating the impact of seasonal trends. This rapid response can result in more consistent market activity throughout the year.
In conclusion, the "Sell in May and go away" strategy carries a rich history, but its effectiveness in today's market is debatable. Market experts advise caution, suggesting that current factors might counteract typical seasonal downturns. Therefore, this strategy may not be as reliable in today's volatile and dynamic global market situation.
- In light of the discussions about seasonal investing strategies, it is worth noting that the label "Sell in May and go away" might not be as profitable as it once was in today's complex and algorithm-driven stock market known as finance.
- As the trend of globalization and algorithmic trading continues to disrupt historical patterns, the traditional advice surrounding the selling of stocks in May and returning in November may not always outperform investment strategies that hold onto shares throughout the year, especially in sectors like technology or defensive sectors.
