Investment Face-Off: Sell in May or Hold?

A deep dive into the popular investment strategy and how it compares to the classic ‘Buy and Hold’ approach

Introduction

The catchy phrase ‘Sell in May and go away’ has captured the imagination of investors for decades. It suggests that by selling stocks in May and returning to the market in November, investors can capitalize on the historically weaker performance of equities during the summer months. But is this strategy always the best choice, or is the tried and tested ‘Buy and Hold’ approach a better option? In this article, we’ll reveal some surprising discoveries made from our analysis, comparing these two strategies across different periods since 1980.

Key Discoveries

Buy and Hold is a long-term winner: When considering the entire period from 1980 to 2022, the ‘Buy and Hold’ strategy consistently outperforms the ‘Sell in May and go away’ approach. This implies that long-term investors might be better off sticking to the traditional buy and hold strategy.

Here we can see the performance metric table. We see that buy and hold outperform buy and hold but have 39% drawdown vs 19% drawdown. Sharpe Ratio 0.56 for the buy and hold and 0.61 for the sell in may strategy.

Performance metric by Period

Times have changed: Our analysis shows that the ‘Sell in May and go away’ strategy has outperformed the ‘Buy and Hold’ approach only since 2000. This suggests that the seasonal investing hypothesis may not be universally applicable, and its effectiveness can vary over time.

Economic growth plays a crucial role: A key factor influencing the performance of the two strategies is the overall economic growth during different periods. Our analysis reveals that during the strong economic growth period between 1980 and 2000, the ‘Buy and Hold’ strategy delivered superior returns.

Slower growth, better for ‘Sell in May’: Conversely, during periods of slower economic growth, such as 2000–2022, the ‘Sell in May and go away’ strategy demonstrated better performance. This suggests that more conservative strategies might be more effective during periods of economic uncertainty.

What Does This Mean for Investors?

The choice between the ‘Sell in May and go away’ strategy and the ‘Buy and Hold’ approach depends on various factors, including your investment horizon, risk tolerance, and the overall economic climate. Here are some key takeaways for investors:

Know your investment goals: Understand your financial objectives and time horizon before choosing an investment strategy. While the ‘Sell in May and go away’ strategy might provide better returns in some periods, it may not be suitable for long-term investors or those with a lower tolerance for risk.
Diversify your portfolio: Regardless of the strategy chosen, always diversify your portfolio to minimize risk and maximize long-term returns. Spread your investments across various sectors, geographical regions, and asset classes to reduce the impact of market volatility.
Stay informed and adapt: Regularly review your investments and make necessary adjustments based on market conditions and your personal circumstances. Staying informed and adapting your approach can help you stay on track and make the most of your investments.

Conclusion

Our findings reveal that the ‘Sell in May and go away’ hypothesis has shown better performance since 2000, while the ‘Buy and Hold’ strategy has proven to be a more consistent performer over the long run since 1980.
