…The popular seasonal stock market saying “sell in May and go away” conveys that the stock market tends to under-perform in the six summer months compared to the six winter months but is this indeed the case?…Is this typical period of weakness in the summer months only seen in U.S. markets, or does it exist in other countries as well?

As the chart shows, advances in the S&P 500 Index in the summer half of the year between May and October are significantly weaker than in the rest of the time. However, the absolute peak in prices is not in May as the saying suggests, but rather in July…

Detailed results by country

What then is the situation in other countries? The following table shows the half-year results of the eleven largest stock markets by market capitalization.

The table above underscores that the seasonal weakness in the summer months – also known as the “Halloween effect” – indeed exists. In all countries the winter half-year was stronger than the summer half-year.

  • In two of the eleven countries, France and Taiwan, losses of more than three percent were recorded during the summer months.

The saying “sell in May and go away” infers that the stock market is seasonally weak from May to September and, as such, one should not own stocks during that period of time.
