Summer portfolio & Sell in May

Back in 2016 I wrote about the "Sell in May and Go away" adage.

"It's probably the oldest and most well-known investment adage... Sell in May and go away, don't come back till St. Leger Day. Or in other words, sell out of the stock market in May and stay in cash over the summer, before going back in at the start of September when the St Leger Stakes horse race is run. The theory is that by doing so you avoid the more volatile summer months which historically have also tended to underperform the rest of the year."

In that article, I referenced a number of pieces of research that suggested that following the Sell in May adage over the long-term could actually be detrimental to your investment returns. But as with many seasonal trends their reliability can ebb and flow.
