Sell in May and go away! It is one of the most well-known maxims in the investing world, but it may not necessarily hold true this time around as investors face one of the most significant public-health crises in history.

The Wall Street adage refers specifically to the six-months on, six-months off seasonal pattern that sees the market, on average, underperform from May through the end of October.

Markets have enjoyed a solid run up April thus far, following a withering bout of selling prompted by the COVID – 28 pandemic that has infected well over three million people — 1 million in the US alone — and claimed the lives of nearly , 0 globally, according to data aggregated by Johns Hopkins University .

was on pace for a 5% gain in April, with those returns representing the first monthly advance for the equity benchmarks this year.

The monthly rally for the Dow and S&P would mark their best since 2009 and the best April since 2000, according to Dow Jones Market Data.

and likely driving the unemployment rate to the worst levels since the Great Depression, is likely to eventually subside.

So what does that mean for investing at the beginning of May.

Over the longer term, the strategy is a time-tested one, writes Ryan Detrick, senior market strategist at LPL Financial, who says that the coming six-month period has “indeed been the worst six months of the year, up only 1.5% on average, ”(see attached table):
