The month of May has been solid for the U.S. equity stock market, unlike the popular adage “Sell in May and Go Away” despite the rising tension between the United States and China. This is especially true given the reopening of the economy, and progress in drug-treatment and vaccine development for COVID-19.

The easing of coronavirus-induced lockdown restrictions has started to propel demand and is likely to revive economic growth. Large fiscal and monetary stimulus flowing into the economy has added to the strength. The central bank has plenty of ammunition to rescue the economy from a deep slowdown, indicating a potential recovery in the second half of the year. The Fed would expand existing lending programs or start new ones if required.

Notably, the S&P 500 has climbed 4.2% this month. That said, some sector ETFs have outperformed the market. Below we have highlighted five such ETFs that have raked in substantial gains in May and could be better plays if the trend prevails.
