Last week was upbeat for Wall Street. The S&P 500, the Dow Jones and the Nasdaq gained about 0.94%, 0.78% and 1.11% last week. The stocks basically ignored myriad of concerns including inflationary pressures and rising Delta variant of COVID-19 cases and continued rallying. However, tech stocks specifically surged probably due to the fact that COVID environment boosts the demand for stay-at-home stocks which are largely dependent on technology (read: S&P 500 to Roar Higher: ETFs to Ride the Rally).

Against this backdrop, below we highlight a few ETF areas that won last week.

Clean Energy

The environmental, social and governance (ESG) investing category continues to remain one of the most popular arenas among investors. ESG funds saw attractive inflows already this year. U.S. President Joe Biden is known as promoting clean energy. The United States once again entered the Paris climate accord – adopted in 2016 – in the Biden era. Biden wants the United States to achieve a 100% clean energy economy and net-zero emissions, no later than 2050. All these initiatives helped boost ESG investing.

Zacks Names "Single Best Pick to Double"

From thousands of stocks, 5 Zacks experts each have chosen their favorite to skyrocket +100% or more in months to come. From those 5, Director of Research Sheraz Mian hand-picks one to have the most explosive upside of all.

It’s a little-known chemical company that’s up 65% over last year, yet still dirt cheap. With unrelenting demand, soaring 2022 earnings estimates, and $1.5 billion for repurchasing shares, retail investors could jump in at any time.

This company could rival or surpass other recent Zacks’ Stocks Set to Double like Boston Beer Company which shot up +143.0% in little more than 9 months and NVIDIA which boomed +175.9% in one year.
