WSJ on the retail investor boom

After shying away from active investing for much of the past decade, millions of Americans, hunkered down at home because of Covid-19, became day traders in 2020...  It is estimated that more than 10 million individual investors opened new brokerage accounts in 2020, according to Devin Ryan, director of financial-technology research at JMP Securities.  Last year the trends from 2020 accelerated.  JMP Securities estimates that a further 15 million Americans signed up for brokerage accounts in 2021.
