New York: Someday, the post-pandemic equities rally is going to end. When it does it will take a lot of newly-christened stock bulls with it. Their refusal to bend has been the signature fact of the stock market for at least 12 months, putting a floor under four other selloffs in 2021 alone that look just like the one that has sheared almost 3 per cent off the S&P 500 Index since Thursday. Whether the devotion of retail investors is enough to turn the tide again is the biggest question in markets right now. "There's a lot of very young people in the accumulation phase," said Dan Egan, managing director of behavioral finance and investing for robo-adviser Betterment, who added that younger investors in particular have used selloffs as buying opportunities. "If they have any excess cash sitting around, they're going to use it to buy in."
