One clue that this rally is different comes from the last is Robinhood. Once the favorite trading platform of meme traders, Robinhood is in trouble. As stock markets fell and Covid stimulus cash dried up, so did Robinhood's business. Its number of active users has dropped from 22 million to 14 million, and its stock trades at around $10 after cresting at close to $60 a year ago after it went public. Last week, Robinhood announced it would lay off 23% of its staff after it posted a 44% decline in revenues.
