Gill, who goes by Roaring Kitty on X and YouTube and by DeepFuckingValue on Reddit, was at the center of the 2021 GameStop saga. Shares of AMC, GameStop's fellow meme stock, surged by nearly 80% on Monday and 30% on Tuesday. What's changed is Roaring Kitty is tweeting, and not even really about a company. If you bought GameStop or AMC shares in 2021, it might not be a bad time to consider selling some to break even. Roaring Kitty is back, and people are tossing their money into the GameStop slot machine.
