Heavily shorted mortgage provider Rocket Companies saw its stock surge on Tuesday, in an eye-popping move reminiscent of the rallies that powered GameStop and other so-called meme stocks earlier in the year. Shares of Rocket, the parent company of Quicken Loans, closed up 71.2% at $41.60 after being halted several times for volatility. The outsized move puts Rocket among the stocks that have experienced wild gyrations after becoming a focus of investors on sites such as Reddit’s WallStreetBets, where mentions of the company have multiplied in recent days.
