This is exactly what they should have done immediately when these stocks started to make no sense. 150% moves would be maybe a rough estimate. Markets need to be protected from manipulation. Not allowing purchases from robinhood does not punish retail traders more than institutions. There was NO legitimate reason for the price on these stocks. By limiting purchases they are preventing their clients from getting into a trade that will almost certainly result in losses. "the short sellers" could very well be other retail investors. I personally shorted GME & AMC when they hit ridiculous prices (I lost money on these trades when they became 2x ridiculous)
