I'm somewhat out of the loop. If RH is low on money due to lending it out, then they have to stop lending. But the decision was to stop allowing buy orders on GME if I read and remember that correctly. What's the issue? Don't investors deposit money into their RH accounts and then purchase the stock from that money, giving RH a commission? That should be good for RH, so I'm not getting this. I probably just miss some info, hope I'm not asking a stupid question.
