Right but they didn't do anything except offer trades. The thing about selling shorts they couldn't cover makes sense, but just for "acting stupidly" seems silly.
These are pros who are paid very well to have a clue. It is not silly if "acting stupidly" is described in writing, such that all parties adequately understand when the hammer is likely to come down. I am sure a lot of traders push the envelope and "drive 71 in a 65 mph zone". But it still not silly to give the guy driving 81 a ticket.
sorry, i wasn't sure how detailed to be, but by 'acting stupidly' I meant unintentionally selling shorts they couldn't cover in a way that made the action illegal.
