There is absolutely nothing that prevents them from shorting until reg sho kicks in. Once they’re flagged for that they’re unable to short anymore.
They’ll exhaust every option possible in a situation like this. They’re continuing to short in an effort to buy some time. Before the reg sho kicks in.
I find that quite peculiar also..... if they’re short, and they know they’re in trouble, why do they keep digging their own grave...that doesn’t make sense.
