Insiders probably loaned out tons of their shares. Would be a pretty sweet return and no need to dump. Especially on CCME where the rates were so high.
All the extended halt stuff is more than ridiculous. Totally unacceptable. Nasdaq acts like a third grade exchange here. Give them 3 days to come up with a proper 10k or put them on the pinks where they belong.
IB charges interest on short positions, but many brokers don't .... I've never been charged interest by Ameritrade, but of course it's tougher to borrow hard to get shares from them.
