I was looking for some penny stocks that were going parabolic for some time. Example for them was ANY, ABIL, ... blah blah I was sure those stocks will go down again because the move was non sense. I believe it was pump and dump. I was considering to see if IB has those stocks for shorting but seems not. The stocks are low float (less than 5 millions share) I was asking myself, which Broker would have such stocks for shorting! Note: I am not going to trade such stocks but it is just interesting question for me.
