HPNN has been REVOKED Shorting would be a great idea if it wasn't so impossible to do. Margin requirements for bankruptcy-bound penny stocks like the REVOKED HPNN make it impossible for investors to short. Looks like Petey is still dumping shares, though. He needed the flunky lawyer opinion letter so the restrictive legends could be removed and the shares could be dumped into his bogus pitch-deck hype.
