While shorting is in theory possible, and some accounts if you have enough money can short despite the rules that say NO...... There really are no shorts here. Check the short interest on OTC site and you will only see some fail to deliver due to the 3 day rule. So... .taking talk of shorts out...... You are left with retail, the company, and toxic debt holders. Take your pick on who was to blame today.
All in all, this will run again, but sure was annoying today to see the fail.
