Cyo,
Second, your assumption that shorts can't cover is ludicrous. GFCI is at an all time low. If the shorts sold their shares a month ago, they would have doubled their money.
Just FYI, the maximmu you can make with a short position is 100%.
Sell 100 shares of xxxx for $1 each, you get $100.
Stock goes to .001 you buy it back for 10 cents. Your profit was in effect 100% or double the money you needed to short it in the first place.
