I'm guessing that some shorts did cover and the rest wished they had at 8.25.
Shorts are in trouble now. Too many and not much time. If they all bail in the next few days the price will go through the ceiling. If they hold, they take a chance on really getting burned - twice. Once on earnings and once on the following short squeeze.
The Fed action today means that earnings will now get a lot more attention and not be summarily dismissed out of hand.
Shorts have gotten pulled in and now their retreat has been sealed off.
Let's watch and see how they handle the conundrum...
