There were alot of crazy moves late on Friday - 10-30% moves in the last 20 minutes til the end of the day.
Many heavily shorted stocks that spiked at EOD. ATPG was up 50% at one point.
ATPG, AXAS, ZNGA, USU, UEC, EGLE, and all the solar stocks SOL, STP, HSOL, TSL, YGE - all spiked at end of day.
I'm sure there are many more ... the action in ATPG looked to me like a margin clerk was buying at any price. It really looked like someone was getting liquidated on the short side.
