I heard it was all dark pool - big block buyers - led by either Soros or Buffett - this is where you want to step in and back up the truck because all those SHLD customers are literally running across the mall to JCP, slamming their money down on the counter yelling "gotta get some of dat"
Everyday it's the same thing. Several large sell order are executed in the first half hour to drive the price down. Funds are creating fear in early trading, and buying back at a lower price in the PM.
The price of this stock is so easy to push around. High daily volume but very low volume in first half hour typically. Longs or shorts can push it the first half hour then let momentum drive on.
