Ackman already boasted that he sold dummy, when he exited the Board -- after also admitting that the CEO he brought in, Ron Johnson, is the reason company went into sharp decline in 2012, cutting all sales even Black Friday/Cyber Monday! And cutting all the classics loyal customers relied on with no significant new sources of revenue -- a pair of disasters.
-- If you're going to lie at least know enough facts that it's so easy not to find you out!
Possibly Ackman is accumulating at these low prices he caused -- maybe shorting. With his track record he'll get burned again if he is. Karma!
