this has become rather annoying to watch not because of the price drop but the way it is being manipulated.can someone tell me who would want to sell almost 4mil between 39 and 41,what price did these guys bought in,surely holding the stock price down,it went comfortably to 41.5 and looked it can go much higher but they could not let it go,they had to bring it down so they can buy more,cnp will run but when is the big question
