Ackman needs to remember how Jay Gould sold his gold way back when. Jay Gould knew that more gold was going to be released into the market by President Grant.
HE put out the word that he was still buying gold...had 2 brokers loudly buying for Jay Gould. He had 4 brokers silently dumping every bit of gold he owned including what the 2 brokers were buying that day.
Basically he singlehandedly influenced the market.
Ackman need some way of convincing people to buy the stock so he can get out of his position...Not sure he is clever enough to pull that off.
