First, I agree Ackman's comments on CNBC were very positive, but I don't think they are the reason for the volume surge in the closing hour yesterday. Ackman's interview started after the closing bell. Now, could he have told a few powerful friends he was going to make those comments ahead of time and they acted on it before the close? Possibly, I guess.
Keep an eye on the volume/price action over the next few weeks. If it mimics what happened in late Sept. to early Nov. '13 then there's a very good chance you have another major player or two taking a large stake in FnF commons. If that happens chances are that player is or is very close to at least one of the following....Trump, Ackman, Berkowitz, Icahn, or any of the other usual suspects tied to Trump that may play a role in how the gov't handles FnF moving forward.
