I was watching closely because I sold U's to buy more P's at that time. And I remember being annoyed that the U's had dropped much further relative to how much the P's had dropped.
So I was getting less value for the U's I sold, and then had to buy P's at a relative premium.
But I'm very happy I made that switch!
I got many more shares in WMIH than if I had kept the U's, and I also got more P escrows--which are uncapped!
