There is almost no volume on the preferred shares, so they are probably tightly held. WAMU preferred shares traded for 1.5 to 3 cents on the dollars for three years and commons are getting some distribution now as well, if their POR is being confirmed.
It's not that more money will come here every day and you can watch this over some period. If enough money is suddenly flowing in, which seems to be the gamble here, both preferred and common shares can profit at the same day. If it's not enough, you will see only the preferred shares rise. And that will probably be the end of the story, unless an examiner will be appointed on the appeal, but that is not very likely.
