Like LBHI, I traded the WAMU preferreds years ago. At some point I backed away thinking the easy money had been made. I have not looked at in years. As I recall when I looked at it last I thought it was over. Could be wrong.
I have traded COPP and have a small position currently.
I have both preferreds lehman and wamu, gave releses these days blackout of any useful news at COOP board. However i think it was better to sell Pq when price was $90. Now it is endless wait with gift of crona free for all! No signs of any shareholder payment. It is amzing how uk holders got paid in full and nothing for north Americans!
