green, it's just the opposite, you can't buy them in small quantities. It is not worth the time for a broker to search them out and get a market maker to determine a legit bid/ask from a seller of those bonds, ie, a hedge fund in this case.
But if you came in with 100k in funds looking to buy the wamu jrs, and the broker was experienced in bonds then a price would be established and an order could be placed. Problem is no one wants them.
A bond broker takes a fee if I remember correctly and for 100k worth of bonds the procurement of said bond takes time, I would would not be surprised if the broker wanted a couple k for his fee.
Disclaimer, I have not played in the bond market for several years so things may have changed in reference to fee structure.
all imo
