"Try to sell a CDO tranche, these days: you can't. "

In an earlier post, I mentioned that Felix Salmon argues that Credit Default Swaps won't be the humongous bother they're supposed to be. I suppose that constitutes optimism today. A much more worrying problem are CDO tranches. Like the difference in bother between a prostate exam at the doctor and a sigmoidoscopy, I suppose.

A Collateralized Debt Obligation tranche, according to Felix:
1) Can't be priced.
2) Can't be sold.

Yes, well that's not good.

In the interest of simplifying them unfairly, let's call them a bunch of bundled crap. If we want to be more technical and use set theory, let's say it's a set of bundled crap. I don't suppose that's very helpful.

How about a basket of ten objects, each priced differently every day, and, on any given day, the prices of some of the objects are unknown. Calling Martin Gardner or Raymond Smullyan. I'm not much of a puzzle man myself, so that's the best I can do for now.
