only a few chinks yet in the ABX.HE.AAA

these tranches work differently than most people think.

it's not that one group of mortgages is more highly rated than another.

the losses in a mortgage pool are layered

the BBB- tranche gets the first 20% of the losses in a pool of mortgages

BBB get the next 20%

A gets the middle 20%

AA get the next 20%

and AAA gets the top 20%.

Just the fact that the AAAs are starting to weaken means that the market realizes that there is a possibility that the first 80% in a pool are all going to be bad.

When that happens the market will be in meltdown mode.
