Why Merrill's CDO Sale Doesn't Mean Big Writeoffs Elsewhere [View article]
Absolutely agreed Tom. Saying every CDO needs to be written down to 22c (or 5c depending on how you view it) is like saying every stock needs to be marked down to $2 (or $10) because that's where BSC went. Ok, not the same .. but u get the idea ..
Just to give you an idea of how fragile the rating agencies models really are .. let me give you an example. Back when I was structuring CDOs, we'd have a portfolio of 100 credits we'd run through S&P's or Moody's model. It would then spit out the level of subordination needed to achieve a certain rating. Now, in most cases, one would assume that if you downgrade one of the input ratings, the level of subordination would be higher to account for the increased risk. But all that was behind these "models" was a simple Monte Carlo simulation that used the exact same seed every time -- meaning you could game the models to give you a LOWER subordination when downgrading a credit!!! This means you could achieve a higher rating by having a worse portfolio, all else being equal!
This is the same model investors have relied on for billions upon billions of dollars of investments!
