Ratings business

A lot of focus is placed on companies' credit ratings, and I wonder how much the relationship of a company and its assessor has on its final rating. I have a friend who worked in Moody's and lamented that they were quickly losing market share due to their less liberal view of credit scores in comparison to S&P. And it's a bit worrying to think of how things will change if the ratings model is flawed, but I guess we can't really tell. Changes in ratings will affect the company's stock price, corporate bonds, convertibles issued, etc...but to what extent?

Just interning and look, you are already talking about a new greek - change in the drivative price / change in rating. !!

Yes, rating firms are to an extend shams.Just like old equity research during the internet boom days.

Also, there are just a very few players in that area...it has to mature.

anonymous: S&P and Moody's are so established I don't see how it can be worthwhile to have a piece of the pie. I wonder if they actually contribute, in one way or another, to the subprime crisis.
