Esto es lo que dice un abogado de finanzas en Nueva York sobre S&P, no he podido aguantarme:
"Look, I know these S&P guys. Not these particular guys — I don’t know John Chambers or David Beers personally. But I know the rating agencies intimately. Back when I was an in-house lawyer for an investment bank, I had extensive interactions with all three rating agencies. We needed to get a lot of deals rated, and I was almost always involved in that process in the deals I worked on. To say that S&P analysts aren’t the sharpest tools in the drawer is a massive understatement.
Naturally, before meeting with a rating agency, we would plan out our arguments — you want to make sure you’re making your strongest arguments, that everyone is on the same page about the deal’s positive attributes, etc. With S&P, it got to the point where we were constantly saying, “that’s a good point, but is S&P smart enough to understand that argument?” I kid you not, that was a hard-constraint in our game-plan. With Moody’s and Fitch, we at least were able to assume that the analysts on our deals would have a minimum level of financial competence.
I’ve seen S&P make far more basic mistakes than the one they made in miscalculating the US’s debt-to-GDP ratio. I’ve seen an S&P managing director who didn’t know the order of operations, and when we pointed it out to him, stopped taking our calls. Despite impressive-sounding titles, these guys personify “amateur hour.” (And my opinion of S&P isn’t just based on a few deals; it’s based on countless deals, meetings, and phone calls over 20 years. It’s also the opinion of practically everyone else who deals with the rating agencies on a semi-regular basis.)"
