Until 2007 I would've agreed with you. But judging by recent history, most rating changes seem to me much more reactive in nature than proactive. Or at least they can be explained easily this way, while the reasoning that 'they know more than we do' is a bit harder to support after they got blindsided by the global recession back then.They don't get paid to make guesses and gambles. The fact that they have only just now changed the rating suggests that they have confidence that certain indicators of future activity are surely not going to turn out well and good.
Anyone can take the 50/50 gamble of being right and calling the market (up or down) at any time...being right for the wrong reasons is great in Vegas but makes for a poor analyst or ratings house. These guys get paid to be right for the right reasons and if they get that part wrong then they are out of business themselves.
