And even if everyone had the same info, they don't all draw the same conclusions. "everyone knew" that the dollar/euro at $1.35 was just a stopping point on the way to the gutter. Then it traded back in for 2 years.
And also, not everyone is a "guy with reputation". Which is only more to support my claim that the market is not as simple as the guys in mathematical finance need to believe it is so their models are even tractable with a supercomputer. "It's the statue, man, The Statue."
