GMO Flows Turn Negative - An Ominous Sign for Risk Taking [EconomPic]
I have a ton of respect for the way in which GMO manages money (their guts to be massively contrarian if that is their view) and I think their thought leadership is about as good as it gets in the industry. That said, I have long had an issue in the way in which they think about investor behavior
