Hedge funds and private-equity firms today are like the dot-coms in 2000: Ask for money and you'll get it. They bid up the prices of everything. The amount of money flowing is almost out of control, and it's making everything overvalued. A client of mine said it's like there are 11,000 planes in the sky and only 100 good pilots -- an accident is bound to happen. Ray Dalio, Bridgewater Associates
