U.S. stocks are overbought, says reknown perma-bear Marc Faber, and any more near-term gains are going to be big trouble for the market. As we continue to move higher, the probability of a crash becomes higher as well. The next crash, he says, could be worse than the one that crushed world markets in 2008. "The next crisis could lead to a deflationary bust. And a bust in governments. In other words, we may have a total collapse in confidence in the system."
