Marc Faber expects the S&P to drop as much as 15%, which will give Bernanke the green light to another round of Treasury purchases. "We may drop 10-15%. Then QE2 will come, QE4, QE5, QE6, QE7 - whatever you want. The money printer will continue to print." But he considers a stock correction healthy in view of how far equities have come from the March 2009 lows.
