Is the DOW headed for a fall soon?

Even as stock prices edged upwards into new high water territory during the debt ceiling debate, there are those who question their fundamentals and their staying power at these high prices. Yale University finance professor Robert Shiller ( Noble Peace Prize winner last week ), and author of the 2000 best seller, Irrational Exuberance, sees stocks getting too expensive relative to their earnings. According to his clinically adjusted price/earnings ratio- he sees stocks are again dangerously overpriced and poised for a fall in the future.
