Sounds like they're saying we should sell, and that pretty much goes along w/ the doom'n'gloom we're getting everywhere:

Do Econ Fundamentals Support Today's Market? - Trish Regan, USA Today
This Hot Stock Market Is a Lot of Bull - Jonathon Trugman, New York Post
Are Markets Really Efficient As They Say? - Jeff Sommer, New York Times
