Value investing has been shown to work over the long term.
Have a read of David Dreman or Gallea and Patallon, both of which give evidence from long term studies that investing in stocks with Low PE, Low PCF, Low PTBV and High Dividend Yield will beat the market.
Sure there will be periods where it wont.
America is in so much pooh at present that I doubt any long strategy will work. Your stocks by historical terms are still way over valued, and there are similarities to Japan in the early 90s.
I expect the Dow to fall to around 4000 over the next year or two.
Your President is trying to shift the emphasis away from domestic issues by flexing the military might (I actually think America and Britain my Country are right to go and sort out Saddam despite little public appetite).
So please don't tell me value investing doesn't work, I have had wonderful success with it even during the UK stock market turmoils over the past three years (Market fell three years in a row, first time since the 1920/30s). It just isn't as easy to pick a winning stock. My advice, stick to the big guys on rediculous low PEs with good Divi's. At the very least you should limit the downside.
