I think the problem is that a lot of people speak as if the equity markets lead the economy, when the reverse, long term is true.
I can't be too bullish on equities unless I see real strength in the U.S. economy - and I'm not talking about strength in the low wage service sector job market.
Also, I was real bullish back in June of 06, because of a bunch of high quality companies were showing up on my screens as really good values - low P/Es, low debt, nice cash flow- now, bubkus. There is literally nothing coming up other than troubled companies like homebuilders and lenders. And the ones that were coming up back in June of 06 have literally all doubled in share price in the last 7 months.
