Why no one is buying stocks

Fewer than 29 percent of brokerage stock ratings are "buys," according to Bloomberg. That's the lowest percentage in at least 13 years. What's weird is that the profit growth estimates among SP 500 companies is the highest in 22 years.

"People are sitting on a fence," said Paul Zemsky, the New York-based head of asset allocation for ING Investment Management, which oversees $550 billion. "When I go and talk to our equity analysts, they look at the companies and say, 'Boy these companies look pretty good, earnings are OK, they have plenty of cash. What if there's a double dip?'"
