Bullish Buffett buying stocks

Warren Buffett said he's buying U.S. stocks and, if prices stay attractive, his personal investments, as distinct from his stake in Berkshire Hathaway, will soon be wholly in American equities.

Writing in the New York Times, he said he's following this principle: Be fearful when others are greedy, and greedy when others are fearful.

While short-term stock movements can't be foretold, the likelihood is that the market will recover before the economy or general investor sentiment rebound, and "if you wait for the robins, spring will be over," Buffett said.
