U.S. stocks fell, giving the Standard & Poor’s 500 Index its biggest decline of the year, as political uncertainty in Europe fueled renewed concern about the debt crisis and American factory orders rose less than forecast.
All 10 groups in the S&P 500 fell at least 0.4 percent. Chevron Corp. lost 1.1 percent after UBS downgraded its recommendation on the stock. Wal-Mart Stores Inc. dropped 1.7 percent as JPMorgan Chase & Co. cut its rating on the stock. Herbalife tumbled 4.5 percent after a report the company is under investigation by the Federal Trade Commission.
