U.S. Stocks Fall as Crude Slump Weighs on Energy Shares

U.S. stocks fell, after the Standard & Poor’s 500 Index posted its first back-to-back weekly retreats since October, as the continuing selloff in crude pulled down energy shares before the start of corporate earnings.

Energy shares tumbled 2.8 percent, the most among 10 groups in the S&P 500, as crude dropped 4.7 percent. Tiffany & Co. lost 14 percent after the jewelry retailer lowered its annual forecast after sales declined during the holiday. SanDisk Corp. fell the most in almost six years after reporting preliminary results below its own estimates.
