U.S. Stocks Fall as Best Buy Drops Before Bernanke Speech

U.S. stocks fell after disappointing forecasts from Best Buy Co. and Campbell Soup Co. while investors awaited a speech from Federal Reserve Chairman Ben S. Bernanke to gauge the prospect of continued stimulus.

Best Buy slid 11 percent, the most in almost a year, after saying it will work to keep pace with competitors’ discounts in the holiday season, hurting fourth-quarter profitability. Campbell Soup fell 6.2 percent after cutting its profit forecast. Home Depot Inc. gained 0.9 percent after boosting its earnings forecast as rising home prices spurred homeowners to splurge on renovations. Tyson Foods Inc. climbed 4.6 percent for a sixth day of gains as sales beat analysts’ expectations.
