Stocks ended lower on Tuesday on disappointing earnings from electronics retailer Best Buy Co. Inc. and on worries that high oil and gas prices could curb consumer spending heading into the holiday season.

The Dow Jones Industrial Average closed down 85.50 points, or 0.8 percent, at 10,597.44. The Standard & Poor’s 500 Index fell 9.36 points, or 0.8 percent, to 1,231.20. The Nasdaq Composite Index was down 11.08 points, or 0.5 percent, at 2,171.75.

The results from Best Buy cast a long, dark shadow over the markets.

U.S. gasoline futures ended higher for the first time in three sessions on Tuesday on forecasts that inventories fell last week in the wake of refinery shutdowns caused by Hurricane Katrina.
