Mixed earnings reports also weighed on stocks.
Dell fell 70 cents, 7.3 percent, to $8.86. The computer maker is struggling as consumers switch to tablets and smartphones away from PCs. Dell said that its revenue may fall as much as 13 percent in the fourth quarter. Sears fell $10.99, or 19 percent, to $47.49 after the retailer said sales at both its Kmart and Sears stores continued to tumble.
Superstorm Sandy depressed U.S. industrial output in October, while production of machinery and equipment declined sharply, reflecting a more cautious outlook among businesses, according to a Federal Reserve report.
The Fed says industrial output fell 0.4 percent last month, after a 0.2 percent gain in September. Excluding the storm's impact, production at the nation's factories, mines and utilities would have been up about 0.6 percent.
The yield on the benchmark 10-year Treasury note edged down to 1.58 percent from 1.59 percent late Thursday.
