NEW YORK (MarketWatch) -- Crude futures remained higher Wednesday after data showed business conditions improved in October across a narrower group of companies in the U.S. nonmanufacturing sectors. The Institute for Supply Management nonmanufacturing index stood at 50.6% in September. Readings above 50% indicate more firms said business is improving than said it's worsening. It's the second straight month above 50% after 11 months of contraction. December crude rose 0.7% to $80.16 a barrel in recent trading on the New York Mercantile Exchange.
