US stocks fell slightly as a dip in oil prices dragged energy companies lower, but for the week stocks ended sharply higher. Trading was quiet Friday as investors looked ahead to weekend meetings on the global economy and oil. Oil fell 3% and made the energy sector worst performer by far in the Standard & Poor's 500 index. Utility companies led the gainers. The Dow Jones industrial average fell 28 points Friday, or 0.2%, to close at 17,897. The Dow finished the week up 1.8%. The S&P 500 fell 2 points, or 0.1%, to 2,080. The Nasdaq composite fell 7 points, or 0.2%, to 4,938. (More Dow Jones stories.)
