The Dow Jones Industrial Average Index slid 0.17% to close at 13,102.99 on Tuesday. Mounting uncertainty over further Fed actions in view of positive US data releases created pressure on the US blue chips. Moreover, lack of progress in the ECB bond-purchasing program also weighted down on the Dow Jones Index. Only one in nine economic sectors included in the index jumped. Oil and gas companies soared as Hurricane Isaac threatens to stop oil production in the Gulf of Mexico. At the moment, about 78% of oil production in region is halted by the tropical storm. Chevron and Exxon Mobil climbed 0.55% and 0.41%. Meanwhile, lenders were mixed, with American Express gaining 0.24% and Bank of America falling by 1.36%. The biggest losses poised telecommunications and technology sectors. AT&T and Verizon Communications dropped by 0.62% and 0.21% while Cisco Systems and Hewlett-Packard shed 0.72% and 1.80%.
