The Dow Jones Industrial Average Index slid 0.24% to close at 13,482.36. Rising concerns over Spain's bailout weighted down on the US blue chips. However, recent positive data from the US capped the downswing. Only three in nine sectors included in the index gained. The top-performers were oil and gas sector and health care companies. Chevron moved higher by 0.61% while Exxon Mobil shed 0.09% amid weaker energy prices. Among health care firms, Merck climbed 0.58% while Johnson & Johnson dropped 0.25%. Dragging the US stock index lower, basic materials and consumer services slid 1.55% and 0.73%. Basic materials sector plunged on signs that China's and India's demand is weakening. Alcoa and El du Pont de Nemours sank 0.67% and 1.71%. Meanwhile, Walt Disney lost 0.83%. Lenders also slumped, with Bank of America and American Express dropping 0.33% and 0.95%.
