US stocks closed little changed Thursday after a solid rally sparked by surprisingly good data on weekly jobless claims fizzled out, in part due to questions over the figures. Trading action focused on Sprint Nextel, whose shares soared 14.1 percent on news that the third largest US wireless carrier was in talks to be bought by Japan\'s Softbank. At the closing bell, the Dow Jones Industrial Average was down 18.51 points, or 0.14 percent, at 13,326.46. The S&P 500 gained 0.30 (0.02 percent) to 1,432.86, while the tech-rich Nasdaq lost 2.40 points (0.08 percent) to 3,049.38.
