US stocks were little changed in opening trade on December 19, 2014 as the market sought to keep alive a winning streak since December 17, 2014 that has recovered most of December's losses. Five minutes into trade, the Dow Jones Industrial Average stood at 17,779.62, up 1.47 points (0.01 percent). The broad-based S&P 500 added 2.60 (0.13 percent) at 2,063.83, while the tech-rich Nasdaq Composite Index slipped 4.30 (0.09 percent) to 4,744.09. Wall Street stocks have skyrocketed the last two days, spurred by a Federal Reserve meeting Wednesday at which the US central bank said it would be "patient" before raising interest rates.
