Stocks soared 2% Wednesday in the first trading of 2013, after Congress' last-minute passage of a plan to avert the brunt of the so-called fiscal cliff. The Dow Jones industrial average was up 234 points, or 1.8%, to 13,338 shortly after the opening bell on Wall Street. Wednesday morning's rally follows the Dow's 1.3% jump late in trading on New Year's Eve on signs of an emerging deal between President Obama and congressional leaders.
