Stocks pressed higher late Wednesday as investors digested minutes from the latest Fed meeting. The Nasdaq flipped to an 0.4% gain, the S&P 500 added 0.2% and the Dow 0.1%. Volume continued to track mixed compared with Tuesday, higher on the Nasdaq and lower on the NYSE. Stocks’ initial reaction was muted, but picked up steam as Fed Officials largely brushed aside a weak economic start in 2015.
