Wall Street was short-changed of any clarity over a rate-hike timeline after the release of minutes from the July meeting showed a split Federal Reserve. Stocks fluctuated through the afternoon before settling slightly higher. Officials showed relief that risks to the economic recovery had eased, though were divided on whether that meant the Fed was ready to hike rates. Two members pushed for a rate hike in July. Marcato Capital has upped pressure on Buffalo Wild Wings (BWLD) to shake up its C-suite. The firm, which owns a 5% stake, said the company needs new talent on the board and at management levels. Barnes & Noble (BKS) fell 12% after chief executive officer Ronald Boire exited the position. The book seller said Boire had not been "a good fit" and that executive chairman Leonard Riggio would hold the position until a permanent replacement was found.
