The stock market is down Monday, with the Dow Jones Industrial Average down 0.57%, the Nasdaq down 0.09% and the S&P 500 down 0.47%. Today’s big movers were winners, however. The winners include a food company being taken private, a trading firm looking to sell off a major unit and a social-networking company receiving strong sales projection from a Wall Street analyst. Today’s only loser was a retailer who had its shares downgraded by Wall Street analysts.
