The New York Stock Exchange may add an evening trading session as early as July, Chairman and Chief Executive Richard Grasso said Monday. The world’s largest stock exchange had initially planned to extend hours in mid-2000 and is accelerating the change--in part because its rivals are doing the same. The Nasdaq Stock Market and two private companies said they might begin evening trading in a few months. Grasso said the Big Board, which is now open from 9:30 a.m. to 4 p.m., will add hours only if there is demand.
