The trading floor at Weeden & Co.'s Greenwich, Conn., headquarters is designed to foster teamwork, cooperation and communication among the full-service institutional broker's 75-plus traders, sales traders and assistants on the floor, and about 25 other traders in its regional branches in Boston, San Francisco and Chicago. The floor services Weeden's 1,500 institutional clients with NYSE/Regional, Nasdaq/OTC and program trading. To handle the growing volume of international trading, Weeden recently added a 24-hour desk that is home to eight to 10 sales and trading personnel. And by the end of 2008, Weeden expects to add options and convertible bond trading expertise to its portfolio of services.
