NYSE Euronext (NYX) acquired American Stock Exchange (Amex) in 2008 to expand its equities, options and exchange-traded funds (ETFs) trading business. Recently NYSE announced plans to sell the majority of its stake in the Amex stock options market to seven companies -- including top banks, trading houses and brokerages. With this move, the company hopes to increase its trading volumes by giving major brokerages an incentive to bring their business to Amex. Major competitors are Nasdaq OMX (NDAQ), CME Group (CME), BATS Global and Direct Edge.
