While the stock has gained 2.6%, the Securities Exchanges industry registered a 1.8% rise.CME Group’s improving volumes are driven by a solid operating leverage, helping it maintain an enormous market share. The company holds about 90% market share of the global futures trading and clearing services. Expansion of futures products in emerging markets, plus increase in non-transaction related opportunities and OTC offerings should continue to contribute modestly to the top-line growth in years ahead. Efforts to expand and cross-sell through strategic alliances, acquisitions, new product initiatives as well as global presence should also drive growth.Zacks RankCME Group presently carries a Zacks Rank #3 (Hold).
