(Bloomberg) — Nasdaq OMX Group Inc. hired Adena Friedman back from Carlye Group LP and promoted Hans-Ole Jochumsen, establishing two presidents who report directly to the chief executive officer.
Friedman, rejoining Nasdaq as president of the companys global corporate, information and technology solutions business, returns after a stint as chief financial officer of Carlyle, the private equity firm. She started her career at Nasdaq and went to Carlyle in 2011.
Executive Vice President Jochumsen becomes president of the global-trading and market-services operations, and will continue to report to CEO Bob Greifeld, the exchange said in a statement.
The new management structure comes about six months after Eric Noll, viewed as a potential successor to Greifeld, left to become CEO of ConvergEx Group LLC. U.S. equity markets are in transition as regulators look at practices including high- frequency trading and as Nasdaqs two closest rivals change ownership.
The New York Stock Exchange, now owned by IntercontinentalExchange Group Inc., plans to pare back the types of orders customers can place in response to criticism that their proliferation gives high-frequency traders an unfair edge. Bats Global Markets Inc. merged with Direct Edge Holdings LLC to form an entity with 20 percent of daily equity volume.
