The top-level fall out from the arrival of new Nasdaq CEO Robert Greifeld continues with the departure from the US stockmarket of vice chairman David Weild, who has left the firm "to pursue other interests".
Weild, who joined Nasdaq in 2001, led the corporate client group and was a member of the operations management committee.
His departure follows the replacement last week of Dean Furbush as executive vice president of transaction services and William Harts as executive vice president of corporate strategy by Greifeld appointees Glen Wolyner and Christopher Concannon.
Richard Ketchum, Nasdaq deputy chairman and president quit the week before Greifeld arrived from SunGard to take over the helm of the troubled stockmarket from Wick Simmons.
The management shake-up almost certainly foreshadows a wider round of staff cuts as Greifeld seeks to stem the recent decline at Nasdaq and wrest back market share lost to alternative trading systems.
