Nasdaq OMX Group promoted Tom Wittman, head of the exchange operator’s options markets, to run its three stock exchanges as well. Wittman has been running Nasdaq’s options marts since 2008 when Nasdaq bought the Philadelphia Stock Exchange.
As part of a management change, Brad Vopni, previously Nasdaq’s head of U.S. equity product management and strategy, has left the company. Vopni spent nine years at Nasdaq. The news was first reported by Dow Jones earlier today.

In a memo, Eric Noll, Nasdaq’s head of transaction services in the U.S. and U.K., told employees: “I believe unifying the leadership around our U.S. equity and derivatives offerings at Nasdaq OMX will help sharpen our focus and allow us to better serve our customers.” Wittman reports to Noll.
