European index provider Stoxx has announced changes in its senior management.

Dr. Hartmut Graf, previously head of the index business at the German stock exchange, Deutsche Boerse, joins Stoxx as Chief Executive Officer, replacing Ricardo Manrique, who is leaving the company. Patrick Valovic, who was previously director of business operations at Stoxx, becomes CFO.

In November 2009, Deutsche Boerse and SIX Swiss Exchange announced the acquisition of Dow Jones’s one-third share in the index provider (reported on IndexUniverse.eu here), with Deutsche Boerse acquiring a controlling (50% plus one share) stake.

A new board of directors has also been appointed, with two members joining from the SIX group, one from Deutsche Boerse and one from Swiss law firm Lenz and Staehelin.
