Mario Tuernich, head of index trading in equity derivatives at JPMorgan in London, has left the firm. He has been replaced internally by Gareth Murphy, co-head of single stock trading in equity derivatives, said Clemens Lansing, head of flow derivatives trading, which includes single stock and index trading, in London. He declined further comment. Tuernich could not be reached.
Tuernich decided to leave JPMorgan to pursue other interests, which include sailing, said individuals familiar with the situation.
Before Tuernich's departure JPMorgan merged its index and single stock trading into one group, headed by Lansing. Previously Lansing was head of single stock trading. After the reorganization, Tuernich remained head of index trading within the group and Murphy was co-head of single stocks with Paul Leech.
