ZURICH, Sept 29 (Reuters) - U.S. investment bank JP Morgan's head of Switzerland, Nick Bossart, is moving to Rothschild & Co (ROTH.PA) to lead its Swiss advisory business for mergers and capital market transactions, two people familiar with the situation told Reuters. With Bossart, the French investment bank wants to expand its market share in Switzerland. During this time, he made JP Morgan the third-largest investment bank in Switzerland after Credit Suisse (CSGN.S) and UBS (UBSG.S). Before joining JP Morgan, he worked at Deutsche Bank (DBKGn.DE) and UBS. JP Morgan had said in July that Bossart was leaving and would be replaced by Reinout Böttcher.
