David Puth, the former head of FX and commodities at JPMorgan, has resurfaced after nearly two years out of the market. He has been appointed to the new position of head of investment research, securities finance and trading activities for State Street. He will report to Jay Hooley, president and chief operating officer of the Boston-based bank and will sit on the company’s operating group. Puth spent many years at what was originally Chemical Bank, going through several mergers and takeovers to end up at JPMorgan. After he left the bank in November 2006, he founded risk management and advisory group Eriska; he also joined Icap’s board as a non-executive director in November 2007.
