UBS Warburg has added veteran mortgage-backed securities trader Michael Hirschberg to its collateralized mortgage obligation trading effort in New York. Hirschberg joins from Bear Stearns, where he worked for 12 years, beginning as a summer intern on the fixed-income trading floor. Hirschberg will trade trust IO/PO bonds and head up all MBS derivatives trading, according to his new boss, Dave Martin. Martin says the position is newly created, and a response to customer demand for more mortgage derivatives. He will be a managing director.
At Bear Stearns, Hirschberg was a senior managing director, reporting to mortgage trading chief Jeff Mayer. A trader at Bear Stearns says his trading duties have been allocated among the remaining traders.
