Wyoming Retirement System, Cheyenne, is searching for an absolute-return manager to run between $50 million and $100 million, said Thomas Mann, director. It will be the $5 billion fund's first absolute-return allocation; the search is the result of an investment committee recommendation to further diversify and decrease investment volatility. Mr. Mann said manager candidates must have at least $2 billion in assets under management and at least $500 million under management in absolute-return strategies. Funding will come from rebalancing; no managers will be terminated. Interviews will probably take place March 17, with a selection soon after. Mellon's Human Resources & Investor Solutions is assisting.
