Calpers, the largest pension fund in the U.S. representing 1.6 million California public employees, plans to liquidate $4 billion of investments in 30 hedge funds. Calpers sees the hedge funds as too costly with fees of about 2% of investments and 20% of profit, and too complex, lacking the ability to scale up for a pension fund of its size. Hedge funds have done poorly in the current investment environment where index funds have performed well.
