Institutional investors expect to invest a greater percentage of plan assets in alternative investments, according to a PricewaterhouseCoopers survey released Monday. Forty-one percent anticipate increasing their allocation to real estate, 40% to private equity, 35% to commodities and 33% to hedge funds. However, less than half report they are happy with their hedge fund portfolio performance, 67% are happy with their private equity performance with private equity portfolio performance and 57% are happy with their real estate returns with real estate portfolio returns. About one-quarter of those surveyed are happy with the hedge fund regulations, with most stating they have difficulties comparing and benchmarking performance and would like more standardized valuations. About 220 executives at pension funds and other institutional investors in North and South America, Europe and Asia were interviewed in December 2006 and January 2007.
