According to a recent paper by Dr. Everett M. Erlich even a modest allocation to hedge funds could improve
Hedge funds have evolved from an elite investment to a standard component of investment portfolios, and in so doing, offer institutional investors, such as pension funds, the opportunity to improve returns. The modeling performed for this analysis suggests that a modest allocation to hedge funds would improve the returns to public pension funds by approximately $13 billion annually. Moreover, the track record of recent years further illustrates that hedge funds have not been a source of greater systemic risk — rather than “too big to fail,” they are generally not an important source of systemic risk.
