The average hedge fund investor earned about 6 percent annually from 1980 to 2008

From the New York Times today:

The average hedge fund investor earned about 6 percent annually from 1980 to 2008 — a hair above the 5.6 percent return they would have made just holding Treasury securities, according to a study published this year in The Journal of Financial Economics.

So why would large investors pay hedge funds billions of dollars in fees over the years for those returns? The answer highlights the financial problems at the country’s largest pensions.

As waves of workers prepare to retire, pensions find themselves in a race against time. Short of what they need by an estimated $1 trillion, according to the Pew Center on the States, public pensions are seeking outsize returns for their investments to make up the gap. And with interest rates hovering near zero and stock markets gyrating, the pensions and others are increasingly convinced that hedge funds are the only avenue to pursue.

“Even with the short-term ups and downs, at the moment there is not a credible alternative with the same risk profile for pensions,” said Robert F. De Rito, head of financial risk management at APG Asset Management US, one of the largest hedge fund investors in the world.

Hedge funds, once on the investing fringes, have become a mainstay for big investors, amassing huge amounts of capital and accumulating more of the risk in the financial system.

The effect of this latest gold rush into hedge funds is unclear. Some argue that the hedge fund industry’s rapid growth — it has quadrupled in size over the last 10 years — has depressed returns. Others, meanwhile, wonder whether the bonanza in one of the most lightly regulated corners of the investment universe will have broader, less clear implications.
