Gulp:

The big worry is that a spate of hurried sales could unleash a vicious circle within the hedge fund industry, with the sales leading to more losses, and those losses leading to more withdrawals, and so on. A big test will come on Tuesday, when many funds are scheduled to accept withdrawal requests for the end of the year.

“Everybody’s watching for redemptions,” said James McKee, director of hedge fund research at Callan Associates, a consulting firm in San Francisco. “And there could be a cascading effect, where redemptions cause other redemptions.”

What happens at hedge funds, those loosely regulated private investment vehicles, matters to just about every investor in America. Hedge funds are not just for the rich anymore. Since 2002, the industry has roughly tripled in size, as pension funds, endowments and foundations piled in, hoping for market-beating returns.
