Welcome to Finance Insider, Business Insider’s summary of the top stories of the past 24 hours.

In the summer of 2015, Penn State’s endowment invested $US50 million in Pershing Square Capital, a high-profile hedge fund run by New York City billionaire Bill Ackman.

The endowment, one of the largest held by a university, invested as the fund was coming off years of stellar performance. Two years later, the fund has had a reversal of fortune. The Pershing Square International fund reported a loss of 16.6% in 2015 and a loss of 10.2% last year. The fund gained 1.83% through mid-June of this year.

At those rates, a $US50 million investment in 2015 would be worth about $US38 million now. That doesn’t include annual fees, of about 1.5% of the assets (about $US750,000 on the initial amount), paid to the hedge fund.

The Penn State-Pershing Square situation highlights a turning point for the hedge fund industry. Once a cottage industry financed by the rich, hedge funds are now largely funded by public universities and pensions, which oversee the retirement money of the nation’s teachers, firefighters, and police officers.

Here’s how teachers, firemen and college endowments ended up enriching America’s hedge fund billionaires.
