Forbes – Back in 2008, Warren Buffett made a bet with Protégé Partners, a fund of funds hedge fund manager, that the S&P500 would beat a group of hedge fund managers selected by Protégé. The bet officially started on January 1, 2008, and runs for a decade, ending on December 31, 2017. The performance is being measured by netting out fees, costs and expenses that go into running the hedge funds. Buffett made the bet to prove his contention that hedge funds underperform due to the fact that “costs skyrocket when large annual fees, large performance fees and active trading costs are all added to the active investor’s equation.”
