Call it a private equity fund of hedge funds. Goldman Sachs Asset Management’s new $500 million private equity fund has bought nearly 10% of London-based hedge fund manager Winton Capital Management, Winton said.

The Goldman fund, which is also run from London by Jonathan Sorrell, will buy stakes in the general partnerships of hedge funds.

Winton did not say how much Sorrell’s fund paid for its 9.99% passive stake. The fund will have no say over the management of Winton’s funds, nor will it receive any seats on the $10 billion hedge fund firm’s board of directors. Winton does not expect to allow Goldman to boost its stake any further.
