Eton Park Capital Management, the hedge fund firm led by Eric Mindich, gained 2.4 percent in July because of bets on China and U.S. stocks.
The gains brought the fund’s returns to 10.7 percent this year, according to a person familiar with the matter. Wagers on derivatives and securities in other Asian countries also added to the gains, said the person, who asked not to be named because the information is private.
Eton Park, which manages $9 billion, was started in 2004 by Mindich, a former Goldman Sachs Group Inc. partner. The firm’s main fund gained 6.4 percent in 2014 and 22 percent in 2013.
Jonathan Gasthalter, a spokesman for Eton Park with Sard Verbinnen & Co., declined to comment on the performance.
