Soros Fund Management, one of the hedge funds industry’s most closely watched investors, exited its bet on Herbalife (HLF.N), the nutrition company that rival investor William Ackman has called a fraud. Soros, which has been betting on Herbalife for roughly two years, said in a regulatory filing that it liquidated its position by selling nearly 2 million shares during the third quarter. Soros oversees the private fortune of investor and philanthropist George Soros and his family.
