In a 13-F filing three months ago, Soros' fund had puts on 1.6 million shares, valued at $299.264 at the time.
Even though he is still net long stocks, this took the short position (where he owns an option which will profit from a fall in stocks prices) on the S&P 500 from 2.96% of his Soros Funds Management Portfolio to a whopping 16.65%. (Hat tip to @BullionBarron for the heads up.)
