SOROS BET ON MARKET CRASH BIGGEST YET (Source Market Watch) Soros Fund Management increased a bear-call bet on the S&P 500 in a huge way. The fund lifted a put position — a bet the market will go lower — on the S&P 500 ETF SPY +0.31% to its biggest size yet, in terms of value and portfolio percentage, making a 605% leap over the previous quarter. Bullion Baron, who has long kept a beady eye on Soros’s SPY moves, has summed up the latest dealings. He speculated that this could be  a hedge — or Soros is really worried about something. One possible something is China, which the hedge-fund titan referred to as a global uncertainty earlier in the year, notes the Baron. As for that China unease, WSJ’s MoneyBeat reports that China bears are entrenched and see stocks headed for a big fall. One strategist says it’s not good to see that stocks there have been rallying on both good and bad economic news.
