George Soros, the billionaire investor who has repeatedly warned of a looming financial crisis with debt-laden China at the centre of the storm, disclosed on November 14 he had invested in the largest China-focused exchange-traded fund and opened a big position in an emerging markets ETF.

The 86-year-old, who rose to fame and fortune as "the man who broke the Bank of England" by betting against sterling in 1992, kept mixed investments in gold and the S&P 500, the main index used to measure big-stock performance in the US, according to a regulatory filing.
