(Kitco News) - One of the best-performing hedge funds just made gold its top holding as it increased its investment in SPDR Gold Trust by 180%, totaling $38 million by the end of Q2, according to the latest regulatory filings. Sandler Capital Management is known as one of the top performers this year after nearly doubling the year-to-date gains for the S&P 500, reported CNBC, citing Symmetric.io — a hedge-fund tracking firm. This could be a sign that the hedge fund sees more market volatility ahead as recession fears take the center stage again.
