Hedge fund Paulson & Co in Q1 maintained its stake in SPDR Gold Trust, the world's biggest gold-backed exchange-traded fund as bullion prices rebounded from their biggest annual loss in 32 years in 2013, while PIMCO dissolved its gold ETF investment.

George Soros raised his stake in Barrick Gold Corp and gold mining companies ETFs, suggesting the big names in hedge funds took advantage of lower gold prices to increase positions in the precious metal used by many as a hedge.

Investors pay close attention to the quarterly filings by Paulson and other notable hedge fund managers because they provide the best insight into whether the so-called "smart money" has lost faith in gold as a hedge against inflation and economic uncertainty.
