Paulson's Gold Fund Limps Forward

Gold is up 70 percent since hedge-fund manager John Paulson turned bullish in the spring of 2009. So why has Paulson & Co.'s dedicated gold fund suffered double digit declines?

In an investor briefing to be distributed late Tuesday or Wednesday, Paulson will reveal that his gold fund fell more than 10 percent for the first two months of this year, said people familiar with the numbers. That showing falls after a 2012 in which the gold fund reportedly fell 25 percent, dragging down Paulson's Advantage and Advantage Plus funds, both of which contain gold positions, along with it.

Some investors, including Societe Generale's Lyxor platform, have abandoned the gold fund amid poor returns and lack of interest among their own clients. Yet others are committed to Paulson's gold thesis, said someone familiar with the matter, and have in fact threatened to pull their money if he backs away from it. Paulson's gold fund now manages about $900 million, this person added, and the Lyxor account only amounted to about $15 million.

Paulson's gold thesis is straightforward. In a world of quantitative easing, he believes, the yellow metal will benefit as central banks print money that is distributed throughout the economy. The new money could take multiple years to circulate, Paulson argues, but once it does, the resultant inflation will buoy the price of gold.

Paulson & Co. initiated its gold thesis in April 2009, shortly after the Federal Reserve announced plans to add $1 trillion to the financial system by purchasing longer-dated Treasury bonds and mortgage-backed securities. Gold was trading at less than $1,000 at the time.

Rather than buying physical bullion, though, Paulson bought a combination of gold-mining equities, including AngloGold Ashanti and Gold Fields. Given the quantity of yellow metal in their proven reserves and the relatively low valuations at which they were trading, stocks like AngloGold seemed a cheap entry point for a metal trading at far higher levels in the commodities markets, Paulson and his gold team believed.

In the intervening years, gold ran way up—to an all-time high of more than $1,900 in Sept. 2011. Throughout that period, Paulson toyed with the mix of mining and production stocks and a small portfolio of gold derivatives, also housed in the gold fund. But, confident of his longer-term thesis, Paulson left the overall strategy intact.

That resilience has created lots of pain of late. Ballpark estimates gleaned from Paulson's securities filings and stock prices during those periods suggest that of the six major gold-mining and production equities Paulson has held for 12 or more quarters—names like AngloGold, Gold Fields, and Barrick Gold—almost all are down by double-digit percentages since he bought them (one name, Iamgold, has fallen 60 percent). At the same time, though, gold itself has risen by an even bigger margin.

Despite the troubles, John Paulson has no plans to close down the gold fund, said the person familiar with the matter, and will play out his three-to-five year thesis regardless of any short-term issues. "I think as long as the Fed is buying, that's going to be positive for the gold price," Paulson said at a presentation at Manhattan's 92nd Street Y cultural center in January.

Volatility, however, is likely to continue—and with it, a dose of investor skepticism.
