Is Gold Overpriced Relative to Other Commodities?VW Staff
Gold stocks are quite popular among hedge funds these days, and with good reason. John Paulson, who is very bullish about gold, made $5 billion by betting on gold in 2010. As of December 31, 2011, the largest position in the 13F portfolio of his Paulson & Co was the gold exchange-traded fund (ETF) SPDR Gold Trust (ETF) (NYSEARCA:GLD) in which Paulson had over $2.6 billion invested. Besides Paulson, there were 55 other money managers bullish about SPDR Gold Trust (ETF) (NYSEARCA:GLD) In total, they had $8.2 billion invested in the position.
Another gold ETF, Market Vectors Etf Trust (NYSEARCA:GDX) was also popular with hedge funds last year. It was held by 41 hedge funds at the end of last year. In addition to ETFs, hedge funds were also bullish about companies engaged in producing gold, such as Barrick Gold Corporation (USA) (NYSE:ABX) and Newmont Mining Corporation (NYSE:NEM). There were over 40 hedge funds with these two positions in their 13F portfolios at the end of 2011. For instance, David Einhorn’s Greenlight Capital Re, Ltd.(NASDAQ:GLRE) had $60+ million invested in Barrick while Jim Simons’ Renaissance Technologies had nearly $90 million invested in Newmont. Other gold stocks with significant hedge fund interest are Goldcorp Inc. (USA) (NYSE:GG), Kinross Gold Corporation (USA) (NYSE:KGC), Allied Nevada Gold Corp. (NYSEAMEX:ANV), and AngloGold Ashanti Limited (ADR) (NYSE:AU)
But, is gold truly worth investing in? Or, is it overpriced relative to other commodities? Let’s check it out by comparing the historical prices of the gold and commodity indexes.
We are going to use spot gold prices and two commodity indexes: S&P GSCI (Goldman Sachs Group, Inc. (NYSE:GS) Commodity Index) and CCI (Thomson Reuters Equal Weight Continuous Commodity Index). S&P GSCI is a broad-based index mainly weighted in energy (80%), agriculture (10%), industrial metals (6%), and precious metals (2%). CCI is comprised of 17 commodity futures that are continuously rebalanced to maintain equal weighting. Unlike GSCI, which can overweight the energy sector, CCI provides relatively even exposure to all commodity subgroups (energy 18%, metals 24%, soft commodities 29%, and agriculture 29%).
Gold vs. GSCI
We collected daily data points of spot gold prices and GSCI from January 8, 1991 to March 23, 2012 and plotted the values we obtained (see the graph of gold price vs. GSCI). Gold price and GSCI tracked each other closely before late 2008. After that, the price of gold went up rapidly while GSCI grew at a relatively slow pace. As a result, the gold-price-to-GSCI ratio has gone up to a higher level in recent years. As of March 23, 2012, the gold-price-to-GSCI ratio is 2.37, 25% lower than its peak of 3.18 on February 23, 2009 but still 35% higher than its historical average of 1.75.
Gold vs. CCI
Gold looks a bit overpriced compared with other commodities when using GSCI, an index has higher weight on energy. Now, let’s compare the gold price with an equally weighted commodity index, CCI. Similarly, we collected daily data points of gold prices and CCI from December 29, 1978 to March 23, 2012.Gold prices grew abnormally high in January 1980 to about $850 per ounce due to high inflation, high oil prices, and the termination of the direct convertibility of the dollar to gold. The price of gold has also gone up much faster than CCI since late 2008. Therefore, the gold-price-to-CCI ratio has a peak of 3.02 on December 7, 2011 and it also reached 2.93 earlier on January 21, 1980. As of March 23, 2012, the ratio is 2.89 which is 74% higher than its historical average of 1.66 (see the gold/CCI graph).
Overall, the price of gold has been on an uphill trend over the past decade, but it grew much more rapidly than other commodities only in recent years. Gold market is very liquid and it also doesn’t cost a lot to store it. Gold supply is also pretty inelastic which makes it a good long-term play on inflation. These may be the reasons why investors preferred gold over other commodities. Our calculations showed that gold is overpriced relative to other commodities. This doesn’t mean that gold prices are going to go down though. Considering that there were no supply side shocks after September 2008 that would explain the 100% increase in gold prices relative to commodities we think investors would be better off by betting on commodities and shorting gold.
