Investing in particular gold stocks gives exposure to movements in price of gold, but also to other factors affecting the gold mining industry, as well as company-specific strengths and weaknesses. This is why investors have to bear in mind the trends in the gold market as well as the mining industry, and wisely select appropriate stocks. One way to avoid the problem of selecting the promising shares is to invest in an index of gold mining companies [such as the HUI, XAU and/or GDX. That being said there are considerable differences and pros and cons which this article outlines.]
The comments above and below are excerpts from an article by Arkadiusz Sieroń (SunshineProfits.com) which has been edited ([ ]) and abridged (…) to provide a faster and easier read.
There are several options available for investors, but the two most watched indices are:
- the NYSE Arca Gold BUGS (Basket of Unhedged Gold Stocks) Index (called the HUI Index)
- a modified equal dollar weighted index of 14 companies involved in gold mining which do not hedge their production beyond 1.5 years. It was developed in 1996 and is still traded on the NYSE.
- Philadelphia Gold and Silver Index (called the XAU Index).
- a capitalization-weighted index of thirty precious metal mining companies that has been traded on the Philadelphia Stock Exchange since 1983.
- Another closely observed gold mining index is the NYSE Arca Gold Miners Index, which is a modified market capitalization weighted index comprised of precious metal mining companies. Its performance is tracked by the VanEck Vectors Gold Miners ETF (GDX), which – as an exchange-traded fund – is an interesting option for gaining exposure to gold miners.
There are three main differences between the HUI and XAU indexes:
- The HUI includes only gold miners who do not hedge their gold production beyond 18 months,
- The XAU consists of companies who use such hedging, and includes both gold and silver miners…[and] also includes companies that mine other metals, such as copper, and for whom gold is only a byproduct. For example, Freeport-McMoRan is the largest component of the XAU Index (it makes up 8.45% of it), but its gold sales generate only 10% of the company’s revenues. Therefore, it seems that the XAU Index is a less reliable indicator of stocks’ sensitivity to movements in gold prices than the HUI Index.
- The indices attach different weights to particular companies. For example, the three largest companies constituting the HUI Index make up 40% of it, while the same companies amount to just 24% of the XAU Index. It means that the HUI is more diversified and better reflects trends in medium-cup companies.
This is why there will be differences in indices’ performance. Indeed, as you can see in the chart below, although the two indices are positively correlated, the HUI Index is often slightly more sensitive to movements in gold prices than the XAU Index.
Chart 1: The price of gold (yellow line, left axis, London P.M. Fix), the HUI Index (green line, right axis), and the XAU Index (purple line, right axis) from 1996 to 2016.
…[The chart] makes perfect sense, as the HUI Index includes only gold miners and excludes companies using long-term hedging, reducing the sensitivity of bullion’s price volatility. For example, during the financial crisis in 2008, the HUI index collapsed 70.6%, the XAU Index plunged 68.2%…[but] gold bullion fell around 30%…Investors should always remember that the leverage provided by gold stocks…magnifies both gains and losses from the bullion market, as in our example. It also shows that gold behaved as a safe-haven asset when compared to mining stocks during the financial crisis, despite the initial price decline.
The conventional wisdom about the leverage offered by gold stocks, however, does not hold in the long term. As one can see in the chart above, bullion outperformed both indices of gold mining companies in the long run. The price of gold is now more than three times higher than in 1996, while the HUI Index is only 8.7% higher and the XAU Index actually lost almost 40% of its value in the last twenty years. It means that the gold mining equities performed relatively poorly compared to gold. Of special interest is the fact that their performance was also weak when compared to the general stock index, such as S&P 500, through that period.
- Mining shares are correlated with the price of gold, but they should be viewed as a different asset class than bullion and related derivatives.
- Gold is insurance against market turmoil with no counterparty risk, while mining companies clearly have such exposures.
- Investors can limit the distinctive risks associated with particular mining businesses by investing in gold stock indices…[but remember that] they do not track the price of gold accurately since they include companies producing other metals or do heavy hedging.
- The general stock market trends affect mining stocks in a different way than they do for gold. The mining stocks also behave distinctly during business cycles.
- Despite the conventional wisdom about the leverage offered by gold stocks, historical analysis shows that in the long-run bullion outperformed mining equities.
…For long-term investors who would like to get full exposure to gold – especially for some insurance against black swan events – it makes sense to buy bullion, futures or ETFs rather than to invest in gold miners. Investors who want to invest in gold shares should consider active trading rather than adopting a “buy-and-hold” approach.
