The AUMI ETF tracks the Solactive Global Pure Gold Miners Index and focuses on global companies that earn revenue from gold mining activities. Because it invests in the shares of gold mining companies rather than in physical gold itself, company-specific operating conditions can affect performance in addition to commodity prices.

It suits investors who are willing to accept the business risks of the gold mining industry and want to add gold-related equity exposure through a diversified ETF.

It is a passive (index-tracking) ETF managed by Themes ETFs.

The AUMI ETF prioritizes holding the index constituents at similar weights, and it may use sampling depending on market access and trading conditions. Its portfolio is also affected by the production, costs, mine operations and resource development environment of individual mining companies such as AU, AEM and GFI.

• Index exposure centered on companies with a high share of revenue from gold mining
• A passive structure that reflects both the share prices of global miners and the industry environment

Assets under management (AUM) stand at $19.9M, and the total expense ratio is 0.35% per year.

Thematic industry ETFs can show performance trends that differ from physical gold, depending not only on underlying commodity prices but also on the cost management, production plans and capital spending of the companies they hold, as well as on equity market risk appetite.

Gold mining share prices can become highly volatile as expectations for gold prices, currency values, the interest rate environment, production costs and mine operating issues all interact. In particular, investors should keep in mind that a change in gold prices may not immediately translate into a change in an individual miner's profitability.

Fund flows into gold mining ETFs can be influenced by perceptions of the commodity market, the currency environment, geopolitical variables and shifts in risk appetite. Regional operating conditions, environmental regulations, labor costs, and exploration and development costs also feed into investment decisions across the industry.

It offers equity exposure concentrated in the gold mining industry, but it is a product that reflects gold price risk and company operating risk at the same time.

In the comparison table, the GDX ETF offers similar exposure centered on large gold mining companies, while the GDXJ ETF can be sensitive to the volatility of smaller gold miners. The fee burden of the GDX ETF and the GDXJ ETF is higher than that of the AUMI ETF. The COPX ETF focuses on the copper mining industry, the URA ETF on uranium-related industries, and the SIL ETF on silver mining companies, and these also carry a higher fee burden than the AUMI ETF. They share the common trait of being resource extraction industries, but the price variables of the underlying commodities and the business environments differ.

Before investing, you should check together the nature of the asset as gold mining company stocks, the difference between gold prices and company earnings, trading conditions and the distribution policy. The gold mining industry can be affected by regional mine operations and the regulatory environment, so it is hard to judge based on commodity prices alone.

Falling gold prices, rising production costs, mine development delays, environmental regulations, exchange rates and geopolitical variables can all weigh on miners' profitability and share prices at the same time. Given the ETF structure, the market price can differ from net asset value, and because of its concentration in gold mining, short-term losses could also widen.

The AUMI ETF can be considered by those who want equity exposure centered on gold mining companies, but it should be understood as an industry investment that includes company operating risk, rather than as something expected to match the performance of physical gold. Before holding it for the long term, you should review costs, trading conditions, industry concentration and currency exposure as a whole.
