This is an index-based ETF that tracks small-cap and micro-cap mining companies that derive a significant portion of their revenue or assets from copper mining and related businesses. It provides exposure to junior miners, which have large growth potential within the copper industry value chain.

It suits investors who want exposure to rising copper demand and the commodity cycle, and whose risk appetite is high enough to tolerate the heavy volatility of small and mid-sized mining stocks.

It is a passively managed (index-tracking) ETF run by Sprott.

The fund holds small and mid-sized mining companies that derive a significant portion of their revenue or assets from copper mining, exploration, development, and production, according to the index inclusion criteria. It tracks the index through full replication, and holds a few dozen stocks, combining the growth potential and volatility that are characteristic of junior mining stocks.

• Concentrated in small and mid-sized junior copper mining companies
• Pure exposure to the single copper theme

Assets under management (AUM) stand at $138.3M, and the total expense ratio is 0.75% per year.

Volatility tends to be higher than for ETFs centered on large mining stocks, but the fund can show a resilient performance when copper prices are rising.

The fund is closely tied to copper prices and the commodity cycle, and because it holds small and mid-sized mining stocks, it tends to swing widely during periods of market volatility. Returns tend to be highly volatile depending on copper supply and demand and the economic cycle.

Expectations of rising copper demand from electrification and the energy transition support interest in thematic ETFs. However, during commodity price corrections, fund flows can swing sharply, so performance differs greatly depending on the market environment.

Its strengths are pure exposure to the copper theme and growth potential, while its weaknesses are the high volatility of small and mid-sized mining stocks and concentration risk.

Among the products shown in the table, COPX covers the same copper mining theme but has a higher weighting in large mining stocks, so its volatility is relatively lower, while GDX, GDXJ, and SIL are commodity ETFs with a different theme, focused on gold and silver miners. As a direct substitute for copper miners, the large-cap-focused COPX is the closest. Investors who want exposure to copper itself without going through miners can also look at copper futures-based products, and those who want broader commodity diversification can also consider XME, a broad metals and mining ETF.

These are the points to review before investing in COPJ. Copper theme ETFs carry strong growth expectations, but it is important to check carefully in advance the volatility characteristic of small and mid-sized mining stocks, sector concentration, and the burden of the expense ratio.

Copper price movements and the high volatility of small and mid-sized mining stocks are the main variables for short-term performance. During commodity corrections, losses can be larger than for broad-based ETFs, so position sizing needs to be managed.

It is a suitable satellite holding for investors who want to bet actively on rising copper demand and the energy transition theme. To reduce volatility, investors can consider the large-cap-focused COPX, and for higher growth exposure, COPJ.
