Is COPJ a Buy? What to Consider in 2026
Last updated July 2026
Short answer
The case for COPJ is simple: low-cost, diversified exposure to Nasdaq Sprott Junior Copper Miners Index at a 0.75% expense ratio, anchored by names like FDY, TKO, ATYM. If that is the exposure you want and you do not already own most of it through another fund, COPJ is a strong core holding. The catch is concentration in its top names and overlap with broad-market funds you may already hold. Whether it is a buy comes down to whether you want Nasdaq Sprott Junior Copper Miners Index and at what cost. Not a recommendation; Walnut is not an investment adviser.
What are you buying with COPJ?
COPJ tracks the Nasdaq Sprott Junior Copper Miners Index, holding mid, small, and micro-cap companies focused on copper mining, exploration, and development. The fee is 0.75%. Versus the large-cap Sprott Copper Miners ETF (COPP), COPJ's key difference is its focus on junior miners, which are earlier-stage, more speculative, and far more volatile.

What's the case for COPJ?
COPJ is the Sprott Junior Copper Miners ETF. It tracks the Nasdaq Sprott Junior Copper Miners Index, holding around 70 to 80 small, mid, and micro-cap copper miners and explorers such as Ero Copper, Ivanhoe Electric, and Solaris Resources. The fee is 0.75%. It suits aggressive investors who want high-beta, early-stage exposure to the copper theme. The obvious peer is the large-cap Sprott Copper Miners ETF (COPP); COPJ is far more volatile.
In its favour: it gives you Nasdaq Sprott Junior Copper Miners Index exposure in one ticker at a 0.75% expense ratio, which is simple to hold and cheap to own.
What should you weigh before buying COPJ?
- Cost vs alternatives: 0.75% is the fee; compare it to funds tracking a similar index.
- Concentration: check how much of COPJ sits in its largest holdings (FDY, TKO, ATYM).
- Overlap: if you already own a broad-market fund, you may already hold much of this.
- Tracking scope: COPJ only gives you Nasdaq Sprott Junior Copper Miners Index; it will not capture what sits outside that index.
How do you decide if COPJ is a buy?
The useful question is rarely “will COPJ go up?” It is “does this exposure fit my plan, at a cost I am happy with, without doubling up on what I already own?” Walnut connects your real brokerage so you can see exactly how COPJ would overlap with your current holdings, analyze it by chatting through Claude or ChatGPT, and place any trade yourself. You stay in control.
The bottom line on COPJ
The bottom line: COPJ is a low-cost core building block for Nasdaq Sprott Junior Copper Miners Index exposure, not a tactical bet on a single name. If you want Nasdaq Sprott Junior Copper Miners Index exposure and the 0.75% fee is competitive for you, it does its job well. If you already own that exposure through another fund, adding it mostly doubles a fee without adding diversification. Decide from your goal and your existing holdings, not from where the market sat last week. Walnut is not an investment adviser.
