ETF Comparison: VanEck Gold Miners ETF (GDX) Versus VanEck Junior Gold Miners ETF (GDXJ)

GDX versus GDXJ: Total Cost of Ownership

On headline expense ratios, the two ETFs are tied. Both charge a 0.51% expense ratio, which translates to an annual fee drag of $51 on a $10,000 investment. That level is higher than broad sector ETFs, but it is typical for industry-specific and niche exposure funds.

The difference shows up in trading costs. GDX

has a much tighter 30-day average bid-ask spread of 0.016%, compared with 0.039% for GDXJ

GDXJ

+1.43%

. That makes GDX cheaper to trade, particularly for active traders who expect to move in and out of positions.

Verdict: When expense ratios and bid-ask spreads are considered together, GDX narrowly comes out ahead in total cost. For long-term buy-and-hold investors, the difference is minimal, but for active traders, GDX has a clear advantage.

GDX versus GDXJ: Methodology and Holdings

Despite similar names, these ETFs target very different parts of the gold mining industry. This results in a disparate basket of holdings and sensitivity to gold prices.

GDX

tracks the MarketVector Global Gold Miners Index. The portfolio holds 36 companies and is market-cap weighted, which naturally tilts it toward large, established producers. The fund is concentrated in the materials sector and represents what many investors think of as the core gold mining industry.

GDXJ

tracks the MVIS Global Junior Gold Miners Index. It also holds 36 companies, but with much greater exposure to small and mid-cap miners. The ETF carries a higher trailing 12-month yield of 2.1%, compared with 0.66% for GDX, though that yield can be volatile and less predictable.

Geographically, both ETFs are Canada-heavy, with more than half of assets tied to Canadian-listed miners. That is not surprising given Canada’s role as a global hub for mining companies. Both also have exposure to the U.S. and Australia. It is worth noting that many Canadian miners are dual listed.

Concentration is another key difference. The top 15 holdings account for 65.7% of GDX

, versus 54.27% for GDXJ

GDXJ

+1.43%

. While GDXJ appears more diversified by weight, the underlying companies are generally more volatile, being largely mid and small-cap stocks.

GDX offers broad exposure to the full spectrum of the gold mining industry. Holdings include large producers such as Agnico Eagle Mines, Newmont, and Barrick, alongside streaming and royalty companies like Franco-Nevada and Wheaton Precious Metals.

GDXJ leans much further into smaller operators. Junior miners may still be scaling production, expanding reserves, or even operating without meaningful output. Many are capital-intensive and speculative, relying on exploration success to justify valuations. The fund still holds established names such as Pan American Silver, Equinox Gold, Alamos Gold, and Royal Gold, but still skews small-mid cap.

Verdict: GDX works well as a broad, leveraged play on gold prices. GDXJ offers more torque, but that leverage cuts both ways. I think for the average investor, GDX is the easier option to understand once they become familiar with spot gold ETFs.

GDX versus GDXJ: Risk and Return

Both ETFs have delivered strong returns in recent years. Over the past five years, GDX

posted a cumulative return of 185.28%, compared with 159.54% for GDXJ. Over shorter periods of three and one year, GDXJ

GDXJ

+1.43%

has outperformed, reflecting stronger moves among smaller miners during recent rallies.

Despite this performance, both ETFs have experienced sustained net outflows over the past several years, with GDX seeing larger redemptions. Investor behavior has not fully matched performance!

Volatility is where the differences become more pronounced. Both funds are volatile, but GDXJ consistently exhibits higher volatility due to its exposure to smaller and less established companies.

Over the last five years, GDX experienced a maximum drawdown of 46.13%, while GDXJ fell 51.40%. More importantly, GDX’s drawdown lasted 855 days, compared with 1,234 days for GDXJ.

Over a longer horizon, from November 2009 through January 2026, both ETFs have underperformed spot gold. GDX delivered an annualized return of 5.11%, GDXJ returned 3.53%, while spot gold ETFs returned roughly 8.7%.

That gap highlights the downside of operational leverage during flat or declining gold cycles. Losses compound more quickly, and recovery requires larger subsequent gains.

Junior miners also face additional risks beyond price volatility. These include financing risk, project delays, reserve uncertainty, and geopolitical risk such as expropriation or unfavorable regulatory changes in resource-heavy regions.

Verdict: From a risk and return standpoint, GDX remains the more balanced option. It benefits from stronger balance sheets, better access to capital, and more diversified business models. GDXJ can amplify gains in strong bull markets for gold, but it also magnifies losses and drawdowns. For most investors, GDX is the easier entry point when expressing a bullish view on gold.
