Gold miners offer leveraged exposure to gold. Operating leverage can amplify profits during gold bull markets.
-
Higher returns come with higher risk. GDX and especially GDXJ are much more volatile and prone to deep declines than GLD.
-
Long-term capitalization favors stability. Despite excellent recent performance, GLD has generated stronger long-term returns due to lower volatility.

The degradation business has produced quite a few winners. One of the most obvious is the SPDR Gold Stock ETF (NYSEMKT: GLD). As of mid-March 2026, the fund surpassed a whopping $180 billion in assets under management, driven in part by roughly $15 billion in net inflows in the first quarter alone.
Confidence in the US dollar has been fading. Persistent deficits, high interest rate volatility, and ongoing monetary expansion have contributed to concerns about long-term purchasing power. At the same time, geopolitical tensions have continued to rise. The war between Russia and Ukraine, the conflict between Israel and Hamas and rising tensions involving the United States and Iran have reinforced demand for perceived safe haven assets.
Gold is at the center of that trade. In 2026, gold prices surpassed $5,000 per ounce and held those levels for much of March before retreating toward $4,500. As expected, it has been a strong environment for gold-backed ETFs. As of February 28, 2026, GLD has returned 83.53% over the last one-year period based on net asset value.
But it wasn’t really the best way to play gold. During that same period, gold mining ETFs generated significantly higher returns. He VanEck Gold Miners ETF (NYSEMKT: GDX) returned 192.31%, while the most speculative VanEck Junior Gold Miners ETF (NYSEMKT: GDXJ) rose 225.3%.
That’s a big difference. But before we rush to chase those higher returns, there are important nuances we need to understand. The same factors that amplified mining stock gains can easily work in reverse. Here’s what you need to know.
The first thing to understand is that these are fundamentally different products.
GLD owns physical gold bars. It sits in a vault and each share represents fractional ownership of that gold. Your returns depend almost entirely on the spot price of gold, minus fees.
GDX and GDXJ, on the other hand, do not contain gold at all. They own shares of companies that explore, extract and sell gold. That distinction changes everything.
With GLD, its performance closely follows the price of gold. With GDX and GDXJ, returns depend on both gold prices and how well these companies operate. That includes how efficiently they find reserves, how cheaply they can extract them, and how profitably they can sell their production.
This is where a key concept comes into play: all-inclusive sustained cost or AISC. AISC measures the total cost required to produce one ounce of gold, including operating expenses, sustaining capital, and overhead. It is essentially the break-even level for a mining company.
If a miner has an AISC of $1,500 per ounce and gold is trading at $2,000, he makes a margin of $500. If gold rises to $2,500, that margin doubles to $1,000. The price of gold only increased by 25%, but profits increased by 100%. That’s operating leverage.
During a strong gold bull market, that leverage can lead to outsized gains for mining stocks. Higher margins drive earnings growth, which translates into higher earnings per share and, ultimately, higher stock prices.
But the same dynamic works in reverse. When gold prices fall, margins compress quickly. Profits can disappear completely and stock prices tend to fall much more than gold itself.
This is why you will notice different levels of “twist” between these ETFs. GDX amplifies gold price movements more than GLD, but GDXJ goes even further. The reason comes down to what each fund has.
GDX focuses on larger, more established mining companies. GDXJ, on the other hand, owns smaller “young” miners. These companies are typically still in the exploration phase, may not yet be profitable, and often rely on issuing new shares to finance their operations. That makes them higher risk and higher reward.
Over short periods, especially during a gold bull market, it is easy to assume that if GLD is doing well, GDX and GDXJ must be even better. But a longer-term perspective tells a different story.
According to testfolio.io, over a period of 16.36 years from November 2009 to March 2026, GLD earned an annualized return of 8.3%. GDX lagged with 4.17%, while GDXJ performed even worse with just 2.62%.
Gold and gold miners go through periods of boom and bust. During recessions, mining stocks can experience deep declines, and the math of capitalization works against them. A 10% loss requires an 11% gain to recover from, and the deeper the loss, the harder it is to come back from.
Mining ETFs have had to dig much deeper holes. At its worst, GLD fell by approximately 19.62%. GDX fell 45.84% and GDXJ fell as much as 61.56%. That level of volatility makes long-term compounding much more difficult.
This does not mean that GDX or GDXJ are bad investments. But they are cyclical and high-volatility tools that require careful evaluation of positions and an understanding of the broader gold cycle. If you’re looking for leveraged exposure to gold, they may make sense. Simply recognize the trade-offs.
You might think retirement is about picking the best stocks or ETFs and saving as much as possible, but you’d be wrong. After the release of a new report on retirement income, wealthy Americans are reconsidering their plans and realizing that even modest portfolios can become major ATMs.
Many are even learning that they can retire earlier than expected.
