GDX vs. SLVP: Gold or Silver -- Which Mining ETF Is the Better Buy for Investors?

The iShares MSCI Global Silver and Metals Miners ETF (NYSEMKT:SLVP) and VanEck Gold Miners ETF (NYSEMKT:GDX) both track global mining, but SLVP leans toward silver exposure, while GDX is a much larger gold-focused heavyweight.

This comparison looks at key differences in cost, performance, risk, and portfolio makeup to help investors decide which may better suit their objectives.

Snapshot (cost & size)

Beta measures price volatility relative to the S&P 500; beta is calculated from five-year monthly returns. The 1-year return represents total return over the trailing 12 months.

SLVP has a lower expense ratio and also offers a higher dividend yield. GDX has a lower beta, meaning that its price swings tend to be less volatile than SLVP’s.

Performance & risk comparison

What's inside

GDX holds 57 stocks and exclusively targets companies involved in gold mining, tracking the MarketVector Global Gold Miners Index. Its largest positions are Agnico Eagle Mines (TSX:AEM), Newmont Corp. (NYSE:NEM), and Barrick Mining (TSX:ABX). As the largest ETF in its category, GDX provides 100% focused access to global gold miners and boasts substantial assets under management.

SLVP, by contrast, is tilted toward silver miners, with 36 holdings. The fund provides “exposure to companies that derive the majority of their revenues from silver exploration or metals mining.” Its top three holdings are Hecla Mining (NYSE:HL), Fresnillo (LSE:FRES), and Industrias Penoles (OTC:IPOAF) -- which together make up more than 34% of the portfolio. With its smaller number of holdings, investors in SLVP investors will see a larger number of more concentrated bets on silver companies, whereas GDX spreads its exposure among a broader set of gold producers.

What this means for investors

For retail investors trying to add precious metals exposure to a portfolio, the choice between GDX and SLVP isn't just about gold versus silver -- it's also a question of how much risk and concentration you're comfortable with.

Gold has historically been viewed as a safe-haven asset, and GDX is one of the most accessible ways to own a slice of the global gold mining industry. For investors who prioritize relative stability and a well-established track record, GDX is the more straightforward choice.

SLVP, on the other hand, is a smaller and more volatile fund. Silver tends to behave differently than gold -- it has industrial applications in electronics and clean energy technology that can amplify its price swings in ways that gold doesn't experience. That dual demand dynamic has helped SLVP outperform GDX over the past year, but it can also cut the other way when industrial activity slows.

With precious metals having attracted fresh attention amid ongoing macroeconomic uncertainty and a weaker U.S. dollar, both ETFs may appeal to investors looking to diversify beyond equities. But investors should be clear about what they're getting: GDX offers scale and stability in the gold mining space, while SLVP is a more aggressive, higher-yielding bet tied closely to the silver market's unique supply-and-demand dynamics.

Before diving in, though, a word of caution is warranted. Precious metals and mining stocks have had a remarkable run over the past couple of years, and strong recent performance is one of the most common ways investors talk themselves into taking on more risk than they intended. Mining ETFs like these are not low-drama investments -- they can drop 30%, 40%, or more in a downturn, and they've done exactly that before. The gains that look so compelling in a rear-view mirror have a way of reversing quickly when sentiment shifts.

Bottom line: these ETFs are specialized vehicles, and for most investors who want this type of exposure, they belong as a small, deliberate slice of a broader, diversified portfolio rather than a core holding. There is nothing wrong with keeping the bulk of your money in a plain, low-cost index fund that tracks the broad market -- something like a total market or S&P 500 ETF -- and treating a position in miners as a modest tactical allocation, if it fits your strategy at all. If you do invest in either of these funds, go in with both eyes open: size your position in a way that won't keep you up at night, and be mentally prepared for sharp moves in either direction.
