SPDR Gold Shares and Global X - Silver Miners ETF offer sharply different exposure, fees, and risk profiles-one tracks physical gold, the other invests in silver mining stocks. Here's how their returns, volatility, and costs stack up for U.S. investors
Precious metals have drawn renewed attention from investors seeking protection against inflation and market volatility, but not all metals funds are created equal. Two of the most prominent options-SPDR Gold Shares (GLD) and Global X - Silver Miners ETF (SIL)-offer fundamentally different approaches to the sector. Understanding how these funds differ in structure, cost, and risk is essential for anyone considering an allocation to gold or silver in their portfolio.
While both funds provide exposure to metals, GLD tracks the price of physical gold bullion, serving as a direct hedge against currency devaluation and market stress. In contrast, SIL invests in a basket of global silver mining companies, making it more sensitive to corporate performance, management decisions, and industrial demand for silver. This distinction shapes not only their returns but also their volatility and tax treatment.
Comparing Structure and Fees
SPDR Gold Shares is structured as a trust that holds physical gold bars in secure vaults, with shares representing fractional ownership of that gold. This design allows investors to gain exposure to gold's price movements without the logistical challenges of buying and storing bullion. GLD's expense ratio is 0.40%, making it one of the more cost-effective ways to access gold in ETF form.
Global X - Silver Miners ETF, on the other hand, holds equity stakes in 39 silver mining companies worldwide. Its portfolio is concentrated entirely in the basic materials sector, with top holdings such as Wheaton Precious Metals, Pan American Silver, and Coeur Mining accounting for a significant share of assets. SIL's expense ratio is higher at 0.65%, reflecting the additional management and research required to track a diversified group of mining stocks. Investors should also consider trading costs and liquidity, as these can affect total ownership expenses over time.
Volatility, Returns, and Risk
The risk and return profiles of these funds diverge sharply. Over the trailing 12 months ending July 23, 2026, SIL delivered a total return of 49.4%, outpacing GLD's 19.0%. However, this outperformance comes with greater volatility: SIL's five-year maximum drawdown reached 48.7%, compared to 26.4% for GLD. Beta, a measure of price sensitivity relative to the S&P 500, stands at 0.84 for SIL and just 0.17 for GLD, underscoring the higher risk of mining stocks versus physical gold.
Dividend yield is another differentiator. SIL paid out 1.3% over the past year, while GLD does not distribute dividends, as gold itself generates no income. Over longer periods, GLD has generally outperformed SIL on a risk-adjusted basis, with five- and ten-year annualized returns of 17.5% and 11.3%, respectively, compared to SIL's 14% and 7.6%. Yet in shorter windows, such as the past three years, SIL has occasionally led, reflecting the cyclical nature of mining equities and industrial demand for silver.
Tax Implications and Practical Considerations
For U.S. investors, tax treatment is a key consideration. Gains from GLD are taxed as collectibles, with a maximum federal rate of 28% if held for more than a year-higher than the long-term capital gains rate for stocks. SIL, as an equity ETF, is taxed at standard capital gains rates, which may be lower for many investors. Holding either fund in a tax-advantaged account such as an IRA can help mitigate these differences.
Liquidity and fund size also matter. As of July 23, 2026, GLD managed $134.6 billion in assets, making it the largest gold-backed ETF globally, while SIL's assets under management stood at $4.2 billion. Larger funds typically offer tighter bid-ask spreads and greater trading flexibility, which can be important for active investors or those making sizable trades.

Choosing the Right Precious Metals Fund
Deciding between GLD and SIL depends on an investor's objectives and risk tolerance. GLD offers a straightforward way to track gold prices and is often used as a portfolio hedge during periods of economic uncertainty or rising inflation. Its lower volatility and expense ratio make it appealing for those seeking stability and simplicity.
SIL, by contrast, is an indirect play on silver prices through mining stocks, which can benefit disproportionately when silver rises due to operational leverage. However, these stocks are also exposed to company-specific risks, management execution, and broader equity market swings. The fund's higher volatility and drawdowns mean it may not suit all investors, but it can offer greater upside in strong silver markets, especially when industrial demand is robust.
Both funds have benefited from the recent surge in precious metals, with gold more than doubling and silver nearly tripling since early 2025. Yet their long-term performance and risk profiles remain distinct, and neither is immune to sharp reversals if metals prices retreat or market sentiment shifts.
Precious metals ETFs illustrate the trade-offs between direct commodity exposure and equity-based strategies. Physical gold funds like GLD provide a classic inflation hedge and store of value, but lack income and may face higher tax rates. Mining ETFs such as SIL can offer dividends and the potential for management-driven returns, but introduce additional layers of risk tied to corporate performance and the broader stock market. Investors should weigh these factors carefully, considering their own time horizon, tax situation, and appetite for volatility before choosing a fund.
