Comparing SIL and GLDM: Which Precious Metals ETF Fits Your Investment Goals?

When evaluating precious metals investments, two popular ETFs—the SPDR Gold MiniShares Trust (GLDM) and the Global X - Silver Miners ETF (SIL)—offer distinctly different approaches. While both provide exposure to precious metals, their structures, fee profiles, and risk characteristics vary significantly. Understanding these differences can help investors determine which vehicle aligns with their financial objectives. The comparison breaks down to a simple ratio: for every unit of risk in GLDM, SIL carries considerably more volatility—roughly in the ballpark of 1.32 as a fraction when comparing their beta and volatility metrics.

Cost Structure: A Major Dividing Line

One of the most striking differences lies in expense ratios. GLDM charges just 0.10% annually, while SIL costs 0.65%—a meaningful gap for long-term investors. This six-fold difference accumulates over time, particularly for buy-and-hold strategies. GLDM’s lower fees reflect its simpler structure: it holds physical gold bullion directly, requiring minimal operational oversight. SIL, meanwhile, incurs higher costs managing a portfolio of silver mining companies.

Dividend considerations also differ. SIL offers a 1.18% dividend yield, generated from mining company earnings, while GLDM provides no dividend at all. For income-focused investors, SIL’s distribution advantage may partially offset its higher expense ratio. However, for total cost of ownership, GLDM remains the more economical choice.

Performance and Risk: A Contrasting Five-Year Story

The relationship between risk and reward becomes evident when examining historical data. Over the past five years, GLDM grew a $1,000 investment to $2,473, while SIL reached only $2,094—suggesting that despite higher volatility, SIL underperformed. Yet the past 12 months tell a different story: SIL delivered a 186.7% return versus GLDM’s 69.26%, capitalizing on a surge in silver prices.

The volatility gap, however, is substantial. GLDM’s maximum drawdown over five years was -21.63%, while SIL experienced a peak-to-trough decline of -56.79%—nearly three times worse. Beta measurements amplify this picture: GLDM’s beta of 0.51 indicates relatively modest price swings compared to the S&P 500, while SIL’s 0.90 beta demonstrates much tighter correlation with broader market movements and sector cycles.

Understanding the Structural Difference

The performance disparity stems from fundamental differences in what these funds hold. GLDM is a physically backed gold trust containing actual bullion, designed to track the metal’s spot price with minimal additional variables. This straightforward structure limits upside potential but also dampens downside risk.

SIL, by contrast, holds equity stakes in mining operations. Its top three holdings—Wheaton Precious Metals, Pan American Silver, and Coeur Mining—collectively represent over 40% of the fund. Investors buying SIL gain exposure not just to silver price movements but also to mining company profits, operational efficiency, production volumes, and sector dynamics. This leverage amplifies returns during strong commodity cycles but magnifies losses during downturns.

Evaluating Assets Under Management and Fund Scale

GLDM’s larger asset base of $25 billion provides greater liquidity and operational stability compared to SIL’s $5 billion in assets under management. The scale difference reflects broader investor preference for gold over silver, as well as GLDM’s cost advantage attracting capital. Larger fund sizes typically mean tighter bid-ask spreads and better execution for traders.

Which Fund Suits Your Needs?

Investors prioritizing stability and cost efficiency should lean toward GLDM. Its lower expense ratio, reduced volatility, and passive exposure to physical gold create a predictable, low-maintenance holding suitable for long-term portfolio building.

Those with higher risk tolerance and conviction about silver demand might prefer SIL. Recent performance demonstrates that mining equity leverage can generate substantial returns during favorable commodity environments. However, this approach demands emotional resilience—investors must tolerate drawdowns exceeding 50% historically.

Time horizon matters significantly. GLDM’s consistency makes it suitable for retirement accounts and multi-decade positions. SIL works better as a tactical allocation within portfolios where investors monitor sector fundamentals and remain comfortable with short-term volatility.

Key Takeaways

The choice between GLDM and SIL ultimately depends on balancing three factors: cost sensitivity, risk tolerance, and precious metals philosophy. GLDM offers low-cost, stable physical gold exposure through its streamlined structure. SIL provides leveraged silver exposure through mining companies, accepting higher fees and volatility for the potential of outsized returns. Understanding your investment timeline, fee impact, and comfort with drawdowns will guide the decision toward the vehicle that best serves your portfolio objectives.
