Gold-mining ETFs have drawn renewed attention as investors weigh persistent inflation concerns, central-bank gold buying, and geopolitical uncertainty against the headwind of higher-for-longer interest rates. The Themes Gold Miners ETF (AUMI) and the iShares MSCI Global Gold Miners ETF (RING) both offer concentrated access to the same broad theme, making them direct competitors in an ETF comparison. Yet the two funds are not identical: RING is an established, mega-cap-tilted vehicle with more than a decade of history, while AUMI is a younger, mid-cap-oriented offering. Understanding their structural differences in sector exposure, cost, and relative positioning is essential for investors choosing between them. I also checked this using Tickeron’s AI Screener to see how the funds compare on key metrics.
AUMI is a passively managed, non-diversified fund that tracks a rules-based index of the world's largest gold-mining companies by market capitalization. Launched in December 2023, it is considerably younger than its peer and holds roughly 31 positions, with the top 10 names representing approximately 46% of assets. The portfolio is overwhelmingly concentrated in the materials sector, and its geographic mix leans heavily toward Canadian and Australian producers.
Top holdings include IAG (IAMGOLD), OceanaGold, EQX (Equinox Gold), AU (AngloGold Ashanti), GFI (Gold Fields), and KGC (Kinross Gold). The fund charges an expense ratio of 0.45% and uses a replication strategy, though it may employ representative sampling when full replication is impractical. Its mid-cap tilt gives it greater exposure to smaller, higher-operating-leverage miners that can amplify both upside and downside in gold-price cycles.
RING is a passively managed, non-diversified ETF that seeks to track the MSCI ACWI Select Gold Miners IMI Index, a benchmark of developed- and emerging-market companies primarily engaged in gold mining. Launched in January 2012, it is one of the most established gold-miner funds, with assets exceeding $4 billion and roughly 43 to 46 holdings. The top 10 positions account for about 66% of the portfolio, reflecting a meaningful mega-cap bias.
Leading holdings include NEM (Newmont), AEM (Agnico Eagle Mines), GOLD (Barrick Gold), WPM (Wheaton Precious Metals), and AU (AngloGold Ashanti). RING's expense ratio is 0.39%, slightly below AUMI's. With roughly 99% of assets classified as gold-related and the remainder in diversified metals, the fund is effectively a pure-play expression of the sector, and its substantial scale supports tighter spreads and deeper liquidity.
The gold-mining sector sits at the intersection of several macro forces. Sustained central-bank purchases of physical gold and elevated geopolitical risk have supported bullion prices, while real interest-rate expectations continue to influence the opportunity cost of holding gold. Miners add a second layer of dynamics: energy and labor costs, mine-grade quality, currency effects, and capital-allocation discipline all shape earnings independently of the metal price. Regulatory and permitting developments in key jurisdictions such as Canada, Australia, and South Africa also matter. Both AUMI and RING are highly sensitive to these factors, and investors should expect above-average volatility relative to broad equity benchmarks given the funds' single-sector exposure.
In recent market cycles, both funds have participated in a strong gold-miner rally, though their relative positioning has produced different performance profiles. AUMI's greater weight in mid-cap producers has tended to amplify returns during risk-on stretches, as smaller miners offer higher operating leverage to rising gold prices. RING, by contrast, is anchored by large-cap producers and royalty companies, which generally exhibit steadier balance sheets and more diversified asset bases, contributing to a somewhat lower-volatility profile. Relative performance has therefore hinged on whether investors favored higher-beta smaller miners or the liquidity and scale of established leaders. Cost and structure favor RING over the long term, while AUMI's construction may offer a sharper tactical tilt during momentum-driven phases. From what I see, this distinction matters most when gold prices move sharply in either direction.
When comparing funds like AUMI and RING, I frequently rely on Tickeron’s AI Screener to quickly filter by sector exposure, expense ratios, and liquidity metrics. It surfaces relevant data in seconds and helps me cross-check structural differences without manual effort, which keeps my research process efficient and focused.
Based on observable structural factors, Tickeron's AI would likely favor RING over AUMI at present. RING combines a lower expense ratio, substantially deeper liquidity, a longer operating track record, and exposure to financially resilient mega-cap miners, all of which support more consistent relative positioning across market environments. While AUMI's mid-cap tilt has generated notable momentum during recent upswings, its higher cost, smaller asset base, and greater sensitivity to single-issuer outcomes introduce additional risk. On a probabilistic basis, RING's cost efficiency, scale, and diversification across established producers make it the more durable choice for investors seeking broad gold-miner exposure. I'm watching this closely as gold prices evolve.
