AAAU vs IAUM

Key Takeaways

• Both AAAU and IAUM are physically backed gold ETFs that track the LBMA (London Bullion Market Association) Gold Price, offering direct bullion exposure without derivatives.
• IAUM carries a lower fee — 0.09% gross (0.07% net after waiver) versus AAAU's 0.18% — a structural cost advantage that compounds for long-term holders.
• Both funds are grantor trusts holding a single asset (allocated gold bullion), so neither provides equity diversification or dividend income.
• IAUM commands greater scale with roughly twice the assets under management, while AAAU offers a longer operating history (2018 versus 2021).
• Tickeron AI Verdict: IAUM is favored for its identical exposure delivered at a meaningfully lower cost and with superior liquidity scale.

Introduction

Gold has re-emerged as a focal point for investors navigating persistent inflation concerns, currency debasement, and geopolitical uncertainty. Within this environment, choosing the right vehicle matters, because two funds can track the same metal yet differ sharply in cost and structure. The Goldman Sachs Physical Gold ETF (AAAU) and the iShares Gold Trust Micro (IAUM) are direct competitors in the physically backed gold ETF category. Both pursue the same objective — tracking the spot price of gold — which makes this a useful ETF comparison focused on structural efficiency, cost, and liquidity rather than divergent strategies.

Goldman Sachs Physical Gold ETF (AAAU) Overview

AAAU is a passive, physically backed exchange-traded fund structured as a grantor trust. Its investment objective is to reflect the performance of the price of gold, less the trust's expenses, using gold bars that meet London Good Delivery standards and are held in secure vaults in the United Kingdom. The fund does not use futures, swaps, or other synthetic instruments.

Structurally, the fund effectively holds a single asset: 100% allocated physical gold bullion. It has no meaningful sector allocation beyond precious metals and carries no equity or fixed-income exposure. The trust's custodian is JPMorgan Chase Bank, N.A., and shares represent a fractional undivided beneficial interest in the trust's net assets.

Launched in July 2018, AAAU charges an expense ratio of 0.18% and holds on the order of $3 billion in assets under management (AUM, the total market value of the fund's holdings). Because gold generates no cash flow, the fund pays no distributions; the share count of gold represented declines gradually as gold is sold to cover the sponsor's fee and operating expenses.

iShares Gold Trust Micro (IAUM) Overview

IAUM is BlackRock's low-cost entry into the physical gold ETF market. Like AAAU, it is a passive grantor trust whose objective is to reflect generally the performance of the price of gold. The trust's assets consist primarily of physical gold held by a custodian on behalf of the trust, stored in secure, segregated, allocated form, including fractional bars.

The fund is benchmarked to the LBMA Gold Price and holds essentially a single position — physical gold bullion — with no equity, bond, or derivative exposure. It was launched in June 2021 and has grown to roughly $7 billion in AUM, making it one of the larger and more liquid vehicles in the physically backed gold segment.

IAUM's defining characteristic is cost. It carries a gross sponsor fee of 0.09%, with a voluntary waiver reducing the net fee to approximately 0.07% through June 30, 2027. This positions IAUM among the lowest-cost gold exchange-traded products on the market, an important consideration where identical underlying exposure makes fee differentials the primary driver of relative returns over time.

Industry and Thematic Backdrop

Both funds operate in the precious metals commodity segment, where the dominant theme is demand for gold as a store of value and inflation hedge. Recent market cycles have been shaped by elevated central-bank gold purchases, expectations around real interest rates, U.S. dollar strength or weakness, and geopolitical tension. Because gold typically offers no yield, its opportunity cost rises when real interest rates climb and falls when they decline, making monetary-policy expectations a key driver of fund performance.

Regulatory and structural considerations also matter. Physically backed gold ETFs organized as grantor trusts are not registered investment companies under the Investment Company Act of 1940 and are not commodity pools under the Commodity Exchange Act. This structure is designed to give shareholders direct, undivided ownership of allocated bullion, which influences tax treatment and custody mechanics relative to synthetic or futures-based products.

Performance and Positioning Comparison

Because AAAU and IAUM track the same benchmark, their gross performance profiles are nearly identical over recent weeks and months. Relative positioning is therefore driven less by return dispersion and more by cost efficiency, tracking precision, and liquidity. Over the trailing one- and three-year periods, both funds have delivered comparable NAV (net asset value) returns that closely mirror the LBMA Gold Price.

The practical distinction is the fee drag. A 0.18% expense ratio versus a net 0.07% fee may appear minor in any single year, but it compounds meaningfully over multi-year holding periods. IAUM's larger AUM and average trading volume also support tighter bid-ask spreads and efficient execution, while AAAU's longer history offers investors a more extended observable track record. Volatility in both funds is essentially equivalent, reflecting the same underlying bullion exposure rather than any divergence in strategy or portfolio construction.

Tickeron AI Verdict

Based on observable structural factors, Tickeron's AI would likely favor IAUM in this pairing. Both funds deliver functionally identical gold exposure, which shifts the decision toward cost efficiency, scale, and liquidity. IAUM's net fee of roughly 0.07% is less than half of AAAU's 0.18%, and its larger asset base supports efficient trading and tighter spreads. While AAAU's longer track record is a legitimate consideration, the combination of lower cost, superior scale, and identical benchmark tracking gives IAUM the probabilistic edge for most long-term holders. This assessment reflects relative structural efficiency and is not a personalized recommendation.
