IAU vs. AAAU: Which Physical Gold ETF Is the Better Buy for Investors?

Gold-backed ETFs AAAU and IAU delivered nearly identical exposure, with trailing one-year returns of 14.4% and 14.2%, respectively, and five-year maximum drawdowns of about 26.3%. AAAU offers the lower 0.18% expense ratio versus IAU's 0.25%, while IAU provides substantially greater scale and likely liquidity with $67.5 billion in AUM versus AAAU's $2.9 billion. The comparison suggests AAAU is modestly more cost-efficient for long-term holders, whereas IAU is the more established and liquid vehicle.

Analysis

This is not a directional gold signal; it is a marginal product-selection issue. The annual 7bp fee advantage in AAAU only becomes economically meaningful for long-duration, low-turnover allocations, while IAU's substantially deeper secondary-market liquidity is likely worth more than the fee difference for institutional hedges, tactical books, or any mandate requiring rapid creation/redemption capacity. The practical implication is that large reallocations should continue to concentrate in IAU (and, by extension, GLD), limiting the likelihood that AAAU's lower fee alone drives material share capture.

The relevant second-order exposure is GS, whose ETF franchise gains modestly if AAAU attracts advisory-platform assets, but the revenue pool is immaterial relative to group earnings and does not alter the GS thesis. More important, fee competition in physically backed commodity ETFs can pressure industry economics if iShares responds; BlackRock's broader ETF fee realization, rather than GS's earnings, would be the cleaner fundamental sensitivity. No evidence here supports a gold-price forecast, inflation trade, or a read-through to NFLX or NVDA.

Over 1-3 months, monitor AAAU net creations relative to IAU, bid/ask spreads during volatile gold sessions, and securities-lending/creation costs rather than headline AUM. A sustained flow shift would require distribution adoption by RIAs or platforms, not retail recognition of a small fee differential. The thesis that IAU retains institutional primacy is falsified if AAAU's daily dollar volume and net inflows rise persistently enough to narrow its liquidity disadvantage without elevated spreads.

Key Decisions for Investors

• No directional trade in GS, NFLX, or NVDA: the disclosed comparison has no material earnings or demand read-through for these equities.
• For strategic gold allocations with a 12+ month horizon and modest sizing, use AAAU as the lower-carry physical-gold vehicle; the expected advantage is approximately 7bp per year before trading costs.
• For tactical gold hedges, options overlays, or block execution over days to 3 months, retain IAU (or GLD) unless AAAU demonstrates consistently comparable dollar volume and quoted spreads; execution slippage can readily exceed years of fee savings.
• Set a watch alert rather than a trade: reassess ETF-franchise fee-pressure risk if AAAU receives major wirehouse/RIA platform inclusion and posts sustained relative net inflows for two consecutive quarters.
