Overview
IAUI and SPYI are both monthly-distribution ETFs using covered-call strategies to generate high income, but they invest in fundamentally different assets. Both aim for tax efficiency through their options structure, but the underlying risk profile—commodity exposure versus large-cap equities—sets them apart.
How they differ
The core distinction is asset class: IAUI holds physical gold through ETPs, exposing investors to precious-metals price moves and inflation hedging; SPYI tracks the S&P 500, capturing broad U.S. large-cap equity growth. This matters because gold and equities respond differently to economic cycles and inflation signals.
Both funds use covered calls to generate their outsized yields, but their fee structures slightly favor SPYI at 0.68% versus 0.79%. SPYI's $11.7B AUM far exceeds IAUI's $600M, suggesting deeper liquidity and a longer operational history to build investor confidence. SPYI has been operating since 08/29/2022, while IAUI launched 06/05/2025, meaning SPYI's distribution record spans a full market cycle and the recent rate-hiking era, whereas IAUI has limited history to evaluate.
Who each is best for
- IAUI: Fits investors seeking an inflation hedge within a high-income sleeve who believe gold valuations will hold or rise and are comfortable with monthly cash flow from a commodity-focused, narrowly concentrated holding.
- SPYI: Designed for income-focused investors who want broad U.S. equity exposure alongside regular distributions and accept the tradeoff that high covered-call yields often come paired with capped capital appreciation.
Key risks to know
- NAV erosion at >12% yields. Both funds distribute more than 1% monthly. When the underlying assets (gold or equities) don't appreciate enough to offset distributions, NAV declines over time. This is especially acute in flat or down markets and compounds over years.
- Call-writing caps upside. Covered calls cap gains if underlying holdings rally sharply. SPYI investors forgo S&P 500 upside beyond the strike; IAUI holders miss gold spikes. The trade-off is intentional but meaningful over a multi-year horizon.
- Gold volatility and macro sensitivity. IAUI depends on gold's price action, which swings with real interest rates, USD strength, and geopolitical risk. Prolonged high real rates have historically pressured gold; rising rates could reduce both capital appreciation and the incentive to hold it.
- Options and derivative rollover risk. Both funds actively roll covered calls each month. Sharp market gaps, liquidity drying up, or mistimed rolls can force unfavorable prices or leave the fund briefly unhedged, adding tracking error and drag relative to simple buy-and-hold. While SPYI is diversified by count, both concentrate exposure relative to a broader market portfolio.
Bottom line
If you value inflation protection and believe gold will appreciate alongside income, IAUI offers a focused bet with a newer track record; if you prioritize established equity exposure, comparable yield, and deeper liquidity supported by a longer operating history, SPYI presents a different foundation. Both funds' high distribution rates assume call-writing discipline and stable underlying prices; neither should anchor a portfolio with low volatility tolerance.
