Overview
IAUI and SPYI are both monthly-distribution ETFs managed by NEOS using covered-call overlays to generate high income, but they target fundamentally different underlying assets. The choice between them hinges on asset class conviction: precious metals diversification versus broad U.S. equity exposure.
How they differ
The largest distinction is the underlying asset class. This shapes both their income mechanics and portfolio role fundamentally.
IAUI's yield of 12.47% exceeds SPYI's 11.95% by 0.52% percentage points. SPYI, backed by $12.4B in assets versus IAUI's $626M, has a longer track record (inception 08/29/2022 versus 06/05/2025) and lower expense ratio at 0.68% versus 0.79%.
Concentration and volatility risks differ sharply. Gold price swings can drive NAV moves independent of equity markets; S&P 500 moves track broader economic conditions. Both use options overlays, but IAUI's precious-metals focus introduces commodity-specific tail risk, while SPYI's large-cap equity base offers more traditional stock-market drawdown exposure.
Who each is best for
IAUI: Fits investors seeking a tactical metals allocation with monthly income who believe gold offers portfolio diversification and can tolerate higher single-asset volatility and concentration in exchange for yield above equity-market highs.
SPYI: Designed for investors wanting S&P 500 exposure with a high monthly payout who prioritize liquidity and size, accept lower yield in exchange for broad market participation and a longer operational history.
Key risks to know
- NAV erosion at extreme yields. IAUI's 12.47% distribution rate and SPYI's 11.95% both exceed typical underlying-asset returns by wide margins. Distributions at these levels suggest reliance on return of capital, which may erode net asset value over extended holding periods.
- Covered-call friction. Both funds sell calls to fund distributions, capping upside gains if the underlying assets rally significantly. This drag accumulates during bull markets and may underperform a buy-and-hold equivalent.
- Tax-efficiency limits. While both claim tax-efficient treatment, monthly distributions with high yields typically generate substantial taxable events. The stated tax efficiency likely reflects options-overlay technique rather than absolute tax minimization.
- Options-derivative basis risk. Both funds' call-selling strategies rely on implied-volatility pricing and counterparty execution. Rapid volatility shifts or market dislocations could degrade the relationship between the fund's underlying and its synthetic-income layer.
Bottom line
If you're seeking broad U.S. stock exposure with monthly income, SPYI's larger asset base and lower expense ratio merit attention; if you want precious-metals diversification at a steeper yield, IAUI addresses a different portfolio role. Past performance does not guarantee future results.
