Overview
MSTY and YMAX are both weekly-paying covered-call ETFs from YieldMax, but they target entirely different underlying exposures. MSTY writes calls on a single stock—MicroStrategy (MSTR), a leveraged Bitcoin proxy—while YMAX is a fund-of-funds that holds a basket of YieldMax's own single-stock option-income ETFs across different companies. The key distinction: MSTY offers concentrated, high-volatility call income on one crypto-linked play; YMAX provides diversified call income across multiple holdings and sectors.
How they differ
MSTY's 83.49% distribution yield comes from weekly call premiums on MSTR, which carries a beta of 2.5604 and tracks the volatile Bitcoin-proxy market. YMAX's 46.62% yield is spread across a diversified portfolio of similar covered-call strategies on different single stocks, with a substantially lower beta of 1.5515. The most significant consequence: MSTY's narrower focus means its NAV can swing sharply when MSTR rallies past short-call strike prices or crashes below them, whereas YMAX's diversification smooths those single-position swings. MSTY's 0.99% expense ratio is cheaper than YMAX's 1.28%, but YMAX's higher fee partly reflects fund-of-funds administration and diversification overhead. MSTY has accumulated $1.01 billion in AUM since February 2024, while YMAX has built $420 million since January 2024.
Who each is best for
MSTY: Fits investors with a strong directional view of Bitcoin or MicroStrategy who want leveraged call premium income from that bet, and who can tolerate sharp NAV swings when MSTR makes large moves in either direction.
YMAX: Designed for investors seeking steady, diversified call-income streams across multiple single-stock option strategies, with preference for lower volatility and broader sector exposure than a single concentrated play can offer.
Key risks to know
- Extreme volatility and NAV erosion at MSTY's yield level. An 83.49% annualized distribution yield on a single stock with a beta over 2.5 signals that call premiums are being captured in full, leaving little room for appreciation. If MSTR rallies sharply, calls are exercised and the position resets; if it falls, NAV erodes faster than the high yield can offset. This dynamic is built into covered-call structures on volatile underlyings and will persist.
- Concentration risk in MSTY. Holding only MSTR means all portfolio risk is on one security's corporate, regulatory, and market-linked factors. A single adverse event—regulatory action against MicroStrategy or Bitcoin, competitive pressure, or margin call issues—creates single-point-of-failure risk that diversification cannot reduce.
- Fund-of-funds complexity in YMAX. YMAX holds other YieldMax ETFs, which themselves hold single stocks and execute call strategies. Fees nest (YMAX's 1.28% sits atop the expense ratios of its underlying holdings), and performance depends partly on the quality and stability of YieldMax's other strategy implementations.
- Call-capped upside in both. Covered-call structures cap the participation in sharp rallies. If MSTR or YMAX's underlying holdings surge past strike prices, shares are called away or gains are foregone—a trade-off baked into the weekly premium income but important to weigh against buy-and-hold potential.
- Cryptocurrency and single-stock volatility in MSTY. MSTR's price moves are leveraged to Bitcoin sentiment and corporate leverage; volatility in that pair can amplify losses during sharp drawdowns, compressing NAV even as distributions continue.
Bottom line
MSTY pursues maximum call income on a single leveraged position, accepting extreme volatility and NAV erosion risk in exchange for an 83.49% yield; YMAX trades that concentration for a lower 46.62% yield spread across multiple holdings and much lower beta, adding a layer of diversification and stability. If you crave a focused, high-income bet on Bitcoin via MSTR and can tolerate weekly NAV swings, MSTY's concentrated yield stands out; if you want steady covered-call income with less concentration risk, YMAX's diversified approach addresses that differently.
