Overview
MST and MSTY are both ETFs that harvest income from MicroStrategy (MSTR) using options strategies rather than owning shares directly. MST uses leveraged long exposure paired with swap agreements to amplify upside and generate weekly income; MSTY uses a covered-call approach that caps gains in exchange for high current yield. Both track the same underlying company but with fundamentally different risk-return mechanics and payout structures.
How they differ
The biggest difference is leverage versus upside cap. MST applies 5.1684 beta exposure to MSTR through leverage and derivatives, betting that the stock will rise and funding income along the way; MSTY uses covered calls, which means it sells away gains above a strike price in return for 92.95% yield. MST's 1.91% expense ratio is higher than MSTY's 1.03%, and MSTY has $1.14B in assets versus MST's $26.7M—a 43-fold difference in size. Both rebalance weekly, but MSTY's larger asset base and lower fees reflect a more established strategy that has been running since 02/21/2024, while MST launched 05/01/2025.
Who each is best for
MST: Fits investors with high risk tolerance who believe MSTR will appreciate meaningfully and are willing to endure leveraged swings in exchange for current income and upside participation. Works for short time horizons and active monitoring.
MSTY: Fits investors who prioritize income consistency and are indifferent to or expect modest appreciation in MSTR, preferring to trade away upside beyond call strike levels. Suits longer holding periods and more passive income-focused allocation.
Key risks to know
- NAV erosion at extreme distribution yields. MSTY's 92.95% annualized distribution rate, if paid entirely from realized gains and income (which is unlikely), would require MSTR to deliver outsized returns to sustain the distribution without eroding NAV over time.
- Leverage and volatility amplification in MST. MST's 5.1684 beta means a 10% move in MSTR produces a roughly 51% swing in MST value. Swap agreements and leveraged derivatives can amplify losses if MSTR declines sharply, and the strategy's reliance on refinancing or rolling swaps introduces counterparty and funding-cost risk during market stress.
- Capped upside in MSTY. MSTY's covered-call structure means gains in MSTR above the call strike are transferred to option writers, not retained by shareholders. If MSTR experiences a sustained rally, MSTY will trail the underlying stock materially.
- Single-stock concentration and volatility. Both funds hold only MSTR exposure, which is a highly volatile asset tied to MicroStrategy's Bitcoin holdings and business strategy. A deterioration in either the company's core business or cryptocurrency markets will hit both equally hard.
- Options and synthetic-income risk. Both strategies rely on derivatives that require active management, roll-over execution, and favorable pricing. If option markets become illiquid or implied volatility collapses, funding for distributions may become constrained and NAV per share may adjust downward.
Bottom line
If you want leveraged upside and can tolerate 5.1684 beta swings, MST offers that trade at a higher cost; if you prioritize maximum current yield and accept that gains above strike prices will be forfeited, MSTY's larger asset base and lower fees suggest a more established market presence. Both are derivative-heavy single-stock bets on MSTR, so concentration and options risk are unavoidable—verify option liquidity, monitor distribution composition, and treat both as tactical allocations, not core holdings. Past performance doesn't guarantee future results, and yields this high depend critically on options pricing and MSTR volatility remaining supportive.
