Overview
MSTY and TSLY are both YieldMax covered-call ETFs that sell weekly call options on a single underlying stock to generate income—MSTY on Microstrategy (MSTR), TSLY on Tesla (TSLA). Both use the same options-overlay structure and weekly distribution frequency, but they differ significantly in yield, underlying volatility, and the leverage profile of their base holdings.
How they differ
The most obvious gap is yield: MSTY distributes at 83.49% annualized versus TSLY's 52.72%, a difference driven by MSTR's extreme volatility and the deeper out-of-the-money call strikes YieldMax can sell against it. MSTR's beta of 2.56 versus TSLA's 1.43 reflects that volatility—Microstrategy is a leveraged bet on Bitcoin held by a public company, making it structurally more volatile than Tesla's business. That high beta and elevated yield in MSTY raise the odds of call assignment or NAV pressure if MSTR rallies sharply. TSLY has been running longer (since November 2022 versus February 2024), giving it a longer track record, though both carry similar 0.99–1.01% expense ratios and rely on options premium that can evaporate in calm markets.
Who each is best for
MSTY: Fits investors seeking maximum current income from a volatile single-stock holding and comfortable with the risk of call assignment, dividend capture that may reverse if MSTR corrects sharply, and the possibility of NAV erosion if the underlying rallies past strike levels.
TSLY: Designed for investors who want weekly income from Tesla exposure but with a moderately lower yield and significantly lower volatility drag—suitable for those valuing capital stability alongside distributions and willing to accept call capping on a mega-cap growth stock.
Key risks to know
- Call assignment and cap risk. Both funds aim to be called away on every expiration cycle; if MSTR or TSLA underperforms or drifts lower, the call expires worthless and the next week's premium may shrink. Neither fund will deliver upside if the underlying surges past the call strike.
- NAV erosion at extreme yields. MSTY's 83.49% annualized distribution rate means shareholders are harvesting far more than the underlying MSTR is likely to generate in total return. That gap nearly always requires return-of-capital distributions, which erode per-share NAV over time even if the stock itself holds flat or rises modestly.
- Volatility collapse and premium compression. Covered-call income depends on implied volatility (IV) in options markets. If MSTR's or TSLA's IV contracts—a common risk in risk-off environments—weekly premium drops sharply, and distributions will fall alongside it.
- Single-stock concentration. MSTY holds only Microstrategy, a leveraged play on Bitcoin sentiment through a single company, amplifying idiosyncratic and macro crypto risk. TSLY holds only Tesla, tying all capital to one automaker's execution and EV cycle risks.
- Leverage embedded in MSTR. Microstrategy finances Bitcoin purchases with debt; a sharp decline in Bitcoin or tightening of credit conditions could force asset sales and pressure the stock, compounding the downside from call assignment.
Bottom line
MSTY appeals to income hunters willing to chase the yield premium of a highly volatile, leveraged-proxy underlying; TSLY offers a moderate, weekly income stream backed by a more predictable mega-cap holding. The key tradeoff is sustainability: MSTY's 83% yield is mathematically hard to sustain without NAV decay, while TSLY's 53% is closer to plausible long-run premium capture. Past performance, especially the strong recent rally in both MSTR and TSLA, does not predict future option premium or distribution sustainability.
