MSTY vs TSLY: Which Is the Better Pick in 2026?

Overview

MSTY and TSLY are both YieldMax covered-call ETFs that sell weekly options on a single underlying stock to generate income. MSTY targets MicroStrategy (MSTR), a Bitcoin-holding company with high volatility, while TSLY targets Tesla (TSLA), the electric-vehicle manufacturer. The critical difference: MSTY distributes 81.47% annually versus TSLY's 53.07%, a gap driven by MSTR's greater price swings and the outsized premiums available from writing calls on it.

How they differ

The biggest distinction is yield magnitude and volatility exposure. MSTY's 81.47% distribution rate reflects MSTR's roughly 2.56 beta versus TSLY's 1.50 beta—MSTR moves harder, so call premiums are richer. Both charge similar expense ratios (0.99% and 1.01%), but MSTY's $1.01B AUM suggests faster growth and tighter tracking than TSLY's $823M. Structurally, both run the same covered-call playbook: sell weekly calls on the underlying, keep the premium and dividends, and cap upside when shares are called away. The real difference is which horse you're riding—a crypto-adjacent treasury company versus a mature EV automaker—and how much volatility you're willing to harvest.

Who each is best for

MSTY: Fits investors who want to monetize extreme volatility and can tolerate a 2.56-beta equity exposure in exchange for outsized option premiums; suits tactical income seekers with a short time horizon and high conviction that MSTR will trade sideways to modestly higher over weeks to months.

TSLY: Fits investors seeking moderately elevated income (53% annualized) on a large-cap mega-cap technology holding without explosive volatility drag; suits longer-term allocators who view Tesla as a core position and see the covered call as a way to boost yield without abandoning the underlying.

Key risks to know

• NAV erosion at extreme distribution yields. MSTY's 81% distribution rate means the fund is returning capital on a scale that typically forces steady share-price decline even if the underlying appreciates modestly. Over a full year, this math invites significant dilution unless MSTR returns outpace distributions—a high bar.

• Single-stock concentration and call-assignment risk. Both funds hold one equity. If MSTR or TSLA rallies sharply, covered calls cap gains and shares may be called away, forcing reinvestment at higher prices. Conversely, if the stock crashes, the call premium provides limited downside cushion.

• Crypto-proxy risk specific to MSTY. MicroStrategy is a leveraged Bitcoin proxy—it holds BTC on a balance sheet funded partly by debt. A sharp Bitcoin drawdown or a credit event at MSTR creates dual-layer losses that pure equity or broader crypto exposure wouldn't face.

• Options-market liquidity and roll risk. Weekly call-writing depends on consistent bid-ask spreads and open interest. Periods of low implied volatility or market stress can narrow premiums and force the fund to hold stock longer than intended, delaying income capture.

• High beta amplifies both rallies and drawdowns. MSTY's 2.56 beta means a 10% market decline becomes a 25%+ fund decline before call protection kicks in. TSLY's 1.50 beta is lower but still material for equity-market selloffs.

Bottom line

If you want maximum income from a high-volatility equity and can tolerate weekly rebalancing and NAV drift, MSTY's 81% yield reflects the real optionality embedded in MicroStrategy's moves. If you prefer a smoother ride with meaningful (though lower) income on a household-name holding, TSLY's 53% yield and 1.50 beta offer steadier execution. Both are options plays, not buy-and-hold equity positions; past performance of the underlying stock, implied volatility, and call premiums will shift the income profile quarter to quarter.
