MSTY vs ULTY: One Stock's Options, or an Ultra Basket?

Overview

Both MSTY and ULTY are weekly-paying option-income ETFs from YieldMax that use covered calls to generate yield, but they're fundamentally different in structure. MSTY is a single-stock play—it holds MicroStrategy (MSTR) and sells call options against it, capping your upside but letting you keep downside exposure. ULTY diversifies across a rotating basket of high-volatility U.S. stocks and layers in synthetic calls for enhanced income. The key distinction is concentration versus diversification, paired with dramatically different yield targets.

How they differ

The biggest difference is scope: MSTY tracks one company (MicroStrategy, a software and crypto-adjacent holding), while ULTY rotates through a basket of volatile stocks. That concentration gives MSTY a beta of 2.5604, more than double ULTY's 1.3581, meaning MSTY will swing harder in either direction.

Income is the second major divergence. MSTY targets a 98.88% distribution rate versus ULTY's 59.55%, a gap driven partly by MSTR's own volatility and partly by MSTY's design—the higher yield is the trade-off for capping your capital appreciation on MicroStrategy shares. ULTY's lower yield pairs with diversification and a brake on downside through its hedging strategy.

Fees and AUM underscore the scale difference. MSTY charges 1.03% and holds $1.13B in assets; ULTY costs 1.40% and manages $721M. Both funds are young—MSTY launched 2 years, ULTY 2 years—so neither has a long track record.

Who each is best for

• MSTY: Investors who want high current income from a crypto-adjacent equity holding and accept that their gains in MicroStrategy will be capped in exchange for weekly payouts and downside participation. Fits a belief that MSTR will trade sideways or down while volatility remains high enough to sustain call premiums.

• ULTY: Investors seeking weekly income from diversified equity exposure without single-name concentration risk, and who value the volatility-responsive design (higher payouts when holdings gyrate more) as a hedge against write-down risk during calm markets. If implied volatility in MSTR collapses or if the stock stabilizes at a lower level, call premiums will shrink and the fund may need to dip into principal or reduce distributions. Weekly payout frequency accelerates any shortfall visibility.

• Single-stock concentration and headline risk. MSTY's entire return profile depends on MicroStrategy's stock price and implied volatility. Company-specific news—earnings misses, regulatory action, leadership changes, or shifts in its bitcoin-holding strategy—can crater both the share price and the call premium that funds distributions, creating a two-way hit.

• Call cap limits recovery upside. Both funds cap gains through call assignment. MSTY in particular: if MSTR rallies sharply, your shares will be called away at the strike. ULTY rotates holdings, so the cap resets, but assignment still locks you out of rallies in individual names.

• Derivative liquidity and counterparty risk. Both funds rely on liquid options markets to write and roll calls. A spike in bid-ask spreads or counterparty stress could impair the fund's ability to execute its strategy at quoted premiums, forcing it to hold stale positions or accept wider slippage.

• Beta amplification in drawdowns. MSTY's 2.5604 makes it roughly 2.5 times as sensitive to equity-market selloffs as the broad market. In a sharp correction, MSTY will fall faster than ULTY, and falling share prices also erode the call premiums that support distributions.

Bottom line

If you want maximum income from a conviction bet on MicroStrategy and can tolerate both upside caps and concentrated single-stock risk, MSTY's 98.88% yield is the draw. If you prefer diversified exposure with a volatility kicker and greater cushion against headline risk, ULTY's 59.55% and basket approach trade some income for stability. Both rely on sustained options-market depth and volatility to deliver their promised yields; past performance doesn't guarantee future results, and neither fund has enough history to validate long-term sustainability.
