Overview
BLOX and ULTY are both weekly-distribution ETFs launched in early 2024 that use options strategies to generate outsized current income. BLOX targets crypto-related equities with an options overlay, while ULTY focuses on high-volatility stocks via covered calls. Both offer distribution rates well above historical equity yields, but they're fundamentally different bets: one on the crypto sector, the other on systematic income harvesting from volatile names.
How they differ
The single biggest difference is their underlying exposure. BLOX holds crypto-related companies—software, mining, exchange operators—while ULTY holds a basket of high-volatility stocks across sectors. That's a strategy choice that dwarfs everything else: BLOX is a sector bet, ULTY is a volatility bet.
Second, ULTY's yield is nearly double BLOX's. ULTY distributes 66.87% annually versus BLOX's 34.69%. That gap suggests ULTY's covered-call strategy is capturing more premium from market turbulence, or possibly relying more heavily on return-of-capital distributions as underlying stocks stagnate or decline. ULTY also costs more to own at 1.30% expense ratio versus BLOX's 0.99%.
Third, size and longevity diverge. ULTY has $854.7 million in AUM versus BLOX's $267.7 million, suggesting more liquidity and redemption capacity. Both funds are brand-new—BLOX arrived March 1, 2024; ULTY February 21, 2024—so neither has weathered a full market cycle.
Who each is best for
BLOX: Investors with high risk tolerance who believe in crypto's long-term fundamentals and want weekly income from sector exposure; best held in tax-advantaged accounts given the high turnover and distribution frequency that generate short-term capital gains.
ULTY: Income-focused traders comfortable with systematic call-selling who accept that upside will be capped; suitable for those already concentrated in high-volatility stocks seeking to harvest volatility premium, provided they understand covered-call mechanics and have a low horizon for principal stability.
Key risks to know
- NAV erosion from unsustainable yields. ULTY's 66.87% annual distribution rate exceeds typical equity total returns; over time, the fund is likely to return capital to shareholders, eroding NAV unless underlying stocks deliver exceptional appreciation or volatility stays elevated.
- Options assignment and upside cap. Both funds use covered calls (BLOX via broader options, ULTY explicitly), meaning shares are called away if underlying stocks rally sharply. Investors sacrifice outsized gains for steady income, a tradeoff that hurts in strong bull markets.
- Crypto sector concentration and regulatory risk. BLOX's exposure to crypto-related equities carries both the volatility of the sector and the risk of tightening regulation, delisting, or bankruptcy among holdings—individual companies in crypto have failed suddenly.
- Funds' extreme youth and beta anomalies. Both launched within weeks of each other, so no fund has proved its strategy through a full cycle. The reported beta of 0.0 for both is implausible and likely reflects incomplete or erroneous data; treat this metric with skepticism.
Bottom line
If you're betting on crypto and want regular distributions from that exposure, BLOX offers lower fees and more modest yield targets. If you're seeking maximum current income from liquid, high-volatility equities and can accept that your principal may erode, ULTY's 66.87% yield is the trade-off—but understand you're accepting call risk and the likelihood of return-of-capital distributions. Both are experimental products barely six months old; past performance doesn't predict future results, and option-driven strategies can behave unexpectedly in market dislocations.
