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

Overview

AMZY and MSTY are single-stock covered call ETFs from YieldMax that generate income by selling call options on Amazon and MicroStrategy, respectively. Both funds hold the underlying stock and write weekly options against it, passing the premium to shareholders as distributions. The critical distinction: MSTY targets a bitcoin proxy (MSTR trades at a steep premium to its bitcoin holdings), while AMZY tracks a mega-cap cloud and e-commerce business. That structural difference—plus a dramatic gap in distribution rate—makes these funds serve very different investor needs.

How they differ

The most obvious difference is yield: MSTY distributes 70.51% annualized versus AMZY's 33.18%. That gap doesn't mean MSTY is twice as good—it reflects MSTR's extreme price volatility (52-week range of $19–$126), which inflates option premiums that the fund can harvest weekly. AMZN, by contrast, is far more stable, so call premiums are thinner. Second, MSTY has vastly more assets under management ($1.05 billion vs. $218 million), suggesting institutional adoption and better trading liquidity. Both charge similarly low expense ratios (1.03% vs. 1.09%), so fees are a wash. Third, and most important for risk: MSTY's compressed 52-week low of $19.17 versus its recent price of $22.83 signals recent recovery from a crash; AMZY's range ($10.61–$16.70) is tighter and more orderly. Both funds report zero beta, a technical artifact of their option-overlay structure that shouldn't be read as hedging—they're not.

Who each is best for

• AMZY: Investors seeking a more stable income stream from a quality mega-cap business, willing to cap upside in exchange for systematic weekly cash flow; suits tax-deductible accounts where the 33% yield won't create excess tax drag.

• MSTY: Experienced options traders or those with high risk tolerance who understand that bitcoin proxy volatility can inflate option premiums sharply, and who accept that NAV compression is the price of harvesting those premiums; best suited for taxable accounts where losses can be harvested.

Key risks to know

• NAV erosion from high yields: MSTY's 70% distribution rate exceeds typical equity total return; over time, the fund is likely to erode NAV unless MSTR's underlying value appreciates substantially. AMZY's 33% rate is less extreme but still suggests meaningful capital decay if Amazon's stock price stagnates.

• Single-stock concentration: Both funds hold only one name. An earnings miss, competitive setback, or sector rotation can crater the underlying price with no diversification offset. MSTR carries additional idiosyncratic risk tied to bitcoin holdings and leverage decisions.

• Call-writing cap on upside: If the underlying rallies hard, call assignments will lock in gains; shareholders miss the move above the strike. This is a feature, not a bug, but it's a structural trade-off.

• Volatility-driven premium risk: MSTY's high yield depends on MSTR's volatility remaining elevated. If MSTR stabilizes, option premiums shrink, and so does the fund's income. AMZN is less prone to this, but large market downturns can still compress premiums across both.

• Credit and leverage risk (MSTY): MSTR carries debt and uses leverage in its bitcoin holdings. If bitcoin crashes sharply or MSTR's credit conditions tighten, the underlying could fall faster than the option overlay can protect against.

Bottom line

If you want a high-income stream from a fortress mega-cap business and can tolerate modest NAV compression, AMZY's lower yield and larger, more stable underlying suit a buy-and-hold income strategy. If you're hunting maximum current income and accept that it may come partly from NAV decay, understand single-stock and leverage risks, and believe in MSTR's bitcoin thesis, MSTY's 70% distribution and larger AUM offer thicker premiums. Both are options-based plays, not passive equity holdings—they exchange capital appreciation for income, and past premium levels don't predict future ones.
