If you've gone looking for high-yield investments, you've probably stumbled onto YieldMax ETFs — funds with tickers like MSTY, ULTY, TSLY, and CONY — advertising jaw-dropping "yields" of 50%, 80%, even 100%+ a year, paid monthly (and in ULTY's case, weekly). Those numbers are real headline figures. But before anyone is tempted by them, it's essential to understand how those payouts are generated — because they come with risks that are very easy to miss and that have cost a lot of beginners real money.
This is an honest explainer, not a sales pitch. We'll cover what these funds are, where the money comes from, and the two concepts — NAV erosion and return of capital — that matter most.
What YieldMax ETFs Actually Are
Each YieldMax fund is tied to a single underlying stock and uses an options strategy (a "synthetic covered call") to squeeze income out of that stock's price swings. The wilder the stock, the bigger the option premiums — which is why YieldMax built funds around the market's most volatile names:
| Ticker | Tied To | Pays |
|---|---|---|
| MSTY | MicroStrategy (a Bitcoin-heavy stock) | Monthly |
| TSLY | Tesla | Monthly |
| NVDY | Nvidia | Monthly |
| CONY | Coinbase | Monthly |
| ULTY | An actively managed mix of names | Weekly |
Note what this means: these are not diversified like SCHD or an index fund. With MSTY or TSLY, your fortunes are tied to one company's stock — concentrated, high-risk territory.
Where the Huge "Yield" Comes From
The fund sells options on its underlying stock and collects premiums (fees). Because these stocks are extremely volatile, the premiums are large, and the fund pays most of them out as distributions. That's the engine behind a "100% yield."
But here's the catch that the headline number hides: a covered-call strategy caps your upside. When the underlying stock soars, the fund can't fully follow it — it sold away those gains for premium income. Yet when the stock falls, the fund still feels most of the drop. Over time, that lopsided trade-off tends to drag the fund's share price downward.
The Big One: "NAV Erosion"
NAV stands for Net Asset Value — essentially the fund's share price. NAV erosion means the share price tends to grind down over time, even while the fund pays those big distributions. You collect fat monthly checks, but the value of your shares may be shrinking underneath you.
The danger: a high distribution can mask a declining share price, so your total return may be far lower than the "yield" suggests.
The Other One: "Return of Capital"
Part of a YieldMax distribution is often classified as "return of capital" (ROC). In plain terms, that means the fund is handing you back some of your own invested money and counting it as part of the payout. It can look like income, but a portion of it isn't profit — it's your own capital coming home. That's a big reason the advertised "yield" can overstate what you're truly earning.
Yield Is Not the Same as Total Return
This is the single most important idea in this article. Total return = the change in share price plus the distributions you received. A fund can pay a 100% distribution and still leave you with a negative total return if the share price falls far enough. The headline yield tells you how much cash is being paid out — not whether you're actually coming out ahead.
Other Things to Know
- High fees. YieldMax funds typically charge around 0.99% per year — far more than the 0.03–0.06% of a plain index or SCHD.
- Variable payouts. Distributions change every period based on volatility — they are not a stable, predictable income.
- Tax complexity. The income (and return-of-capital portions) can be taxed in complicated ways; many holders prefer to use tax-advantaged accounts and consult a tax professional.
- Single-stock risk. MSTY, TSLY, NVDY, and CONY each ride one volatile company. If that stock falls hard, the fund usually does too.
- They're new. These products have short track records, mostly launched in the 2020s, so there's limited history through a full market cycle.
Who Uses Them — and a Word of Caution
Some experienced, income-focused investors use YieldMax funds deliberately, with eyes open: as a small, high-risk slice of a portfolio, sometimes reinvesting distributions to offset NAV erosion, fully aware they may be trading long-term growth for current cash. That's a legitimate (if aggressive) choice for someone who understands the mechanics.
The danger is for beginners who see "100% yield" and assume it means doubling their money safely. It does not. These are among the most complex and volatile products marketed to everyday investors. If you don't fully understand covered calls, NAV erosion, and return of capital, that's a strong signal to learn more — or stick to simpler, diversified options like a dividend ETF — before putting money in.
A Calmer Alternative to Compare Against
It's worth seeing the contrast. A diversified dividend-growth approach yielding a steady ~3.5% with a rising share price often produces a better total return over time than a headline-grabbing fund whose price erodes. Model a steady-yield scenario in the calculator and compare it to the all-or-nothing appeal of an ultra-high yield.

YieldMax ETFs (MSTY, ULTY, TSLY, CONY, NVDY and others) use options on a single volatile stock to generate extremely high monthly or weekly payouts. The headline yields are real, but so are the risks: the share price often erodes over time, part of the distribution can be a return of your own capital, fees are high, and you're concentrated in one stock. The yield is not the same as your total return — and for these products, that distinction is everything. They are advanced, high-risk tools, not a free lunch. Understand exactly how they work (and ideally talk to a financial professional) before risking money in them.
