YieldMax Magnificent 7 Fund of Option Income ETFs (YMAG) and YieldMax Ultra Option Income Strategy ETF (ULTY) generate double-digit yields through synthetic covered call strategies that sell call options against underlying stocks, but both funds have experienced NAV erosion with YMAG down 7% year-to-date while Tesla (TSLA) fell 13% and Nvidia (NVDA) dropped 3%, with distributions increasingly comprised of return of capital rather than earned income.

The funds’ income depends on elevated volatility (VIX at 27.29) to generate option premiums, but when the VIX compresses below 15, premium income collapses and distributions shrink, creating a sustainability risk as investors gradually receive their own principal returned rather than genuine yield.

A recent study identified one single habit that doubled Americans’ retirement savings and moved retirement from dream, to reality. Read more here.

YieldMax Magnificent 7 Fund of Option Income ETFs (NYSEARCA:YMAG) and YieldMax Ultra Option Income Strategy ETF (NYSEARCA:ULTY) advertise something genuinely appealing: double-digit yields from some of the most-traded stocks in the world. YMAG wraps individual YieldMax covered call ETFs on all seven Magnificent 7 names into a single fund. ULTY targets even higher distributions across a basket of high-volatility holdings. Both pay weekly. Both carry yields that dwarf anything available from a money market or Treasury. And both are slowly returning your own money to you in the process.

Every YieldMax product runs a synthetic covered call strategy. The fund holds a position in the underlying stock and sells call options against it, collecting premium that gets paid out as distributions. The sold calls cap how much the fund participates in any upside move. When the underlying stock rallies past the strike price, the fund misses the gain, and the premium collected does not come close to compensating for that missed appreciation over time.

YMAG holds seven single-stock YieldMax ETFs in roughly equal weights, with each component (NVDY for Nvidia, TSLY for Tesla, and so on) running its own covered call overlay. Bundling seven stocks together feels like diversification, but it does not solve the underlying problem. Every component is capping upside and collecting premium, and the NAV decay mechanism runs in parallel across all seven positions simultaneously.

Read: Data Shows One Habit Doubles American’s Savings And Boosts Retirement

Most Americans drastically underestimate how much they need to retire and overestimate how prepared they are. But data shows that people with one habit have more than double the savings of those who don’t.

YMAG is down about 7% year-to-date through March 13, 2026, while the underlying Magnificent 7 stocks have themselves pulled back. Tesla (NASDAQ:TSLA) is down 13% year-to-date with vehicle deliveries declining 16% year-over-year in Q4 2025 and full-year net income falling nearly 47%. Nvidia (NASDAQ:NVDA) is down about 3% year-to-date despite reporting $68.13 billion in Q4 revenue, up 73% year-over-year. Nvidia's range-bound behavior after exceptional earnings illustrates the covered call problem precisely: when the underlying barely moves, there is limited NAV recovery and limited premium to collect.

The distribution history makes the erosion pattern concrete. ULTY paid monthly distributions ranging from $0.79 to $1.42 per share in 2024. By 2026, the fund shifted to weekly payments averaging roughly $0.47 to $0.52 per week. The frequency increase masks the decline in total payout per dollar invested. Meanwhile, ULTY's price has declined about 2.5% year-to-date and is essentially flat from its inception price two years ago, meaning the entire return has come from distributions, some portion of which represents return of capital rather than earned income.

Return of capital distributions are not income. They are the fund returning your own principal, which simultaneously reduces the NAV base that future distributions are calculated against. The yield looks high because the denominator keeps shrinking.

Options premiums are driven by implied volatility. The VIX currently sits at 27.29, up 53% over the past month, which is favorable for premium collection. But the same VIX data shows how quickly that changes: the index compressed to 13.47 in late December 2025 before the current spike. At that level, the covered call strategy generates far less premium, distributions compress, and the yield that attracted investors shrinks. YMAG's weekly distributions have already ranged from $0.05 to $0.29 per share in recent history, a nearly sixfold swing driven largely by volatility conditions.

Track the VIX weekly through FRED's VIXCLS series. A sustained move below 15 signals premium compression that will reduce distributions meaningfully. Watch YMAG's weekly distribution amounts relative to its current NAV: if distributions are running above what the fund can generate from premium alone, return of capital is filling the gap. YieldMax publishes distribution breakdowns on its website identifying the return of capital component each quarter. For ULTY, monitor the underlying holdings' implied volatility individually, since the fund's income depends on premium across a basket of speculative names including quantum computing stocks, crypto miners, and AI infrastructure companies that can go quiet for extended periods.

Investors drawn to these funds for income need to weigh whether the distributions they receive are genuinely earned yield or a gradual liquidation of principal dressed up as a paycheck. With volatility elevated, the premium environment is supportive. The question is what happens when it normalizes.

Most Americans drastically underestimate how much they need to retire and overestimate how prepared they are. But data shows that people with one habit have more than double the savings of those who don’t.

And no, it’s got nothing to do with increasing your income, savings, clipping coupons, or even cutting back on your lifestyle. It’s much more straightforward (and powerful) than any of that. Frankly, it’s shocking more people don’t adopt the habit given how easy it is.
