YieldMax has pioneered a significant niche in the market with its single-stock covered call ETFs. Taking advantage of the ramped-up volatility that the Magnificent 7 tech stocks injected into the S&P 500, YieldMax capitalized on the timing with their covered-call platforms for each one of the Magnificent 7 stocks, and has done a lot of business with them.
One of the biggest attractions for the YieldMax single-stock ETF series is their inordinately high dividend yields. For example, the YieldMax MSFT Option Income Strategy ETF (NYSE: MSFO) boasts an eye-popping 44.17% yield at the time of this writing. However, it comes with an NAV beartrap with sharp teeth as its trade-off.
YieldMax MSFT Option Income Strategy ETF

YieldMax pioneered single-stock, covered-call income ETFs specifically for Magnificent 7 stocks, due to their volatility. MSFO is their Microsoft ETF.
MSFO is a YieldMax single-stock ETF that generates its dividends from covered-call spread writing against Microsoft, Inc. (NASDAQ: MSFT | MSFT Price Prediction) stock. The ETF’s active management opens and closes these call option positions weekly, and MSFO pays out accordingly. The strategy attempts to mitigate downside risk while drawing income from option premiums and still capture at least a portion of upside gains on the underlying Microsoft stock movement.

Robbing Paul to Pay Paul

MSFO’s NAV depletion shares some mechanical similarities with Social Security’s looming insolvency, except whereas Congress is the entity taking from Social Security, MSFO is taking from itself,
Social Security’s looming insolvency perfectly illustrates the notion of “robbing Peter to pay Paul”. The insolvency is primarily created by repeated Congressional borrowing from the Social Security trust fund for its spending profligacy, essentially leaving behind worthless I.O.U.s. In the case of MSFO, it is an unfortunate case of “robbing Paul to pay Paul.”
MSFO is paying a gigantic dividend yield, but NAV has dropped precipitously, with double-digit losses from 2025 and continuing through 2026. Translation: MSFO has had to tap into NAV to continue paying out dividends when premiums fell short of target amounts. This means that in the aggregate, investors’ dividends has been a net return of their own invested funds – after the YieldMax management expenses.
To be fair, MSFT common stock has had difficulties this past year. Billions in CapEx for A.I. development has given many analysts pause to reconsider their earlier projections of MSFT earnings vs. revenues for 2026. The intrinsic upside volatility that MSFT would normally experience had become erratic.
Nevertheless, investors who held MSFT stock still made better upside gains than those who held MSFO. Apart from dividends, not only did MSFO not capture any of the reduced MSFT upside in the past year, but the NAV loss from tapping into the warchest to payout dividends put MSFO further down the hole. This would seem to indicate that the call spread strategy might need to be adjusted. Any premiums generated by the calls are insufficient. Perhaps the calls are too restrictively hedged to the point of capturing upside to preserve NAV. The result is that the premiums are a revolving door, the NAV gets little to none of its tracked stock upside, and loses value intrinsically any week that MSFO is short of its weekly target.

In Conclusion:

The long term odds are in favor of MSFO and MSFT righting their ship’s course, but the short term odds are still risky for investors.
YieldMax managers aren’t incompetent. They will find the right formula to tweak the MSFO strategy to get things on firmer footing. Will dividends have to be reduced? Possibly. Will NAV upside tracking with MSFT be restored to at least a reasonable percentage ? Quite likely. Will MSFT resume its big double-digit annual gains that made it a $3 trillion company? Eventually.
However, until circumstances change, MSFO will continue to be attractive for its 44% yield, but full of land mines for those investors unaware of the NAV pitfall risks. It’s important to know the rules of the game before taking a seat at the casino table.
