YieldMax MSFT Option Income Strategy ETF (MSFO) is an actively managed exchange-traded fund that seeks to generate current monthly income with capped exposure to the share price appreciation of Microsoft Corporation (MSFT) common stock through a synthetic covered call options strategy collateralized by cash and U.S. Treasurys; the fund employs both standardized exchange-traded options and FLEX options, selling/writing call options on MSFT while purchasing out-of-the-money calls to manage potential losses from upside moves, without direct investment in MSFT shares or entitlement to its dividends. Launched on August 24, 2023, and issued by Tidal Trust II under the YieldMax ETFs brand with sub-advisory from ZEGA Financial, LLC, MSFO trades on the NYSE Arca and targets income-seeking investors exposed to the information technology sector, particularly systems software via MSFT's performance. The fund holds a portfolio including options contracts, U.S. Treasurys, and cash equivalents, with an expense ratio of 1.07% and assets under management of approximately $148 million as of late 2025.
Headquartered through its service providers in Milwaukee, Wisconsin, with Tidal Financial Group operations spanning Chicago, New York, Milwaukee, and other U.S. locations, YieldMax operates as part of a broader platform managing over 60 single-stock and fund-of-option income ETFs focused on high-yield strategies across technology, semiconductors, and other sectors. In recent developments, YieldMax ETFs announced the integration of ZEGA Financial and Tidal teams in January 2025 to enhance trading capabilities and operational efficiency, supporting expanded product offerings; the platform has continued monthly and weekly distribution announcements throughout 2025, including for MSFO, amid growth in assets and new ETF launches such as funds-of-funds and sector-specific strategies. Ongoing SEC filings reflect portfolio adjustments and new series additions to Tidal Trust II, reinforcing YieldMax's focus on innovative option income products without reported acquisitions, funding rounds, or name changes for MSFO specifically in the last 1-2 years.
