YieldMax MRNA Option Income Strategy ETF (MRNY) is an actively managed exchange-traded fund that seeks current monthly income and capped exposure to the share price return of Moderna Inc. (MRNA) through a synthetic covered call strategy collateralized by cash and short-term U.S. Treasurys; the strategy involves synthetic long exposure to MRNA via at-the-money call and put options with one- to six-month terms, covered call writing on short-duration out-of-the-money call options (0%-15% above current MRNA share price), and U.S. Treasury securities for collateral, without direct investment in MRNA shares or entitlement to its dividends. The fund employs both standardized exchange-traded and FLEX options, generating income from option premiums while limiting upside participation in MRNA price gains and exposing investors fully to downside risk. Launched on October 23, 2023 and domiciled in the United States with administrative operations in Milwaukee, Wisconsin, MRNY operates within the healthcare/biotechnology sector targeting income-focused investors seeking yields from single-issuer option strategies on volatile equities. In recent developments, YieldMax transitioned MRNY and other ETFs from monthly to weekly distributions effective October 14, 2025 to enhance shareholder flexibility and access; the firm launched the Performance and Distribution Target 25 ETF family in November 2025, including new single-stock option income products like MSST and NVDA-focused funds; and integrated enhanced trading capabilities via ZEGA Financial and Tidal Investments in January 2025 to support portfolio growth, alongside a March 2025 partnership with HANetf for its first UCITS ETF (YMAG) in Europe. YieldMax ETFs, advised by Tidal Investments LLC with ZEGA Financial as sub-adviser and distributed by Foreside Fund Services, LLC, manages a suite of over 40 similar single-issuer and sector option income strategies listed primarily on U.S. exchanges.
