GraniteShares YieldBOOST SMCI ETF (SMYY) is an exchange-traded fund that seeks current income through options strategies, primarily by selling put options on leveraged exchange-traded funds tracking 2x the daily performance of Super Micro Computer Inc. (NASDAQ: SMCI); its secondary objective provides exposure to the underlying leveraged ETFs subject to limits on potential investment gains. The fund distributes income weekly and invests at least 80% of its net assets in derivatives contracts tied to the underlying leveraged SMCI ETFs. GraniteShares, the fund's issuer founded in 2016 and headquartered at 222 Broadway in New York, New York, manages a diverse lineup of U.S. and European exchange-traded products including leveraged and inverse single-stock ETFs, commodity funds, high-income strategies, and its expanding YieldBOOST suite focused on option-writing for income generation.
SMYY launched on September 30, 2025, as part of GraniteShares' rapid YieldBOOST expansion, which has introduced multiple new ETFs in 2025 targeting high-growth stocks and themes such as HOOD (HOYY), META, ABA, RIOT (RTYY), HIMS (HMYY), semiconductors (SEMY), gold miners (NUGY), MSTR (MTYY), and PLTR (PLYY). This growth reflects GraniteShares' strategic shift toward options-based income products on leveraged single-stock ETFs, with the YieldBOOST suite surpassing $649.5 million in assets under management as of November 28, 2025, amid the firm's overall AUM reaching over $11.1 billion. The company, backed by Bain Capital Ventures in its Series A funding, operates globally with U.S. listings on NASDAQ and European products across London, Italy, France, and Germany stock exchanges, serving high-conviction investors seeking leveraged, inverse, and alternative exposures.
