GraniteShares YieldBOOST Semiconductor ETF (NASDAQ: SEMY) is an actively managed exchange-traded fund that seeks to generate high current income through a systematic options strategy; the fund primarily sells put options on leveraged exchange-traded funds designed to deliver 3x the daily performance of the NYSE Semiconductor Index (ICESEMI), while providing secondary exposure to the underlying leveraged ETF's performance subject to a cap on gains and potential downside protection via option premiums. SEMY targets investors seeking income linked to the semiconductor sector, a key area in digital innovation, artificial intelligence, and technology growth; it distributes income weekly and employs holdings including cash equivalents, U.S. Treasury bills, and targeted derivatives.
Launched on November 18, 2025, SEMY represents a recent expansion of GraniteShares' YieldBOOST ETF family, which alongside the simultaneous debut of the YieldBOOST Gold Miners ETF (NASDAQ: NUGY), broadens options-based income solutions tied to high-growth sectors; this follows other 2025 YieldBOOST launches such as fund-of-funds ETFs YBST and YBTY in December, and earlier single-theme products like those on Riot Platforms and Hims & Hers Health. GraniteShares, the ETF's issuer founded in 2016 and headquartered in New York, New York, manages a diverse lineup of over 10 billion dollars in assets under management as of late 2025, encompassing leveraged single-stock ETFs, commodity funds, high-income strategies, and short/leveraged ETPs listed across U.S. and European exchanges including NASDAQ, London Stock Exchange, and others in the UK, Italy, France, and Germany.
