GraniteShares YieldBoost Single Stock Universe ETF (YBST) is an actively managed exchange-traded fund that seeks to generate weekly income through investments primarily in a diversified portfolio of GraniteShares YieldBOOST™ ETFs; each underlying YieldBOOST™ ETF employs an options-based strategy, such as writing covered calls, on leveraged ETFs tracking individual U.S.-listed securities including popular names like Tesla (TSYY), NVIDIA (NVYY), Coinbase (COYY), Amazon (AMYY), Meta (MTYY), Palantir (PLY), Super Micro (SMYY), Hims & Hers (HMYY), Riot Platforms (RTYY), and others. The fund maintains an equal-weighted allocation across its underlying YieldBOOST™ ETFs, with monthly rebalancing, and targets high-yielding options premiums from innovative sectors such as technology, digital assets, and consumer health; its primary objective is current income via weekly distributions, with a secondary focus on broad exposure to the GraniteShares YieldBOOST™ ecosystem, complemented by a 30-Day SEC Yield and distribution rate reflecting net investment income excluding option premiums. YBST trades on Nasdaq and forms part of GraniteShares' broader lineup of income-oriented, options-enhanced ETFs designed for high-conviction investors seeking enhanced yields on single-stock exposures. Founded in 2016 by William Rhind and headquartered in New York with European operations launched in London in 2019, GraniteShares manages over $10.9 billion in assets under management as of September 2025 and operates globally across major U.S. and European exchanges, offering products including physically backed commodities ETFs, leveraged and short single-stock ETPs, high-income strategies, and disruptive technology baskets. In December 2025, GraniteShares launched YBST alongside the YieldBoost TopYielders ETF (YBTY) as the first fund-of-funds structures in its YieldBOOST™ platform, providing diversified and targeted access to the series' single-stock options income strategies; this expansion followed earlier 2025 additions like RTYY and HMYY in December and others such as Meta- and Alibaba-linked ETFs in October, building on a platform that surpassed $649.5 million in AUM by late November 2025.
