USCF SummerHaven SHPEI Index Fund (Ticker: BUY) is an exchange-traded fund managed by U.S. Commodity Funds LLC that seeks to track the performance, before fees and expenses, of the SummerHaven Shipping Index (SHPEI), which measures the performance of a rules-based index of dry bulk shipping stocks selected and weighted by shipping rates and vessel capacity. The fund provides investors with targeted exposure to the dry bulk shipping sector through its holdings in global shipping companies engaged in the transportation of commodities such as iron ore, coal, and grains; it employs a passive management strategy focused on replicating the index's composition, which is rebalanced quarterly based on proprietary shipping data from the Baltic Exchange and Clarksons Research. Primary products and services include shares traded on major U.S. exchanges like the NYSE Arca, with assets under management emphasizing cap-weighted positions in leading dry bulk operators across capesize, panamax, supramax, and handysize vessel segments. Founded in 2015 and headquartered in Oakland, California, as part of the U.S. Commodity Funds family—which also manages other commodity-focused ETFs—the fund operates primarily in U.S. capital markets while providing indirect exposure to international shipping operations in regions including Asia, Europe, and the Americas targeting institutional and retail investors interested in cyclical commodity transport sectors. Recent developments include a strategic rebranding and ticker change to BUY in late 2024 to better reflect its focused shipping equity strategy and enhance market visibility amid rising global trade volumes; additionally, in 2025, the fund expanded its index methodology to incorporate real-time vessel tracking data integrations, boosting liquidity and attracting over $50 million in new inflows during the third quarter.
