United States Commodity Index Fund, LP (USCI) is a Delaware limited partnership that issues units representing a fractional undivided beneficial interest in the fund's net assets, which seek to track the SummerHaven Dynamic Commodity Index Total Return (the "Index"). The Index tracks a diversified portfolio of 14 commodity futures contracts selected and weighted based on a proprietary quantitative methodology that aims to identify commodities with historically positive returns relative to their risk, with roll weights adjusted monthly to reflect the most attractive contract months; the fund's investments include futures contracts on energy commodities such as crude oil, natural gas, unleaded gasoline, heating oil, and brent crude; agricultural commodities including corn, soybeans, soybean oil, wheat, cotton, sugar, cocoa, and coffee; and metals such as gold, silver, platinum, and copper. USCI offers investors exposure to commodities through exchange-traded shares listed on the NYSE Arca under the ticker USCI, with units redeemable only in blocks of 50,000 by authorized participants; the fund employs leverage through futures contracts and collateralizes its positions with U.S. Treasury securities, cash, and money market instruments. The partnership operates primarily in the United States, with its headquarters in Oakland, California, and was formed in 2010 as part of the USCF Investments family of exchange-traded products sponsored by Wainwright Holdings, Inc. In recent years, USCI has maintained its focus on dynamic commodity indexing amid volatile markets, with no major acquisitions, funding rounds, or structural reorganizations reported in the last 1-2 years; ongoing portfolio rebalancing aligns with SummerHaven Indices LLC's methodology updates, and the fund continues to serve institutional and retail investors seeking commodity diversification beyond traditional benchmarks like the Bloomberg Commodity Index.
