Teucrium AiLA Long-Short Base Metals Strategy ETF (OAIB) is an exchange-traded fund that seeks to track the total return performance, before fees and expenses, of the AiLA-S022 Index, providing long/short exposure to base metals commodity futures contracts including aluminum, copper, lead, nickel, tin, and zinc traded on the Chicago Mercantile Exchange and London Metals Exchange; the strategy employs a proprietary quantitative model incorporating micro- and macro-features analysis, portfolio metrics, and daily signals to determine asset allocation, which may range from 100% long or short on a single commodity to 100% cash. Sponsored by Teucrium Trading, LLC, founded in 2009 and headquartered in Burlington, Vermont, the ETF targets investors seeking market-neutral absolute returns in the commodities sector through a liquid, tax-efficient vehicle with 1099 treatment and a total net expense ratio of 1.64%. Launched on April 5, 2023, on NYSE Arca, OAIB represented Teucrium's first non-agricultural commodity offering, developed in partnership with AiLA Indices (powered by OPALai's AI-driven technology) following the prior launch of the related Teucrium AiLA Long-Short Agriculture Strategy ETF (OAIA). In a significant recent development, Teucrium Investment Advisors, LLC and the Board of Trustees of Listed Funds Trust approved the fund's liquidation due to an approximately 875% fee increase imposed by the London Metals Exchange on derived data usage for the AiLA-S022 Index, which OPALai deemed excessive after failed negotiations; the ETF ceased accepting creation orders on June 5, 2024, with full liquidation and distribution of proceeds to shareholders completed thereafter, rendering it inactive.
