SGI Enhanced Core ETF (USDX) is an actively managed exchange-traded fund that seeks to generate current income and enhanced yield through a diversified portfolio of higher-yielding, high-quality short-term money market instruments, money market mutual funds, short-term U.S. Treasury securities, and other fixed-income debt-related instruments; it further employs ultra-short-term options strategies, including actively traded put and call options on the S&P 500 Index or other broad benchmark indices, to boost income while emphasizing risk control and reduced volatility. The fund utilizes a managed-risk approach with fundamental and quantitative analysis to outperform traditional core strategies in dividend yields and income generation, targeting investors focused on capital preservation amid inflation, interest rate fluctuations, and market volatility. USDX trades on the Nasdaq exchange and benchmarks against the S&P 500 Index, with a net expense ratio of 1.05% and assets under management exceeding $339 million as of late 2025.
Launched on February 29, 2024, by The RBB Fund, Inc. and co-managed by Summit Global Investments, LLC (founded in 2010 and headquartered in Bountiful, Utah) and SG Trading Solutions, LLC, USDX operates primarily in U.S. fixed-income and derivatives markets. The ETF is distributed by Quasar Distributors, LLC and forms part of Summit Global Investments' expanding lineup of five ETFs introduced within the past two years.
Recent milestones include surpassing $100 million in assets under management in less than five months post-launch in August 2024, prompting Summit Global Investments to celebrate by ringing the Nasdaq closing bell on August 9, 2024. Ongoing developments feature regular dividend declarations, such as $0.86813 per share ex-dividend on December 30, 2024, and $0.0513 per share in early 2025, alongside new institutional investments like Flow Traders U.S. LLC's acquisition of a 0.30% stake in Q2 2025. Summit Global Investments continues its ETF expansion with launches like the SGI Enhanced Global Income ETF (GINX) alongside USDX in March 2024, reinforcing its focus on income-oriented, risk-managed products.
