State Street Launches 90/10 Endowment Strategy ETF With UC Investments

State Street Investment Management launched the SPDR UC Investments 90/10 Endowment Strategy Index ETF (UCBG) with a $2.5 billion anchor investment from UC Investments, making it the largest-ever launch of a U.S.-listed ETF, excluding conversions. Developed with UC Investments, UCBG packages an endowment-inspired strategy into an ETF, allocating 90% to the S&P 500 and 10% to short-duration investment-grade corporate bonds. The approach draws on UC’s $7.9 billion Blue and Gold Endowment Pool and emphasizes low-cost, liquid public-market exposure.
