SEI Institutional Managed Trust U.S. Managed Volatility Fund Class I (SEVIX) operates as an open-end mutual fund within the SEI Institutional Managed Trust, a series trust managed by SEI Investments Management Corporation. The fund seeks total return by investing principally in U.S. equity securities selected for their potential to generate lower volatility relative to the broader U.S. equity market; it employs a multi-manager approach, allocating assets among unaffiliated sub-advisers such as LSV Asset Management, Pacer Advisors, and others who apply proprietary quantitative models emphasizing low-volatility factors, quality metrics, and risk-controlled strategies. Core offerings include Class I shares targeted at institutional investors with high minimum investments, featuring a focus on large- and mid-cap U.S. stocks while limiting exposure to high-volatility names; the fund also maintains cash equivalents and derivatives for risk management. Headquartered in Oaks, Pennsylvania, the SEI Institutional Managed Trust traces its origins to SEI Investments' institutional platform established in the 1980s, with global operations spanning North America, Europe, and Asia through SEI's broader network serving institutional clients including retirement plans, endowments, and foundations. In recent developments, the fund underwent a sub-adviser transition in 2024, adding new managers to enhance diversification and alpha generation amid market volatility; it also benefited from SEI Investments' strategic expansion into enhanced indexing strategies, including a 2025 launch of complementary low-volatility ETFs under the SEI brand.
