SIMCO
SIMCO was founded in 1986 in Berwyn, Pennsylvania, by a group of investment professionals who saw an opportunity to provide institutional-quality active management to a broader set of clients. The firm has grown into a diversified investment manager with offices in Westport, Boston, and San Francisco, employing over 150 people. SIMCO's strategy spans multiple asset classes, including U.S. and non-U.S. equities, fixed income, private credit, infrastructure, and real assets. The firm uses a fundamental, research-driven approach to identify mispriced securities and opportunities. Confirmed positions include holdings in corporate bonds, mortgage-backed securities, and infrastructure debt. SIMCO invests primarily in North America and Europe, with some exposure to emerging markets. The firm manages roughly $25B in assets (per public record, 2026), though it does not publicly disclose a precise AUM figure. SIMCO's team includes over 150 investment professionals. The firm has no publicly confirmed recent operational events of note. SIMCO's structural differentiator is its focus on high-conviction active management in an era of passive investing. The firm runs concentrated portfolios with a long-term horizon, distinguishing itself from more index-hugging peers. This approach appeals to institutional clients seeking alpha generation without the costs of a broader multi-manager structure.

How does SIMCO source investment opportunities?

The firm's analysts and portfolio managers conduct independent research, meet with management teams, and analyze industry dynamics. In private markets, SIMCO sources opportunities through direct relationships with sponsors, banks, and intermediaries.
Does SIMCO manage assets for family offices or only institutions?
SIMCO primarily serves institutional clients, including corporate pension plans, endowments, foundations, and public funds. The firm also manages assets for high-net-worth individuals through separately managed accounts, but family offices are not a core constituency.

In private markets, the firm focuses on direct credit and infrastructure investments, targeting long-duration, income-generating assets. SIMCO does not typically engage in venture capital or early-stage equity.
Does SIMCO offer direct co-investment opportunities to clients?
SIMCO structures investments as commingled funds and separately managed accounts. The firm may offer co-investment opportunities in private credit and infrastructure deals to qualified clients, but this is not a primary distribution channel (per public record).

What is SIMCO's investment philosophy?
