Shelton Capital Management has entered into an asset purchase agreement with Essex Investment Management Company, adding an investment team focused on micro-cap, small-cap, mid-cap, and thematic growth strategies to Shelton’s platform.
Boston-based Essex is an SEC-registered investment adviser managing more than $725 million in assets. Its investment capabilities are organized across two portfolio management teams serving institutional investors, family offices, and high-net-worth clients.
Essex also serves as sub-advisor to two mutual funds offered through Equitable Investment Management’s 1290 Funds and the Pear Tree Funds family. Under the agreement, the Essex team will gain access to Shelton’s marketing technology, investment operations infrastructure, and client-service platform while maintaining continuity of its investment philosophy and portfolio management organization.
Founded in 1976, Essex has built strategies spanning micro-cap, small-cap, and mid-cap growth equities, along with global thematic and environmental investment opportunities. The firm is headquartered in Boston and also operates an office in Evanston, Illinois.
The transaction adds to a series of acquisitions by Shelton in 2026. The firm has also acquired Stringer Asset Management and STF Management as part of its strategy to expand investment capabilities while centralizing operational, marketing, and distribution resources.
Shelton manages more than $8 billion in assets as of September 30, 2026. Its investment lineup includes mutual funds, ETFs, ETF-based portfolios, separately managed accounts, fixed income, U.S. and international equities, ESG strategies, and equity income products.
