Stephens Investment Management Group, LLC

Stephens Investment Management Group (SIMG) advises institutional clients, high‑net‑worth individuals, pension plans, foundations, corporations and investment companies, providing discretionary portfolio management across separately managed accounts, mutual funds, collective investment trusts and model‑based programs. The firm concentrates on long‑only U.S. equity strategies—primarily small‑ and mid‑cap growth—and does not offer standalone financial planning or target non‑high‑net‑worth retail individuals.

SIMG’s investment process is a bottom‑up fundamental research approach augmented by quantitative screening and sector specialization by a five‑member portfolio team, operating seven strategy models including an Artificial Intelligence and Automation strategy that can produce significant sector and international exposure. Managers deliver model portfolios for separate accounts, wrap programs and pooled vehicles, use enterprise AI tools as a research input (not the sole determinant of decisions), and permit reasonable client‑imposed restrictions rather than tailoring fully bespoke portfolios.

Distinctive features include affiliations with Stephens Inc., an entity that is a registered municipal advisor, broker‑dealer and provider of pension consulting services, and a substantial business serving investment companies and pooled vehicles — mutual fund assets represented about 71% of SIMG’s assets under management at year‑end 2025. The firm at times uses performance‑based or hybrid fee arrangements (including a fulcrum fee arrangement for the Vanguard Explorer Fund), discloses predecessor performance from its prior activity through Stephens Inc., and manages side‑by‑side accounts with written policies intended to address allocation and execution conflicts.
