Janus Henderson Triton Fund (JGMIX) is an actively managed open-end mutual fund that seeks long-term growth of capital by investing primarily in small- and mid-cap growth equities, focusing on companies with differentiated business models, sustainable competitive advantages, and potential to expand market share across economic cycles. The fund offers multiple share classes including Class S (JGMIX), Class A (JGMAX), Class C (JGMCX), Class I (JSMGX), Class N (JGMNX), Class R (JGMRX), and Class T (JATTX), with total net assets of approximately $5.70 billion as of June 30, 2025; it maintains a portfolio of around 118 equity holdings characterized by a weighted average market capitalization of $9.78 billion, high active share of 87.41%, and sector allocations led by industrials (24.82%), health care (20.37%), and information technology (18.91%). Primarily targeting U.S. small- and mid-cap growth opportunities benchmarked against the Russell 2500 Growth Index, the fund employs in-depth fundamental research by a dedicated team of analysts and portfolio managers—Jonathan Coleman (since 2013), Scott Stutzman (since 2016), and Aaron Schaechterle (since 2023)—with approximately 93% North American exposure, modest international allocations in Europe (5%) and emerging regions, and low annual turnover of 21.31%. Launched on February 25, 2005, and domiciled in the United States with management by Janus Henderson Investors, headquartered in Denver, Colorado, the fund categorizes within the Morningstar Small Growth universe and integrates ESG factors alongside traditional metrics like price-to-earnings (18.35) and price-to-book (3.73) ratios. In recent developments, Janus Henderson completed the acquisition of Victory Park Capital Advisors, a global private credit manager, in October 2024 to enhance private market capabilities, and earlier formed a strategic partnership with NBK Wealth in May 2024 to establish an emerging markets private capital division, reflecting the parent's broader expansion in alternatives amid robust client demand.
