Janus Henderson Research Fund Class R (JRARX) is an open-end mutual fund managed by Janus Henderson Investors that seeks long-term growth of capital by investing primarily in common stocks selected for their growth potential, including companies of any market capitalization with a focus on large-cap growth; it emphasizes a "pure stock picking" approach leveraging best ideas from global sector research teams, resulting in heavy allocations to technology (52.10%), communication services (14.37%), and consumer cyclical sectors (10.95%), with top holdings such as NVIDIA Corp (15.16%), Microsoft Corp (12.57%), and Apple Inc (6.58%). The fund aligns sector weights closely with its benchmark to minimize macro risks while prioritizing bottom-up fundamental analysis for stock selection within sectors. Launched on January 27, 2017, as a U.S.-domiciled large growth fund available primarily to U.S. investors with a minimum initial investment of $2,500 and a net expense ratio of 1.32%, it forms part of Janus Henderson Investors' broader equity offerings.
Janus Henderson Investors, the fund's manager, traces its roots to Janus Capital Management (founded 1969 in Denver, Colorado) and Henderson Global Investors (origins 1934 in London), merging in 2017 to create a global asset manager headquartered in London with significant U.S. operations in Denver; the firm provides active equity, fixed income, multi-asset, ETF, and alternative investment strategies to individual, advisor, and institutional clients worldwide.
Recent developments at Janus Henderson include the October 2024 acquisition of Victory Park Capital Advisors for expanded private credit capabilities; the September 2024 formation of Janus Henderson Emerging Markets Private Investments Ltd following the acquisition of NBK Capital Partners for emerging markets private capital; the 2024 acquisition of Tabula Investment Management to bolster European ETFs; the June 2025 strategic partnership with Guardian Life Insurance Company to manage a $45 billion investment-grade fixed income portfolio, co-develop multi-asset model portfolios, and launch new ETFs with seed capital; and a 2025 partnership involving Victory Park Capital and CNO Financial Group. These moves reflect ongoing diversification into private markets, alternatives, and institutional mandates amid record assets under management growth. The Research Fund itself maintains portfolio managers John Jordan and Joshua Cummings, appointed January 26, 2024.
