Janus Henderson U.S. Sustainable Equity ETF (SSPX) is an actively managed exchange-traded fund that seeks long-term growth of capital by investing primarily in U.S. large-cap companies aligned with environmental and social sustainability themes, including resource efficiency, healthier and cleaner living, sustainable healthcare, and return on human capital; the fund may also allocate up to 30% of assets to mid- and small-cap companies, collective investment schemes, or cash equivalents that support positive environmental or social change or enhance quality of life without conflicting with core themes. Launched on September 8, 2021, and managed by Hamish Chamberlayne and Aaron Scully, SSPX targets institutional and retail investors focused on sustainable equity strategies within the large growth segment, with assets under management of approximately $8-10 million as of late 2025 and a net expense ratio of 0.55%. The ETF trades on NYSE Arca and emphasizes companies deriving significant revenue from products and services contributing to sustainability challenges like climate change, population growth, and resource constraints.
In July 2025, Janus Henderson announced the closure and liquidation of SSPX following a routine review of its exchange-traded product lineup to better align offerings with client needs; the fund ceased accepting creation orders after October 9, 2025, halted trading on October 10, 2025, and distributed liquidation proceeds around October 16, 2025. This decision reflects ongoing strategic optimization amid low assets and performance considerations, consistent with broader firm developments such as acquisitions of Victory Park Capital Advisors in October 2024 for private credit expansion and NBK Capital Partners in September 2024 for emerging markets private investments, alongside a joint venture with Guardian in June 2025 for fixed income management. SSPX operates as part of Janus Henderson Group plc, a London-headquartered global asset manager with over $373 billion in assets under management as of March 2025, offices in 25 cities worldwide, and a focus on active sustainable and thematic investment strategies.
