Janus Henderson Short Duration Flexible Bond Fund (JSHSX) is an open-end mutual fund managed by Janus Henderson Investors that seeks a high level of current income consistent with the preservation of capital. The fund normally invests at least 80% of its net assets in short- and intermediate-term fixed-income securities, including U.S. Treasury notes and bonds, corporate bonds, asset-backed securities, commercial mortgage-backed securities, agency mortgage-backed securities, and non-U.S. bonds; it maintains a diversified portfolio with top holdings such as United States Treasury Notes (various yields including 3.75%, 3.625%, and 4.25%) representing approximately 16.40% of assets, alongside cash equivalents like Janus Henderson Cash Liquidity Fund LLC. Primarily targeting U.S. investors in the short-term bond category with mid credit quality and limited interest-rate sensitivity, the fund operates from Denver, Colorado, where Janus Henderson maintains a key office alongside its global head office in London, United Kingdom, and serves clients through daily pricing with a net expense ratio of 0.90% and a minimum initial investment of $2,500. Launched on July 6, 2009, as a Class S share, the fund is comanaged by Michael Keough (since December 3, 2019) and Greg Wilensky (since February 1, 2020), employing a bottom-up, fundamentally driven process with integrated equity-fixed income research and proprietary risk management via the Quantum Global system. In recent developments, Janus Henderson bolstered its private credit capabilities through the acquisition of a majority stake in Victory Park Capital in 2024, enhancing its securitized assets under management exceeding $36 billion globally; the firm also announced closures of certain ETFs like the International Sustainable Equity ETF in 2024 and U.S. Sustainable Equity ETF in 2025 as part of ongoing product lineup reviews, while in December 2025, Janus Henderson Group plc itself was acquired by Trian Fund Management and General Catalyst for $7.4 billion. As of late 2025, the fund manages total net assets of approximately $735 million, with about 91% in U.S. bonds, 7% in non-U.S. bonds, and 2% in cash.
