Janus Henderson Multi-Sector Income Fund (JMTNX) is an open-end mutual fund that seeks high current income with a secondary focus on capital appreciation through a multi-sector fixed income strategy. Launched on February 28, 2014, and managed by Janus Henderson Investors, headquartered at 151 Detroit Street in Denver, Colorado, the fund primarily invests under normal circumstances in a diversified portfolio of U.S. and non-U.S. debt securities, including high-yield (below-investment-grade) bonds, investment-grade corporate bonds, asset-backed securities, mortgage-backed securities such as those issued by the Federal National Mortgage Association, government notes, commercial loans, and emerging markets debt via holdings like the Janus Henderson Emerging Markets Debt Hard Currency ETF; it typically allocates 35% to 65% to below-investment-grade bonds while employing dynamic risk budgeting, bottom-up fundamental analysis, and a high-conviction best-ideas approach to identify risk-adjusted opportunities across fixed income sectors with lower volatility than a dedicated high-yield strategy. The fund maintains a strategic asset allocation that outperforms traditional benchmarks like the Bloomberg U.S. Aggregate Bond Index, with allocations heavily weighted toward U.S. bonds (approximately 82%), non-U.S. bonds (12%), and cash equivalents, serving institutional investors with a minimum initial investment of $1 million and available primarily in the United States. In recent developments, the fund benefited from a contractual reduction in the management fee breakpoint schedule effective October 28, 2024, alongside quarterly performance outperformance in Q3 2025 (2.47% return versus the benchmark); at the parent company level, Janus Henderson expanded through acquisitions including Tabula Investment Management for European active ETFs, NBK Capital Partners for emerging market private investments, and Victory Park Capital for global private credit in 2024, as well as a joint venture with Privacore Capital and a strategic partnership with Guardian to bolster fixed income and institutional capabilities.
