Eaton Vance Strategic Income Fund Class I (ESIIX) is a multisector bond mutual fund that seeks total return through a flexible, fund-of-funds investment strategy, allocating assets primarily to registered investment companies managed by Eaton Vance and its affiliates; these include the Global Opportunities Portfolio, Global Macro Absolute Return Advantage Portfolio, High Income Opportunities Portfolio, Eaton Vance Emerging Markets Debt Opportunities Fund, Senior Debt Portfolio, and Emerging Markets Local Income Portfolio, among others, providing broad exposure to fixed-income sectors such as U.S. and non-U.S. bonds (58.90% and 29.25% of assets, respectively), mortgage-backed securities, floating-rate loans, high-yield corporate bonds, emerging markets debt, absolute return strategies, currency instruments, and cash equivalents. The fund offers sweeping exposure across global fixed-income markets with an emphasis on risk-adjusted performance and diversification benefits from underrepresented asset classes like non-investment-grade bonds and foreign bonds; it maintains an average duration of approximately 4.46 years, a low correlation of 0.40 to the Bloomberg U.S. Aggregate Bond Index over 10 years, and total net assets of $12.6 billion as of September 30, 2025. Eaton Vance, the fund's manager and part of Morgan Stanley Investment Management following Morgan Stanley's $7 billion acquisition completed in 2021, was originally founded in 1924 with headquarters in Boston, Massachusetts, and operates globally with a focus on institutional and high-net-worth investors requiring a minimum initial investment of $1,000,000 for Class I shares. In a significant recent change effective January 16, 2024, the fund renamed from Eaton Vance Short Duration Strategic Income Fund to Eaton Vance Strategic Income Fund and amended its principal strategy to remove the prior limitation on average duration to 3.5 years or less under normal market conditions, enabling broader flexibility in pursuit of total return.
