About MRBHX
MFS Total Return Bond Fund Class R3 is an actively managed mutual fund within the intermediate core-plus bond category. Its primary objective is to achieve total return with a strong emphasis on current income, while also considering opportunities for capital appreciation. The fund primarily invests in investment-grade fixed income securities, including U.S. government, corporate, and securitized debt, but it also has the flexibility to allocate assets to non-core sectors such as high-yield bonds, bank loans, emerging-market debt, and non-U.S. currency exposure.
Managed through a collaborative, research-driven approach, the fund’s team integrates macroeconomic insights, detailed security analysis, and quantitative tools to inform portfolio construction, sector allocation, and strategy risk management. This approach seeks to add value via both security selection and active positioning along the duration and yield curve. Benchmarked to the Bloomberg U.S. Aggregate Bond Index, the fund provides investors with diversified exposure to the broader U.S. fixed-income market. MFS Total Return Bond Fund Class R3 is commonly used by investors and retirement plans seeking a balance of income and potential growth from a broad mix of bond assets, supported by the resources and experience of MFS Investment Management.
