About MRBGX
MFS Total Return Bond Fund R1 is an actively managed mutual fund specializing in U.S. dollar-denominated fixed-income investments. Its primary objective is to achieve a total return with a strong emphasis on current income, while also considering the potential for capital appreciation.

By maintaining a core-plus strategy, the fund has flexibility to allocate across multiple bond sectors—such as high-yield, emerging market debt, and non-U.S. currency exposure—providing opportunities for yield and diversification beyond traditional core bonds. Managed through a collaborative approach combining macroeconomic assessment, security selection, and yield curve positioning, the fund aims to optimize risk-adjusted returns within the intermediate-term bond space. MFS Total Return Bond Fund R1 plays a key role for investors seeking diversified exposure to the U.S. fixed-income market, balancing income generation with a disciplined risk management framework.
