About MFBFX

MFS Corporate Bond Fund Class A is an open-end mutual fund specializing in investment-grade and select high-yield corporate debt securities. Its primary objective is to generate a total return with strong emphasis on providing current income, while also considering opportunities for capital appreciation. The fund is managed by an experienced team employing both fundamental and quantitative research, focusing on credit quality rather than interest rate sensitivity to identify bonds with solid or improving fundamentals. Typically, it invests at least 80% of its net assets in corporate debt instruments, but may also allocate assets to U.S. government and select foreign securities to enhance diversification. The fund’s portfolio is well diversified across hundreds of issuers and sectors, with an average effective duration of approximately 6.6 years, balancing income generation with moderate interest rate risk. Monthly income distribution and a large asset base underscore its role as a core fixed income holding for investors seeking stability and consistent income within the broader credit markets. Established in 1974, the MFS Corporate Bond Fund Class A plays a significant role in the fixed income landscape for individual and institutional investors alike.
