About MFBBX

MFS Corporate Bond Fund B is an actively managed mutual fund focused on providing total return, emphasizing current income while also considering capital appreciation. The fund primarily invests in U.S. dollar-denominated corporate bonds and related debt securities, with a strong focus on credit analysis rather than duration management as its core value-adding strategy. The portfolio is constructed through a blend of fundamental and quantitative analysis, incorporating both micro and macroeconomic factors, and aims to hold corporate bonds that exhibit solid or improving financial fundamentals. While the majority of assets are allocated to investment-grade bonds, there is some exposure to non-investment grade debt as well. The fund utilizes sophisticated risk management techniques and maintains both long and short positions, including positions in U.S. Treasury futures and large-cap corporate issuers across sectors such as financials, industrials, and manufacturing. The benchmark for performance comparison is the Bloomberg U.S. Credit Bond Index, which tracks the market of publicly issued U.S. corporate debt. Managed by MFS Investment Management since 1974, the fund plays a role in providing credit market exposure and income generation within a diversified investment portfolio.
