About MIAAX

The MFS Inflation-Adjusted Bond Fund Class A is a mutual fund that primarily invests in inflation-protected, investment-grade debt securities issued by the U.S. Treasury and other U.S. government-related entities. Its primary objective is to achieve a total return that exceeds the rate of inflation over the long term, offering both current income and the potential for modest capital appreciation. This fund targets investors who are seeking to preserve purchasing power in environments where inflation could erode fixed-income returns, making it particularly relevant for long-term savers and conservative portfolios. The fund manages risk and return through active duration and yield curve strategies, with a diversified portfolio concentrated in U.S. government securities. Notable features include a quarterly dividend payout, a competitive distribution yield, and a history dating back to 2003. The fund is benchmarked to the Bloomberg U.S. Treasury Inflation Protected Securities Index, underscoring its focus on inflation mitigation within the broader fixed-income landscape. Overall, the MFS Inflation-Adjusted Bond Fund Class A plays a specialized role, offering inflation-sensitive fixed-income exposure that complements traditional bond allocations.
