About MIAJX
MFS Inflation-Adjusted Bond Fund Class R4 is a mutual fund designed to provide total returns that outpace the rate of inflation over the long term, with a primary emphasis on generating current income and a secondary focus on capital appreciation.

As part of its investment strategy, the fund actively manages duration and the yield curve to optimize returns in varying market environments. With net assets of over $1.4 billion as of June 2025, the fund is benchmarked against the Bloomberg U.S. Treasury Inflation Protected Securities Index, which serves as a standard measure for inflation-protected bond performance.
