About MIAKX

MFS Inflation-Adjusted Bond Fund R6 is a mutual fund designed to provide investors with returns that exceed the long-term rate of inflation, emphasizing current income while also considering capital appreciation. The fund primarily invests in inflation-protected securities—most notably U.S. Treasury Inflation-Protected Securities (TIPS)—as well as similar debt instruments issued by government agencies and select entities. By focusing on these assets, the fund aims to help preserve purchasing power in environments where inflation may erode fixed income returns. Management employs active strategies around duration and yield curve positioning in order to optimize performance relative to its benchmark, the Bloomberg U.S. Treasury Inflation Protected Securities Index. With over 100 holdings and a sizeable asset base, the fund plays a significant role for institutional and individual investors seeking to mitigate inflation risk within their fixed income allocation. Typically, this fund appeals to those seeking inflation resilience in their portfolios, while maintaining exposure to high-quality government-backed securities.
