MassMutual Inflation-Protected and Income Fund Class R4 is a mutual fund designed to provide investors with a high rate of total return, consistent with prudent investment policies. Its primary focus is on investing at least 80% of its assets in inflation-indexed bonds of varying maturities, which are issued by U.S. and non-U.S. governments, their agencies or government-sponsored enterprises, as well as corporations. This approach aims to help protect investors' purchasing power against the erosive effects of inflation, making the fund relevant for those seeking inflation-sensitive income streams. The portfolio is diversified across sectors, and the fund typically maintains a large number of holdings, offering exposure to both domestic and international inflation-linked securities. With a performance and risk profile typical of the inflation-protected bond category, this fund plays a significant role in fixed income strategies for institutional and individual investors who value inflation mitigation within their asset allocation framework. Additionally, the fund pays income monthly and is managed by a team of professionals, with a long-term track record dating back to its inception in 2014.
