About MIACX

MFS Inflation-Adjusted Bond Fund Class C is a mutual fund designed to provide a total return that outpaces inflation over the long term, with an emphasis on generating current income while also considering capital appreciation. The fund primarily invests in inflation-protected U.S. Treasury securities, such as Treasury Inflation-Protected Securities (TIPS), as well as securities issued by U.S. government agencies and select other entities. By holding these inflation-indexed bonds, the fund aims to help investors preserve purchasing power during periods of rising prices. Active portfolio management is employed to enhance returns through duration and yield curve adjustments. MFS Inflation-Adjusted Bond Fund Class C is notable for its focus on fixed-income investments, allocating the vast majority of its assets to bonds, with minimal exposure to equities or foreign bonds. This fund serves a key role for investors seeking protection from inflation’s erosive effects on fixed-income portfolios and is typically used as part of a diversified long-term investment strategy in the context of retirement or capital preservation goals. The fund began operations in 2004 and is benchmarked against the Bloomberg U.S. Treasury Inflation Protected Securities Index, reflecting its commitment to inflation protection within the U.S. bond market.
