MFS Investment Management is a global asset manager that runs mutual funds and active ETFs for individuals, financial advisors, and institutions. It manages money with an active investment approach, meaning portfolio managers pick securities they believe will outperform over time, and then structure these ideas into mutual funds and active ETFs. The company combines a long history (dating back to 1924 with the creation of the first mutual fund) and a global footprint under Sun Life Financial to offer a diverse set of investment products. Its difference lies in an established track record, collaborative active management, and a broad client base across regions, with about $619.6 billion in assets under management as of May 2025. The goal is to generate long-term value for clients by actively managing portfolios and seeking performance across markets.
