MFS

Global asset manager of mutual funds

Overview

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.

MFS launches European fixed income fund with shorter maturity profile

MFS Investment Management has launched the MFS Meridian Funds - EuroCredit Short Term Bond Fund, an actively managed European fixed income fund with a shorter maturity profile, holding positions that mature in less than five years. The fund primarily invests in investment grade corporate and quasi-sovereign debt instruments denominated in or hedged to euros. It aims to outperform the Bloomberg Euro Aggregate Corporate 1-3 Year Index over a full market cycle. The launch expands MFS's European fixed income range and complements the MFS Meridian Funds - Euro Credit fund, launched in early 2019. The new fund is domiciled and regulated in Luxembourg with a sicav structure and is registered for sale in 15 countries. The strategy is co-managed by portfolio managers Pilar Gómez-Bravo and Andy Li, whilst institutional portfolio manager Owen Murfin participates in investment strategy analysis and discussions.

Diversifying portfolios: MFS launches 2 new etfs.

Diversifying portfolios: MFS launches 2 new etfs. On June 4, MFS expanded its ETF suite with the launch of the MFS Blended Research Small-Mid Cap ETF (BRSM) and the MFS Active International Value ETF (MIVL). With an expense ratio of 38 basis points, BRSM broadens MFS's actively managed offerings into the small-mid cap market. MIVL primarily invests in value companies across foreign markets and carries an expense ratio of 57 basis points. Capitalizing on market momentum outside large caps. After years of large-cap dominance, small-mid cap equities have regained momentum in 2026. With interest rates returning towards lower levels, the introduction of BRSM coincides with a period of improved performance for small-mid cap companies. Year to date, the Russell 2500 index has delivered returns of approximately 13%, exceeding the roughly 9% return of large-cap indexes like the VettaFi US Equity Large-Cap 500 Index. The fund targets companies and REITs within the market capitalization range of the Russell 2500 Index. BRSM combines active security selection with a portfolio construction process designed to keep overall portfolio characteristics relatively close to the benchmark. BRSM evaluates securities using both fundamental and quantitative research inputs through the firm's blended research methodology. On the fundamental side, companies are evaluated based on factors such as financial condition and the broader industry environment. Quantitative models simultaneously evaluate characteristics including price momentum and earnings trends. These inputs are combined into a single blended rating that serves as the primary basis for portfolio construction. A global approach to value investing. For a better part of the last decade, U.S. equities have substantially outperformed most international markets. This has largely been driven by the growth of a relatively small group of mega-cap technology firms. While that performance has rewarded investors who remained concentrated in U.S. equities, it also widened valuation gaps between U.S. and international markets. However, with international equities showing signs of prolonged outperformance, the disparity is beginning to narrow. MIVL provides exposure to international equities through a value-oriented investment framework. The strategy focuses primarily on non-U.S. equities and may allocate a portion of assets to emerging markets. The fund is not constrained by company size and can invest across the market-capitalization spectrum when attractive opportunities are identified. Rather than tracking a value benchmark, the fund identifies companies believed to be trading below their estimated intrinsic value while maintaining investment across countries, sectors, and regions. Expanding on its actively managed international ETF lineup, MIVL serves as the firm's third venture into the space. Both MIVL and BRSM build upon previous launches such as the MFS Blended Research International Equity ETF (BRIE), which debuted in October last year.
