MFS Investment Management has launched MFS Meridian Funds – Blended Research US Core Equity Fund, an actively managed strategy domiciled and regulated in Luxembourg that aims to invest primarily in US equities through quantitative and fundamental analysis.
Fund strategy
The fund’s objective is capital appreciation through investment primarily in US equity securities. MFS stated that the strategy seeks to outperform the S&P 500 Index over a full market cycle while managing a controlled tracking error.
The portfolio will typically hold 80 to 150 securities. MFS mentioned in its risk disclosures that the strategy targets a predicted tracking error of approximately 2% against the index, although it warned that predicted and actual tracking error may differ.
The launch is the second target tracking error strategy in the Meridian Funds range to use the Blended Research approach, after the MFS Meridian Funds – Blended Research European Equity Fund in 2016.
Blended research
MFS stated that the fund uses a bottom-up process combining its proprietary fundamental research with quantitative insights. The company added that the strategy seeks to generate most of its alpha through security selection while limiting benchmark-relative volatility and unintended sector and industry exposures.
Under the process, fundamental equity analysts and quantitative models assess companies across regions and sectors. Their views are converted into scores and combined into a single Blended Research score.
The portfolio is then built to maximise exposure to that score, emphasising stock-specific opportunities while limiting broader risks such as beta, sector, size and style. MFS stated that the approach is supported by its Global Investment Platform, which includes eight global sector teams and more than 300 quantitative, equity and fixed income investment professionals worldwide.
Matt Weisser, managing director for Europe at MFS Investment Management, argued that quantitative research gives a systematic view of company fundamentals and valuation, while fundamental research adds forward-looking judgement and context. Weisser added that, amid heightened market concentration and macro uncertainty, investors were increasingly seeking diversified and risk-aware access to US equities.
The fund is led by portfolio manager Matthew Krummel. MFS stated that the investment team has more than 20 years of industry experience and long tenure within the firm. The fund is structured as a Sicav and registered for sale in 15 countries: Austria, Denmark, Finland, France, Germany, Ireland, Italy, Luxembourg, the Netherlands, Norway, Singapore, Spain, Sweden, Switzerland and the United Kingdom. MFS announced the launch on 18 May 2026.
As of 31 March 2026, MFS reported approximately $622.2bn in assets under management. MFS Meridian Funds are not available for sale in the United States or to US persons.
