The fund employs a disciplined, bottom-up investment approach that combines MFS’ proprietary fundamental research with quantitative insights, the firm said in a statement. It seeks to generate the majority of alpha through security selection while aiming to minimise benchmark-relative volatility and unintended exposures across sectors and industries.

This launch marks the second target tracking error strategy in the Meridian Fund range that uses MFS’ blended research approach, following the introduction of the MFS Meridian Funds® – Blended Research European Equity Fund in 2016.

At the heart of this strategy is a process that brings together the views of fundamental equity analysts and quantitative models, each assessing companies across regions and sectors. These views are individually converted into scores and then combined to form a single blended research score. The portfolio is built to maximise exposure to that score by emphasising stock-specific opportunities while limiting broader market risks such as beta, sector, size and style. This approach is supported by MFS’ Global Investment Platform, which brings together eight global sector teams and more than 300 quantitative, equity, and fixed income investment professionals worldwide.

“We believe some of the strongest investment ideas emerge when both experienced analysts and powerful data models point in the same direction," said Matt Weisser, managing director – Europe. “Quantitative research gives us a systematic view of a company’s fundamentals and valuation, while fundamental research adds the forward-looking judgment and context that numbers alone cannot provide. For us, the real opportunity is where the two meet.”

The fund’s objective is capital appreciation through investing primarily in US equity securities, with the goal of outperforming the S&P 500 Index over a full market cycle. The aim is to manage the portfolio with a controlled tracking error. The fund will typically hold 80 to 150 securities.

The fund is led by portfolio manager Matthew Krummel, alongside Nate Bryant, Jonathan Sage, Jenney Zhang and Jed Stocks. The investment team brings more than 20 years of industry experience and long tenure within the firm. Jeffrey Morrison and George Fontaine serve as institutional portfolio managers, supporting client communications around investment policy, strategy and positioning for the blended research strategies.

“In today’s environment of heightened market concentration and macro uncertainty, investors are increasingly seeking diversified and risk-aware access to US equities,” Weisser said. Our blended research approach combines quantitative insights with fundamental expertise within a disciplined framework, aiming to deliver consistent alpha across market cycles. We believe this strategy offers clients a balanced way to access the depth and innovation of the US market while maintaining a strong focus on risk management and long-term outcomes."

As of 31 March 2026, MFS had about $622.2 billion in assets under management.
