For nearly a century, MFS has lined up their active investment approach with a sole purpose: To create long-term value responsibly.

That approach thrives on:

Global collaboration. Integrated global research.

MFS believes the collective expertise of their teams brings them to better investment decisions through:

1. Engagement

  • With the companies they own to understand what could influence their sustainable value
  • Using their voting power to influence issues that matter

  • This helps to build conviction in their investment ideas

3. Integrated research

  • Through a global platform that allows them to develop local market perspectives
  • Drives information sharing across sectors, geographies and asset classes

Actively manage risk: Have conviction in the businesses you own. Focus on the downside.

MFS navigates risk through a process that includes:

1. A risk-aware culture

  • Risk management is a shared responsibility and is central to decision making

2. Understanding material risks

  • They factor environmental, social, or governance (ESG) issues into their research
  • This helps them to understand and ease any risks to sustainable long-term value

Long-term discipline. Develop investment talent.

Thinking long-term has always been part of MFS' heritage because they believe it helps pursue the outcomes investors need.

Long-term discipline takes:

1. Conviction and longer time horizons

  • This is made possible by robust research and the confidence to let their investment thesis play out

2. Sustainable investing

  • Where they favour environmental, social, or governance (ESG) integration and engagement over a separate outcome

3. Continuity & succession planning

  • To develop talent and plan for their next generations of leadership and investment teams
