Russell® 1000 Value Index Reclassification
How We Invest
In 1924, MFS launched the first open-end mutual fund in the US, and in 1932 we built one of the industry's first in-house research departments. Today, we have nearly a century of active management expertise and invest around the globe.
Our focus remains the same — fundamental research that strives to spot long-term opportunities and indentify risks. We would rather find good performance that lasts than great performance that doesn't.
