The funds investment objective is to seek capital appreciation.
The fund invests primarily in foreign equity securities, emphasizing small- to medium-capitalization growth companies selected through bottom-up fundamental analysis of individual issuers. MFS may invest a significant percentage of assets in a single industry, sector, country, or region, concentrating exposure in ways that could cause the fund to diverge materially from broader foreign equity markets.

How it has done
MIDAX share class · total returns with dividends reinvested
Volatility over the last 12 months: 14.89%. Past returns are a record, not a forecast.
Jun 2026 has been filed since the trailing figures were struck, so it is not in the table above or the curve — every figure here shares one cut-off, which is what makes them comparable with other funds.
