Fund profile

As filed in the prospectus · 2026 Q1

The funds investment objective is to seek capital appreciation.

Strategy · summarised

The fund invests at least 80% of assets in stocks of growth companies, which MFS identifies through inclusion in growth indices, third-party classification, or characteristics such as above-average historical or projected earnings growth relative to the market. The manager employs a bottom-up fundamental analysis of individual issuers, supported by quantitative screening tools. The fund may invest significantly in a single issuer or small number of issuers, and may concentrate a substantial portion of assets in one industry or sector.
