| Investment Objective: |
The fund's investment adviser seeks to achieve the fund's objective by actively identifying potential investments based on fundamental and quantitative analysis and then constructing a portfolio from these potential investments while managing various risk factors (e.g., issuer, industry, and sector weightings, market capitalization, and volatility) compared to the Standard & Poor's 500 Stock Index. MFS normally invests at least 80% of the fund's net assets in equity securities. Equity securities include common stocks, depositary receipts, and other securities that represent an ownership interest (or right to acquire an ownership interest) in a company or other issuer. In selecting investments for the fund, MFS is not constrained by any particular investment style. While MFS may invest the fund's assets in securities of companies of any size, MFS primarily invests in securities of companies with large capitalizations. MFS uses an active bottom-up approach to buying and selling investments for the fund. Investments are selected primarily based on blending fundamental and quantitative research. MFS uses fundamental analysis of individual issuers to determine a fundamental rating for an issuer. MFS uses quantitative analysis to determine a quantitative rating for an issuer. |
