These issuers are in such fields as computer systems and software, networking and telecommunications, internet, business services, and electronics. MFS normally invests the funds assets primarily 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 to any particular investment style. MFS may invest the funds assets in the stocks of companies it believes to have above average earnings growth potential compared to other companies (growth companies) or the stocks of companies it believes are undervalued compared to their perceived worth (value companies). However, companies that benefit from technological advancements and improvements often are growth companies. MFS may invest the funds assets in securities of companies of any size. MFS may invest the funds assets in foreign securities. The fund is a non-diversified fund. This means that MFS may invest a significant percentage of the funds assets in a single issuer or a small number of issuers. MFS may enter into short sales. MFS uses an active bottom-up investment approach to buying and selling investments for the fund. Investments are selected primarily based on fundamental analysis of individual issuers. Quantitative screening tools that systematically evaluate issuers may also be considered. For purposes of the fund's 80% policy, net assets include the amount of any borrowings for investment purposes. Show less
