Massachusetts Investors Trust describes its objective and strategy as follows, from its latest prospectus filed with the SEC by Massachusetts Investors Trust.
Investment objective
The funds investment objective is to seek capital appreciation.
Principal investment strategy
MFS (Massachusetts Financial Services Company, the fund's investment adviser) 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 by 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), in the stocks of companies it believes are undervalued compared to their perceived worth (value companies), or in a combination of growth and value companies. While MFS may invest the funds assets in securities of companies of any size, MFS primarily invests in securities of companies with large capitalizations.
MFS may invest the funds assets in foreign securities. MFS normally invests the fund's assets across different industries and sectors, but MFS may invest a significant percentage of the fund's assets in issuers in a single industry or sector. 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.
