C000022037 Investment Objective and Strategy
SA MFS Total Return Portfolio describes its objective and strategy as follows, from its latest prospectus filed with the SEC by Sunamerica Series Trust.
Investment objective
The Portfolios investment goals are reasonable current income, long term capital growth and conservation of capital.
Principal investment strategy
The Portfolio attempts to achieve its investment goal by investing in a combination of equity and fixed income securities. Under normal market conditions, the Portfolio will generally invest approximately 60% of its assets in equity securities and approximately 40% of its assets in debt instruments. These weightings do not reflect the Portfolios cash balance and can vary over time due to market movement and cash flows. The Portfolios investments in fixed income securities may include, but are not limited to, corporate bonds, U.S. Government securities, mortgage- and asset-backed securities and foreign government securities. The Portfolio may also purchase and sell debt instruments on a when-issued, delayed delivery, or forward commitment basis where payment and delivery take place at a future settlement date, including mortgage-backed securities purchased or sold in the to be announced (TBA) market.
Generally, substantially all of the Portfolios investments in debt instruments are investment grade quality debt instruments. The Portfolio may invest in foreign securities (up to 25% of net assets). Of the Portfolios investments in equity securities, the subadviser focuses on investing in the stocks of companies that it believes are undervalued compared to their perceived worth (value companies). Value companies tend to have stock prices that are low relative to their earnings, dividends, assets, or other financial measures. The subadviser normally invests a portion of the Portfolios assets in income-producing equity securities. While the Portfolio may invest the equity portion of its assets in companies of any size, the Portfolio primarily invests in companies with large capitalizations.
The subadviser uses an active bottom-up investment approach to buying and selling investments for the Portfolio. Investments are selected primarily based on fundamental analysis of individual issuers and/or instruments in light of the issuers financial condition and market, economic, political, and regulatory conditions. Factors considered for equity securities may include analysis of an issuers earnings, cash flows, competitive position, and management ability. Factors considered for debt instruments may include the instruments credit quality, collateral characteristics, and indenture provisions, and the issuers management ability, capital structure, leverage, and ability to meet its current obligations. The subadviser may also consider environmental, social, and governance (ESG) factors in its fundamental investment analysis where MFS believes such factors could materially impact the economic value of an issuer.
ESG factors considered may include, but are not limited to, climate change, resource depletion, an issuers governance structure and practices, data protection and privacy issues, and diversity and labor practices. Quantitative screening tools that systematically evaluate the valuation, price and earnings momentum, earnings quality, and other factors of the issuer of an equity security or the structure of a debt instrument may also be considered.
