C000177075 Investment Objective and Strategy
SA Small Cap Index 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 goal is investment results that correspond with the performance of the Russell 2000 Index.
Principal investment strategy
The Portfolio seeks to provide investment results that correspond with the performance of the Russell 2000 Index (the Index). The Index measures the performance of small-capitalization companies in the United States. It is a subset of the Russell 3000 Index, which comprises the 3,000 largest U.S. companies based on total market capitalization. The subadviser primarily seeks to achieve the Portfolios objective by investing in all or substantially all of the stocks included in the Index, a strategy known as replication. The subadviser may, however, utilize an optimization strategy in circumstances in which replication is difficult or impossible, such as if the Portfolio has low asset levels and cannot replicate, to reduce trading costs or to gain exposure to securities that the Portfolio cannot access directly.
The goal of optimization is to select stocks which ensure that characteristics such as industry weightings, average market capitalizations and fundamental characteristics ( e.g. , price-to-book, price-to-earnings, debt-to-asset ratios and dividend yields) closely approximate those of the Index. Stocks not in the Index may be held before or after changes in the composition of the Index or if they have characteristics similar to stocks in the Index. Under normal circumstances, the Portfolio invests substantially all, but at least 80%, of its net assets in securities included in the Index or in securities that the subadviser determines have economic characteristics that are comparable to the economic characteristics of securities included in the Index, including derivatives, such as contracts for difference.
The Portfolio will not concentrate, except to approximately the same extent as the Index may concentrate, in the securities of any industry. It is not anticipated, however, that the Portfolio will, under normal circumstances, be concentrated in the securities of any industry. Because the Portfolio will generally not hold all of the stocks included in the Index, and because the Portfolio has expenses and the Index does not, the Portfolio will not duplicate the Indexs performance precisely. However, the subadviser believes there should be a close correlation between the Portfolios performance and that of the Index in both rising and falling markets.
