Under normal circumstances, the Fund will invest at least 80 percent of its net assets (plus the amount of any borrowings for investment purposes) in equity and equity-related securities (such as convertible bonds, convertible preferred stock, depositary receipts, warrants and rights) issued by large U.S. companies. The Fund seeks to provide long-term capital appreciation by investing primarily in U.S. common stocks, while aiming to experience lower volatility compared to the broad U.S. large cap equity market. SIMC uses a quantitative-based, active stock selection investment process to construct the Fund's portfolio, utilizing a combination of factor scoring model, risk model and optimization. The factor scoring model evaluates all of the securities in the investment universe of U.S. large-capitalization stocks based on measures of Value, Momentum, Quality and Low Volatility factor families.
