This index aims to identify U.S. mid-sized company stocks from the broader MSCI USA Mid Cap Index that exhibit strong alignment with four specific investment style factors: value, quality, momentum, and a smaller market capitalization. A key design principle is to ensure that the overall risk level remains similar to that of the parent index. The fund typically commits at least 80% of its total assets to the securities comprising this underlying index, or to other investments whose economic attributes are virtually identical to those index components.
