RUSC primarily invests in US small-cap stocks through a multi-manager, multi-style framework that combines insights from multiple unaffiliated sub-advisors. These sub-advisors provide model recommendations across investment styles. The manager then aggregates the models in a composite portfolio and applies a quantitative optimization process alongside qualitative assessments. The strategy aims to reflect the most optimal trade-off among risk/return factors, transaction costs, and turnover. Positions focus on exposures like value, growth, momentum, quality size, volatility, and sector positioning, while controlling for turnover, transaction costs, position sizes, and overall portfolio weightings. Investments include common and preferred stocks, partnership interests, and REITs. The fund may use derivatives like futures and forward contracts to manage exposure. Note that some holdings are considered micro-cap companies. Prior to October 1, 2025, the fund traded under the name U.S. Small Cap Equity Active ETF.
