The iSTOXX Ang Research Enhanced Index Family is designed to deliver enhanced exposure to well-established equity style factors while closely tracking the risk characteristics of its parent benchmark. Single-factor indices focus on their respective factor, while the multi-factor index applies a dynamic approach in which factor weights are adjusted over time based on model-driven signals that assess market conditions, relative factor performance, and factor exposure trends to determine the combined factor allocation. Constituents are drawn from the STOXX US Universal Small Cap Index and weighted using an optimization framework that seeks to maximize exposure to predefined factor scores—Momentum, Quality, Enhanced Value, and Cyclical Value—subject to constraints on tracking error, sector and industry exposure, liquidity, diversification, and turnover.
