Index Description

STOXX single and multi-factor indices aim to harvest the risk premia of several academically validated style factors – Value, Momentum, Quality, Size and Low Risk. At the same time the rules ensure tradability and diversification as well as limit untargeted systematic exposures. STOXX uses Axioma's risk model and optimizer to construct the factor indices. The STOXX ESG-X single and multi-factor indices are based on the respective STOXX ESG-X country or regional benchmark indices. This index applies screens in alignment with the ESMA guidelines on funds’ names using ESG or sustainability-related terms, which include controversial weapons, Tobacco, Coal (>1%), Oil fuels (>10%), Gaseous fuels (>50%/ Power generation), UNGC principles / OECD guidelines.Per the ESMA guidelines on funds’ names using ESG or sustainability-related terms, this index meets an 80% threshold linked to the proportion of investments used to meet environmental or social characteristic or sustainable investment objectives in accordance with the binding elements of the investment strategy. Index Guides, Benchmark statement, and other reports are available under the Data tab.
