Home Indexes ESI Ethibel Indexes Methodology

Ethibel method of calculating indexes Index committee The Board of Directors of Forum Ethibel assumes the responsibilities of the Index Committee. It is responsible for the index policy, its construction and relationship with the index providers. Eligibility Ethibel uses two main criteria to judge the eligibility of an organisation: sustainability performance always precedes index construction as a criterion. Only the organisations that are included in the Ethibel Investment Register are eligible for inclusion. Ethibel indexes represent a sub-section of the Ethibel Register.   Sector representation Not all sectors are represented with a consideration identical to that of DJStoxx 1800. The goal is to select, for each sector, the most liquid shares meeting Ethibel’s own methodological criteria. Stocks with limited float may be included if they are actively traded, suitably liquid and if the market is large enough. Investable Weight Factor (IWF) or Float Shares Revisions to organisations’ IWFs are done every year by IEM-Finance in order to avoid frequent rebalancing by fund managers. IWF changes greater than or equal to 5% will be implemented as soon as reasonably possible when they result from a major corporate action (privatisation, merger, positioning, etc.).   Index rebalancing Bi-annual index rebalancing includes all share updates and revisions to the index portfolio.
