When the market's own view on sustainability meets transparent index construction
Fair Cost Index (FCI) and ValueCo have launched the FCI VALUECO ESG CONSENSUS family: four equity indices covering the United States, Europe, the Eurozone and World Developed markets, live since October 1, 2026.
ValueCo is a Paris-based fintech led by its cofounders, Mariem Mhadhbi and Mathieu Joubrel. Rather than issuing yet another ESG rating, it aggregates the proprietary ESG assessments of 50+ institutional investors, representing more than $9 trillion in assets, into an objective and anonymized market consensus: a clear view of how investors actually perceive a company's sustainability profile.
The partnership gives this consensus a concrete use. FCI's APT-based optimizer integrates it into index construction, with a clear target: improving the average ESG score of the underlying market by 20%, while preserving a faithful, style-neutral representation of the universe. Monthly rebalancing is capped at 1% turnover, and, like all FCI indices, the family FCI VALUECO ESG CONSENSUS comes with a transparent methodology, fair fees and no usage restrictions.
The FCI VALUECO ESG CONSENSUS now comprises the following indices:
