This refactored IFVI value factor dataset has been supplanted by V2.
This dataset tracked the V2 of the IFVI release that was updated in March 2025. The V2 of the refactored analytical dataset tracking the GVFD was released on August 20th, 2025 and is now available at:
🔗 IFVI Global Value Factors Dataset V2
Please use the V2 dataset for all new projects and analysis.
