[capellini]

All data on jkpfactors.com has been updated through December 2025.

What's Updated

• Factor returns (long-minus-short, high-minus-low, theme clusters) for all 153 characteristics
• Portfolio returns (low/middle/high breakpoint portfolios)
• Market returns, including the capped value-weighted excess market return
• Industry returns (GICS and Fama-French 49)
• Size-specific factor returns
• Performance statistics (Sharpe ratios, alphas, information ratios)
• Factors to watch rankings

All 93 countries and regional aggregates (developed, emerging, frontier, world, world ex-US) are included.

Notable Changes

Market returns extended. Market return download files previously ended at December 2023 due to a bug in the data preparation pipeline. They now extend through December 2025, consistent with all other data files.

First update from the Python pipeline. This is the first data update produced entirely by the Python codebase, replacing the legacy SAS/R pipeline.

Expanded downloads. In addition to the data refresh, we've added several new data types for download. See our companion announcement for details.
