Permanent monthly editions and monthly readings.

Each monthly edition includes the overall Index reading, industry rankings, the Change-Response Gap and the evidence behind the scores. Monthly tracking began in May 2026.

Every edition is scored under the current methodology, so readings are comparable month to month. The June reading was published with the July 7 release.
