The Index, run by run

4 published runs since 13 August 2026, each carrying what it published, what it scored, and the same-constituents level that makes two runs comparable.

Every run so far

What each run published. The same-constituents level beside it is the one to read across runs, because the first moves when a directory joins or leaves.

Every published run of the Index, oldest first, with its level, its same-constituents level and its panel size.

Every run reads whatever was readable that week, so a directory can join or leave without anything in the market changing. That alone moves the published level, which is why the same-constituents series sits beside it. What a constituent change does to the level
