Methodology
Part of the Bagonomics daily editorial rotation — a 14-day cycle of daily research pieces. Each day's slot is selected from the rotation by day-of-year so the same calendar date always lands on the same topic. Data is frozen at publication; live numbers are visible on the linked entity pages. The values, composition, and methodology references above are pulled live from the indexes / index_values / index_compositions / index_methodology_versions tables. The deep-dive is regenerated whenever the rotation lands on this index — composition snapshots therefore reflect the basket as-of the publication date.
