About WhichIndex

WhichIndex records who is in each stock index, how much each member weighs, and which indexes each company belongs to. It is an independent reference: every table is built from a published source and says which one, and on which date.

Sources

Member lists come from public fund holdings, exchange pages and index factsheets; market caps from each exchange's daily listings. Each table names its source and date, and every correction is dated in the corrections log.

Data can be incomplete, late or wrong: check the index provider, linked from every index page, before relying on it.
