Methodology & limitations

Read the cadence before the ranking.

Each fund is its latest accepted, reconciled disclosure from an official fund source. Quarterly regulatory filings are never presented as daily holdings. A selected fund may show verified Japanese companies while other company assets remain unmatched. Current verified-subset values are exact for the accepted mapping state, but the current verified subset can be revised when later official evidence creates a conflict.

Company exposure requires an unambiguous canonical-listing match and a disclosed weight. Cash, collateral, currencies, and derivatives never silently become company exposure.
