Data sources

Constituent holdings and portfolio weights come from the fund manager's published holdings files. We retain local listing and trading-venue information so each security is measured in its own market.

Price observations and FX rates are sourced from market-data providers. Coverage and timing vary by exchange, instrument and provider; prices may be delayed and are not intended for trading or settlement.

The figures on this site are analytical estimates, not official index calculations. They can differ from an issuer's published return because of pricing time, holdings changes, fees, corporate actions and other index methodology details.
