## How this page is built

Sources: IDX disclosures and ownership filings, the issuer's shareholder register and monthly composition reports, and IDX end-of-day prices. Every row links to the document it came from.

Ownership figures are read from PDFs automatically. A filing whose extraction is pending or below 70% confidence is left out rather than shown as fact.

Not on this page: running trades, broker flow, orderbook depth and intraday prices. Those are in the signed-in terminal.

Research data, not investment advice.
