Chinese data values are shown as a marker here so this page stays in English; the /zh page shows them verbatim.

Provenance

These columns are returned alongside the data and record where the row came from. They are provenance, not the dataset's subject matter, so they are listed here rather than in the field table.

Notes & limitations

  • period_semantics=entity_attribute: one quarterly-refreshed row per company, not a daily observation series. The fact date is the period it belongs to, not the disclosure date — align a backtest to the announcement date separately.
