Dataset
ProReturn Index (daily)
Daily total-return index levels — per row: trade date, market, index id, index name, return-index value, and source tags; sourced from the TWSE.
What this data is
Each row is one index's return level for one day, carrying trade_date / market / index_id / index_name / return_index_value / source_name / source_url (trade date, market, index id, index name, return-index value, and source tags). Sourced from the TWSE, graded derived (computed from official data). The backend /v2/datasets meta exposes only grade / tier / point-in-time and no coverage window, so none is stated here.
Use cases
- Compute true long-run returns from the total-return index.
- Compare price vs return index to isolate the dividend contribution.
- Use as the official return benchmark for passive-strategy performance.
Why it matters for stock analysis
A price index excludes dividends and understates long-run returns; this dataset serves the official total-return index daily, no manual dividend add-back.
