Stock market data infrastructure
Stock data sources and provenance
Understand the distinction between SEC and ASX source documents, normalized financial fields, market-data providers, and derived values.
Documentation revised
Source documents and structured fields
The application integrates SEC EDGAR financial and filing data and stored ASX company reports. Filing links identify documents; normalized financial responses identify reporting fields. Retain both when an audit must connect a value with its published context. Document presence and field extraction completeness are separate measures.
Market data and transformations
Price and profile collection uses provider integrations, including yfinance-based collection paths. Inspect returned source and currency_basis labels rather than assuming all observations come directly from an exchange. Daily price history can be adjusted for corporate actions, and ratios or aggregate periods can be calculated from stored inputs.
Attribution has limits
primary_source is a record-level label; sources is optional field-level metadata. Missing attribution stays unknown. These labels do not imply a license grant, universal source agreement, or independent verification of every record. Follow the current terms and consult original documents when investigating discrepancies.
