Source priority
Sources we prefer
- SEC filings for formal identity, business descriptions, risks and company disclosures.
- Company and investor-relations websites for products, leadership, history and official announcements.
- Government and regulatory agencies for enforcement, litigation, licenses and regulatory events.
- Stock exchanges for listing status and ticker information.
- Reliable news organizations for context and timelines around important events.
- Industry associations and authoritative databases for classifications and technical definitions.
How sources appear
Company pages include a review date and a numbered reading list. Significant historical events and disputed facts should point to a direct source wherever possible. Links are selected for evidentiary value, not commercial relationships.
Time matters
A fact can be correct for one year and wrong later. Employee counts, executives, headquarters, product availability and company status should include a date or review context when it affects meaning.
