What this dataset contains
The dataset is a single train split of 238,159 rows indexing SEC EDGAR submissions alongside descriptive attributes about the filing entity. Each row corresponds to one filing record and links identifiers such as kl3m_id, cik, accessionNumber, and form with issuer-level fields like name, ein, ownerOrg, and exchanges. The schema suggests broad coverage of registered filers, with fields such as sic, sicDescription, stateOfIncorporation, and formerNames supporting industry and corporate-history analysis.
Structure and fields
Records are stored as Parquet with a mix of string fields and a single int64 size column. Filing-level keys include kl3m_id, cik, filingDate, form, core_type, accessionNumber, reportDate, acceptanceDateTime, fileNumber, and filmNumber. Issuer-level descriptors include name, ein, entityType, ownerOrg, description, website, investorWebsite, phone, tickers, exchanges, sic, sicDescription, category, fiscalYearEnd, stateOfIncorporation, and formerNames, while primaryDocDescription is nullable and items is stored as a string.
How analysts use it
Analysts can use the index to map filings to issuers via cik, accessionNumber, and ticker symbols, then join the structured metadata to filing documents for downstream text or fundamental analysis. Fields such as sic, sicDescription, fiscalYearEnd, and stateOfIncorporation enable sector and domicile screens, while acceptanceDateTime and filingDate support event-study or filing-lag analyses. Coverage of forms beyond 10-K in the schema (e.g., core_type and form values shown in samples) indicates the file can also serve as a broader EDGAR submission inventory for compliance and back-office workflows.
