Methodology
- Rows are open-market purchases (code P) and sales (code S) of non-derivative securities from processed Form 4 filings, including rows still awaiting price enrichment, the same rows the screener lists for this sector, side and date range.
- Windows use filing dates in UTC, not trade dates. A 30-day window covers 30 calendar dates ending today; the prior period is the 30 dates before it.
- Sector membership groups each issuer's current SEC SIC code (catalog sec-sic-2026-11-01-v1), not GICS. Issuers with missing or conflicting SIC codes are listed under Unclassified.
- Companies are issuer CIKs aggregated over the whole period and ordered by purchase plus sale dollars, then CIK. A ticker links to its stock page only when company records tie that ticker to the same CIK.
- Cluster companies had at least one purchase in the period carrying the cluster-buy signal. Purchases and sales are listed newest filing first.
- Dollar values are disclosed transaction values; rows without a disclosed value count as transactions but add no dollars.
- Pages keep the period of the first page. Filings processed while you page through can shift later pages.
