Company grouping is a reading aid, not a merger of transactions or uncertain ownership ratios. Value sorting uses each company’s usable total; expand to see every matching row.

Reading these disclosures

Form 4 disclosures are not real-time trade alerts. An unchecked 10b5-1 indicator does not establish discretionary timing. Direct and indirect holdings remain separate; unresolved amendments stay under review.

Filed prices are not all independently market-verified. Source: SEC EDGAR; the update target is every 15 minutes. Actual freshness is shown by the last successful synchronization.
