Everything on this page is public record — SEC Form 4 filings and congressional disclosures — alongside any INSIDER SCANNER research case for this company.
Insider flow: Selling only — a count of disclosed transactions, not a rating or a recommendation.
Every reported transaction, positioned by trade date. Purchases sit above the axis, sales below; circle area is proportional to dollar value. No share-price line is drawn — this feed carries transaction prices only, and a price history inferred from them would imply market data the filings do not contain.
One row per insider, one cell per reported transaction, shaded by value. Repeat buying and activity clustered in time are visible at a glance.
Every open-market transaction disclosed for MATX in the synced window. Values are the insider's own, as filed.
