How to Read MASI Insider Activity
Net insider activity is balanced over the trailing twelve months: 3 buys against 3 sales. Balanced activity typically reflects routine compensation-related vesting and tax-driven liquidity rather than directional information signals. The transaction table above includes the filer's reporting name, transaction type, share count, per-share price, and total dollar value where computable. For options traders, insider activity is one input to event-driven sizing alongside earnings calendar, analyst-rating cluster moves, and the implied-vol surface. Form 4 filings (the dominant Section 16 reporting form) must be submitted within two business days of the transaction; clusters of buys across multiple insiders within a short window are the strongest informational pattern. SEC EDGAR carries the underlying source filings for verification and additional historical depth.
