Invested = shares acquired (buys, grants, option exercises) — insider adding to the position. Divested = shares reduced (sells, dispositions, tax-withholding) — cash flowing TO the insider. Net direction shows which side wins on dollar terms in each bucket. % of holder's stake not yet computed (pending Form 3/4 holdings ingest). See methodology. The two @ last price columns restate the same share counts at the most recent share price we read (close of 2026-10-19); they are a valuation, not a cash flow, and they move every day the market does.
