Only open-market buys / sells (codes P/S) are a conviction signal; grants, option exercises, tax-withholding, and gifts are compensation mechanics, shown but greyed. The trailing 12-month tallies run to today but the store covers filings through 2026-06-30 only (SEC bulk data sets publish quarterly), so recent activity may be absent.

Source: the SEC bulk insider (Form 3/4/5) data sets — non-derivative transactions in the issuer's common stock, most recent first, covering filings through 2026-06-30. Insiders file within 2 business days of a transaction, but the bulk sets publish quarterly, so this store lags live filings; option/derivative lines are excluded.
