Context
These entries reflect routine RSU vesting and tax-withholding (a non-market sale to satisfy tax obligations), not an open-market sale or purchase. The derivative code (M) here represents conversion of RSUs into common stock; the F-code disposals are shares withheld for taxes (a cashless withholding). Such withholding is standard and does not necessarily indicate the insider’s market view.
