Context
This was a routine RSU vesting and tax-withholding action (a non‑market transaction), not an open‑market sale or purchase. Code M indicates conversion/exercise of a derivative (RSU → common shares); code F indicates shares were used to satisfy tax obligations. Such withholding is standard and does not, by itself, indicate insider sentiment about the stock.
