Context

• This was a routine tax-withholding action (company retains shares to satisfy tax liability on vesting), not an open-market sale or a purchase, so it does not necessarily signal the insider’s view of the stock. For retail investors, purchases and open-market sales are usually more informative than withholding-for-taxes transactions.
