What Happened

Context
Tax-withholding on RSU vesting is common and reflects the employer retaining shares to cover tax liabilities; it does not necessarily indicate the insider is selling shares on the open market or changing their view of the stock. For retail investors, purchase transactions tend to be more informative about insider sentiment; withholding events are administrative and routine.
