Context RSUs are a common form of executive compensation and represent a contingent right to receive shares upon vesting — they are not immediate open-market purchases (which some investors view as a stronger bullish signal). The withheld shares are a routine, administrative step to cover tax liabilities and do not necessarily reflect a voluntary sale by the insider.
