Context
RSU grants are compensation, not open-market purchases; the award itself is generally a neutral-to-positive signal about retention/compensation but does not by itself indicate the insider is buying stock. Share withholding to cover taxes is a common administrative step when RSUs vest and typically does not reflect a decision to sell for investment reasons.
