Context This is a compensation award (RSUs), not an open-market purchase or sale. RSUs do not convey actual shares or voting rights until they vest and are settled; they are commonly used for executive and director compensation. Such grants are informational for investors but do not by themselves indicate immediate buying or selling pressure.
