Context RSUs are a form of compensation that convert into shares when they vest; they do not represent an immediate cash purchase or sale. For retail investors, director RSU grants are routine compensation and do not by themselves indicate buying or selling sentiment. The economic benefit (and tax event) typically occurs at vesting when shares are delivered.
