Context
RSUs are a form of equity compensation that convert to shares if and when they vest; they do not represent an immediate purchase or sale. Grants to non-employee directors are common as routine compensation and do not, by themselves, indicate a director’s personal trading view. Purchases (direct buys) tend to be more informative about insider sentiment than routine awards.
