Context Restricted stock units are a form of compensation that convert to actual shares only if and when they vest; they do not represent immediately tradable shares. Because this was a grant for future delivery, it does not reflect an open-market purchase or sale and should be read as compensation-related insider activity rather than a direct market sentiment signal.
