Context Grants to directors are commonly part of compensation plans (e.g., restricted stock or director equity awards) and do not necessarily reflect a personal cash investment or short‑term market view. Unlike open-market purchases, awards are less direct as a bullish signal but still increase the insider’s stake over time.
