What does this mean?

Company leaders: The people who run a company or sit on its board, plus anyone who owns more than 10% of it. The law calls them "insiders."
Big shareholder: A person or fund that owns more than 10% of the company.
Pre-planned sale: A sale scheduled months ahead with a written plan, so it says less about what the person thinks today.
Unplanned sale: A sale the person decided on at the time, which can say more.
Our rating: A quick label from simple rules (how big, who sold, how many sold together). It is our opinion, not a fact and not advice.
