Context: These were outright sales, not exercises of options or gifts. Sales by insiders are common and can reflect many reasons (taxes, diversification, estate planning); they do not by themselves indicate company performance or insider sentiment. Purchases are generally more informative about an insider’s positive view of the stock.
