Frequently asked questions
Are CMP insiders buying or selling?
Over the transactions on record, CMP insiders have been net buyers, with about $0.00 in stock sold across 0 sales. The entries tagged as buys are stock grants and option exercises recorded at $0, not open-market purchases.
Does insider selling at CMP mean the stock will fall?
Not by itself. Most executive selling is pre-scheduled through 10b5-1 plans filed months in advance, and insiders sell for diversification, taxes, and liquidity far more often than out of any view on the price. Insider buying is the stronger signal, especially when several insiders buy around the same time, because there is usually only one reason to put personal cash into the stock.
