Frequently asked questions
Are GCBC insiders buying or selling?
Over the transactions on record, GCBC insiders have been net buyers, with about $1.89M in stock sold across 18 sales, against 82 open-market purchases.
Does insider selling at GCBC 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.
Which GCBC insiders are selling the most?
Recent selling is concentrated in a few names. PLUMMER, MICHELLE M accounts for the largest share on record, with about $659214.41 sold. Selling by one or two individuals matters less than broad selling across the whole leadership team, which is the pattern worth watching.
