Frequently asked questions
Are QMCO insiders buying or selling?
Over the transactions on record, QMCO insiders have been net buyers, with about $24.47M in stock sold across 46 sales, against 10 open-market purchases.
Does insider selling at QMCO 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 QMCO insiders are selling the most?
Recent selling is concentrated in a few names. PACIFIC, INVESTMENT MANAGEMENT CO LLC accounts for the largest share on record, with about $23.90M sold. Selling by one or two individuals matters less than broad selling across the whole leadership team, which is the pattern worth watching.
