Frequently asked questions
Are SNDX insiders buying or selling?
Over the transactions on record, SNDX insiders have been net buyers, with about $0.00 in stock sold across 0 sales, against 9 open-market purchases.
Does insider selling at SNDX 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.
