Frequently asked questions
Are GSIT insiders buying or selling?
Over the transactions on record, GSIT insiders have been net buyers, with about $4.54M in stock sold across 47 sales, against 15 open-market purchases.
Does insider selling at GSIT 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 GSIT insiders are selling the most?
Recent selling is concentrated in a few names. SHU, LEE-LEAN accounts for the largest share on record, with about $2.13M sold. Selling by one or two individuals matters less than broad selling across the whole leadership team, which is the pattern worth watching.
