How to Read This Page
These are the trades an insider chose to make with their own money, not grants, option exercises or tax withholding. A purchase is the stronger signal (why buys carry more information than sales), and an insider who buys is locked out of selling for six months by the short-swing rule. Several insiders buying at the same company in the same week is cluster buying, the pattern the research literature rates highest. The window here is 180 days; the full filing history lives on EDGAR.
