An entry means this company met that edition’s displayed cluster or top-buyer threshold. Missing weeks do not mean no insider transaction occurred. All figures are derived from SEC Form 4 filings; open-market buys minus sales are shown as net only when every transaction value was disclosed.
How to read this: an open-market purchase (Form 4 code P) is a buy at the market price with the insider’s own money, as opposed to a grant, award or option exercise; an open-market sale is code S. When two or more distinct insiders report open-market purchases in the same 90-day window, this site labels that a cluster — a definition, not a forecast; see insider cluster buying. “Held after” is Form 4 Table I column 5; “Change” = shares ÷ holdings before the trade (held after − shares for an acquisition, held after + shares for a disposition).
