Insiders buying against sellingWhat is a Rule 10b5-1 trading plan? A Rule 10b5-1 plan lets an insider fix future trades in advance, while holding no inside information, so later trades follow the plan, not a new decision.
Open-market purchases and sales reported on Form 4, by value. Awards, option exercises and shares withheld for tax are not counted. Whether a sale was under a Rule 10b5-1 plan is read from each Form 4 at the SEC (the box exists on filings since April 2023).
