The cluster of C-suite buys is directionally bullish but too small in dollar terms to move the stock on its own. Monitor for any upcoming earnings release or material agreement that may have prompted the purchases.
Price Chart
Executive Summary
Five C-suite insiders at Amrize Ltd made open-market purchases totaling ~$680K over a 7-day window, led by the CFO ($283K) and Chief People Officer ($249K).
