Nick L. Stanage bought 4,000 shares of AMETEK (AME) on the open market on Aug. 11, 2026, paying $255.85 per share for a total investment of about $1.02 million. Open-market purchases are closely watched because they involve the insider using personal funds to increase exposure to the stock, unlike stock awards or option exercises that can be part of routine compensation. Stanage is listed as an insider, meaning he has access to non-public operational information and is considered a company “insider” under securities rules even if he is not the CEO or CFO. A purchase of this size can matter to retail investors because it represents a deliberate decision to add shares at current prices. The disclosure also notes no indication the trade was made under a pre-scheduled 10b5-1 plan, which can make the timing appear more discretionary. Recent activity at AMETEK has been mixed over the past 30 days. Stanage’s $1.02 million buy followed a sizable sale by David F. Hermance, who sold about $1.68 million worth of shares on Aug. 7. One buy and one sell close together can reflect different personal financial needs or portfolio decisions, so investors often look for whether additional insiders follow with similar buying or selling.
