A core part of the bull thesis for hedge funds with regards to AMETEK, Inc. (NYSE:AME) is the growth model. The company is a prolific acquirer of small to mid-sized niche technology leaders. In early 2026, CEO David Zapico reiterated the company’s commitment to deploying cash flows into acquisitions. Hedge funds are also attracted to the proprietary nature of AMETEK’s products. The company operates through two main segments: Electronic Instruments (EIG) and Electromechanical (EMG). Because many of their instruments are mission-critical, like aerospace sensors, medical power supplies, and laboratory equipment, but represent a small fraction of a customer’s total cost, AMETEK possesses significant pricing power.
