See our latest analysis for Amphenol.

While Amphenol’s recent surge has grabbed the spotlight, it is part of a year marked by strong momentum. The stock has delivered a remarkable year-to-date share price return of over 82%, and its one-year total shareholder return stands at an impressive 89% as steady growth and market optimism drive further gains.

If Amphenol’s strong run has you wondering what other stocks are on the move, consider this the perfect chance to discover fast growing stocks with high insider ownership.

Yet with shares now hovering just below analyst price targets after such rapid gains, the question is whether Amphenol still offers value to new investors or if the market has already priced in future growth.
