Here's the hidden growth potential in machine-vision company Cognex Corporation (NASDAQ: CGNX), positioning and workflow-technology company Trimble (NASDAQ: TRMB), and Delta Air Lines (NYSE: DAL), and why all three are great stocks to buy for 2025. It's not easy when customers in your three major end markets are all under pressure, but that happened to Cognex over the last couple of years.
