Teradyne (TER) shares surged 6.02% in Tuesday's trading session following the release of its better-than-expected second-quarter earnings report. The company, a leading provider of automated test equipment, demonstrated resilience in the face of market challenges and capitalized on the growing demand for AI-related chip testing.
