As global data usage surges, so does the need for the kind of high-performance fiber Corning specializes in.

Teradyne (TER), a major player in semiconductor testing equipment, has climbed 59.8%. With the world leaning heavier into AI, electric vehicles, and automation, Teradyne’s role in ensuring chip reliability has become more critical than ever.

Western Digital (WDC) rounds out the top four with a 58.3% increase. Amid a data explosion driven by AI and cloud computing, demand for efficient data storage solutions has surged—putting WDC’s hard drives and solid-state storage products squarely in demand.

While past performance doesn’t guarantee future results, these stocks reflect broader trends: energy security, advanced manufacturing, and data infrastructure. They suggest that value in 2026 isn’t just coming from flashy startups, but from established companies adapting decisively to a changing world. For investors, that could mean smart opportunities beyond the usual suspects.
