Why Tower Semiconductor Rallied Over 30% This Week
2026-03-20 06:57:00 ET
Shares of specialty node semiconductor manufacturer Tower Semiconductor (NASDAQ: TSEM) rallied 31.5% this week as of the end of Thursday's trading, according to data from S&P Global Market Intelligence .
Tower benefited from continued enthusiasm around artificial intelligence infrastructure, which got several boosts this week. Not only did Nvidia hold its GTC conference and certain memory companies report blockbuster earnings, but a big silicon photonics conference held mid-week contributed to the outsize gain.
Tower is a leading foundry for "SiPho" chips, so it followed suit with a big rally. In addition, Tower made a couple of technology-related announcements this week, contributing to the optimism.
