Fujikura, a 139-year-old Japanese company specializing in fiber optic cables for data centers, has emerged as a leading performer on the Nikkei 225 index, with its shares surging over 400% in 2024. This dramatic increase is attributed to the growing demand for artificial intelligence technologies, which has significantly boosted the company's market value. The surge in Fujikura's stock reflects the broader trend of AI-related companies experiencing substantial gains, as evidenced by other firms in the sector. Notably, a Texas landowner company has also seen its stock rally by 230% this year, driven by similar demand for data center infrastructure.
