Furukawa Electric Co., Ltd. <5801> surged over 16% on heavy volume, soaring to the \42,000 level and significantly surpassing its all-time high. The company has gained attention as a manufacturer of optical fiber and other components for AI data centers, with its business performance entering what appears to be a period of rapid growth, attracting investment capital. Recently, it has frequently ranked second in trading value after Kioxia Holdings, establishing its presence as a symbol stock of AI data center-related plays.

In the optical fiber sector, Fujikura Ltd. <5803> had previously led the way, but recently Furukawa Electric has emerged to take center stage. Fujikura's investor interest ignited in early spring of 2024, and its market capitalization has already expanded fifteenfold since that initial move. In contrast, Furukawa Electric's stock price lagged behind Fujikura in terms of timing, with momentum accelerating this year after a period of consolidation. Market observers note that "while Furukawa Electric is part of the big three and its earnings growth potential is no less impressive, its stock price had been lagging. However, given that its top line (revenue) exceeds that of peer Fujikura, it is attracting re-evaluation buying from overseas investors and others," according to a strategist at a mid-tier securities firm. Additionally, expectations are building for Furukawa Electric to expand its market share in next-generation cooling systems for data centers, an area where the company has clearly indicated its commitment.
