Expectations are growing for expanded investment in AI data centers and the establishment of ultra-fast network infrastructure, leading to a broad rally in optical communication and optical semiconductor-related stocks and drawing market attention.

During the morning session on the 29th, within the optical communication and optical semiconductor theme, RF Materials recorded the highest gain, jumping 11.15%. This was followed by widespread advances across related stocks, including Jaram Technology up 10.81%, Bitgwajeonja (Light & Electron) up 8.10%, Kwangjeonja (Opto-Electronics) up 7.50%, Mercury up 7.23%, Korea Advanced Materials up 7.19%, Bitsaem Electronics up 6.65%, Seoul Semiconductor up 6.62%, Fiberpro up 6.62%, Daehan Optical Communication up 3.59%, and Hanmi Semiconductor up 1.55%.

As the spread of AI services causes data processing volumes to surge, global big tech companies are accelerating the expansion of data centers and the advancement of networks. Accordingly, demand for core components essential for ultra-fast data transmission—such as optical transceivers, optical fibers, optical cables, and optical semiconductors—is expected to increase rapidly.

Looking at individual stocks, Kwangjeonja is benefiting from expectations of growth in the AI and optical communication markets based on its optical sensor and semiconductor component technologies. Bitgwajeonja and Bitsaem Electronics reflect expectations for market expansion in the optical communication equipment and components sectors. Daehan Optical Communication is cited as a prime beneficiary of increased investments in data centers and communication networks, possessing production capabilities for optical fibers and cables.

Seoul Semiconductor continues to generate expectations for expansion in the next-generation light source market based on its competitiveness in LED and optical semiconductor technologies, while Hanmi Semiconductor is drawing attention as a core company in the semiconductor ecosystem, driven by rising demand for advanced packaging equipment for AI semiconductors.

The market predicts that as the competition to build AI data centers begins in earnest, the growth rate of the optical communication and optical semiconductor industries will accelerate. In particular, analysts note that the expansion of high-performance AI servers and ultra-fast network infrastructure is highly likely to lead to mid- to long-term earnings improvements for related component companies.

However, because expectations regarding AI investments tend to be quickly reflected in their stock prices, whether these companies actually secure more orders and improve their earnings is pointed out as the key variable that will determine future stock price trends.
