HK Stock Market Move | Optical communication concept stocks rise against the market, YOFC (06869) up more than 7%, TIME INTERCON (01729) up more than 6%

Concept stocks of optical communication rose against the market, as of press time, YOFC (06869) rose by 7.27%, to 84.1 Hong Kong dollars; TIME INTERCON (01729) rose by 6.07%, to 15.72 Hong Kong dollars; Hongteng Precision (06088) rose by 4.68%, to 4.92 Hong Kong dollars; Cig Shanghai (06166) rose by 1.52%, to 83.25 Hong Kong dollars. On the news front, American tech giants Meta and Microsoft both indicated in their latest financial reports that the tight supply of AI computing power will continue through 2026. Both companies' capital expenditures in the fourth quarter were higher than market expectations. Additionally, there has been strong demand for inference and training computing power overseas, leading to price increases by Amazon Web Services and Google Cloud. On the inference side, products like MoltBot (formerly ClawdBot) and Claude Code are accelerating deployment, significantly increasing demand for cloud computing resources, with token calls increasing rapidly for 2-3 weeks since the beginning of 2026. CITIC SEC pointed out that the surge in demand for AI computing power is driving the upgrade of the optical communication industry, with overseas cloud providers and TSMC continuing to expand their capital expenditures, confirming strong demand for AI infrastructure and bringing about strong demand for high-speed optical modules. Although there is a short-term supply gap in high-speed optical chips and other materials, upstream manufacturers are actively expanding production, coupled with the increasing penetration of silicon photonics solutions, the supply chain bottleneck is expected to ease. In terms of technological iteration, NPO is becoming a key transitional solution at the Scale up level due to its advantages in low power consumption, high bandwidth, and maintainability. Leading companies have already taken the lead in layout, driving the industry towards a more efficient optical interconnection architecture. The future development potential of domestic optical communication leading companies looks promising.
