The computing power industrial chain staged another strong rally during today's A-share session. Key segments including optical modules (CPO), optical communication, and optical chips saw collective gains. The Tongdaxin CPO Index surged over 3% to hit fresh highs. Notably, Yangtze Optical Fibre and Cable (长飞光纤) rocketed to a limit-up within just 8 minutes after market open, reaching record highs.
Recent positive developments continue to buoy the sector. Research institutions highlight accelerating technological iterations and product innovations in large AI models, sustaining robust demand for computing power.
**Sector-Wide Rally**
After days of sideways trading at elevated levels, A-share computing power stocks erupted on December 22. Yangtze Optical Fibre, Shenzhen Tellus (特发信息), Hengtong Optic-Electric (亨通光电), and others hit limit-ups, while Changxin Borui (长芯博创) and Zhishang Technology (致尚科技) jumped over 12%. Analysts attribute this partly to the U.S. AI sector's strength last Friday, where Lumentum soared 10% and NVIDIA gained 4%.
**Domestic AI Momentum**
Beijing-based JiuZhangYunJi (九章云极), an AI infrastructure provider, recently added Beijing AI Industry Investment Fund as a shareholder, boosting registered capital to ¥48.85 million. Separately, Moore Threads (摩尔线程) unveiled its "Huagang" GPU architecture at its developer conference, promising enhanced computing density for upcoming AI chips. The firm also showcased breakthroughs in 10,000-card AI clusters capable of trillion-parameter model training.
**Tech Giants Double Down**
On December 18, ByteDance's Volcano Engine launched its Doubao 1.8 model and Seedance 1.5 pro for audiovisual creation. Meanwhile, Tencent restructured its AI divisions, appointing a chief AI scientist to bolster R&D.
**Institutional Outlook**
Guosheng Securities notes exploding demand for Doubao's API calls signals intense AI arms races among Chinese tech giants. With domestic GPU firms like Moore Threads and Muxi (沐曦股份) eyeing IPOs, and unicorns Zhipu (智谱) and Minimax preparing Hong Kong listings, CSC Financial expects sustained high computing power demand amid rapid model innovation. CICC predicts fiber optics may face shortages within two years as AI reshapes demand, with specialty fibers poised for breakthroughs.
