HK Stock Market Move | YOFC(06869) rose more than 7% Fiber optic prices rise steadily Changes in industry supply and demand patterns

YOFC (06869) rose more than 7%, with the stock price increasing by more than 70% in the past month. As of the time of writing, it has risen by 7.27%, reaching HKD 90.75 with a turnover of HKD 26.25 billion. On the news front, according to a Huatai research report on February 2nd, in January 2026, the price of G.652.D single-mode optical fiber in the Chinese market hit a new high in nearly seven years, with an average price exceeding 35 yuan per core kilometer. The bank believes that the price increase is mainly due to changes in the industry supply and demand pattern: on the demand side, the global demand for optical fibers is increasing due to AI data centers and drones, with Meta and Corning signing a $6 billion AI data center optical cable contract, while on the supply side, the production capacity of key materials for optical fiber preforms in the upstream may not be able to increase rapidly in the short term. A report from Guotai Haitong points out that the trend of price increase in the optical fiber industry is clear, with hollow cores bringing new increments. Recently, the price of loose fibers has continued to rise, and the bank believes that with the upcoming telecommunications and mobile operator group purchases, as well as the strong industry restocking demand before the Spring Festival, prices are expected to continue to rise. In this context, the bank believes that domestic market major customers are also likely to accept price increases, confirming the sector's volatility.
