On May 27, Yangtze Optical Fibre and Cable declined 3.09% in regular trading, trading at 207.0 HKD/share, with trading volume of HKD 844 million. The stock has retreated over 25% from its historical high of 283 HKD.

The decline follows the near-halving of Japanese fiber optic manufacturer Fujikura's stock price in the week ending May 20, sparking concerns over material bottlenecks and supply chain constraints facing data center projects. Other Japanese peers including Furukawa Electric and Sumitomo Electric also underperformed the Nikkei 225 index during this period. Market participants are increasingly questioning the sustainability of the AI infrastructure boom. Additionally, UBS previously noted that the company's Q1 net profit of RMB 495 million significantly missed buy-side expectations of RMB 800 million to RMB 1 billion, predicting negative near-term market reaction. The ongoing profit-taking trend has extended into a second consecutive session.
