On June 18, Yangtze Optical Fibre and Cable (06869.HK) fell 3.08% in regular trading, trading at 220.8 HKD/share, with turnover of approximately HKD 4.368 billion. The optical communications sector entered its second consecutive day of pullback following a brief stabilization and rebound on June 15-16.

On the news front, overseas research firm SemiAnalysis previously released a bearish report on CPO (Co-Packaged Optics) mass production timelines, compounded by expectations of significant price cuts for 800G optical modules, which weighed heavily on the sector. Although Nvidia subsequently issued a denial and panic sentiment was partially digested, market divergence over CPO commercialization progress and the long-term growth thesis of optical communications has not been fully resolved, weakening recovery momentum across the sector.

Within the Communications Equipment sector, peer stocks also faced broad pressure. ZTE fell 3.54% and Nanjing Panda Electronics dropped 6.27%, while CIG rose 2.74% and TRIGIANT gained 3.18%, reflecting mixed intra-sector performance.
