On June 10, Yangtze Optical Fibre and Cable (YOFC) declined 4.23% in regular trading, trading at 243.2 HKD/share, with trading volume of HKD 909 million. The decline came as the optical communications sector extended its weak trend amid intensifying industry headwinds.

On the news front, despite a brief rebound in the prior session driven by strength in US optical communications stocks and index inclusion expectations, multiple structural concerns weighed on sentiment. Industry overcapacity fears are escalating as aggressive expansion of preform and fiber-drawing capacity could lead to oversupply by next year. Meanwhile, reports suggest 800G optical module prices face cuts exceeding 60%, pressuring gross margins and raising volume-up-price-down risks. Additionally, NVIDIA is advancing a copper-over-fiber strategy, with CPO solutions being trialed as replacements for traditional optical modules, challenging the sector's long-term growth narrative.

YOFC's dynamic PE ratio remains at historically extreme levels following a 15x surge over the past year. Profit-taking pressure persists as large accumulated gains incentivize institutional selling. Peers in the sector also declined, with Trigiant Group down 5.9% and Cambridge Technology down 3.66%.
