On June 12, Yangtze Optical Fibre and Cable (06869) rose 3.21% in regular trading to HK$236.8, with turnover of HK$1.352 billion. The stock rebounded after two consecutive sessions of steep declines totaling over 12%, which were triggered by concerns over CPO commercialization delays and 800G optical module price cuts exceeding 60%.

Southbound funds had accumulated net purchases of the stock for five consecutive trading days through June 10, with cumulative net inflows reaching HK$2.307 billion, signaling sustained institutional buying interest despite the recent pullback. The prior correction was catalyzed by a research report from SemiAnalysis published on June 9 that pushed back CPO large-scale commercialization timelines to 2028-2029, significantly later than market expectations, while NVIDIA's strategy of advancing copper-based interconnects over optical solutions further weighed on sector sentiment.
