On August 3, CIG rose 5.46% in regular trading, trading at 69.8 HKD/share, with turnover of HKD 211 million.

On the news front, the optical communications sector continues its recovery after a sharp correction that began on July 28. CIG's Hong Kong-listed shares had previously suffered a cumulative decline exceeding 30% over three trading days, while its A-shares triggered consecutive limit-down sessions and an abnormal trading volatility notice. The sector staged a collective rebound on July 31, with CIG surging over 17% in a single session. The current gain represents a continuation of this repair trend.

The company announced on July 30 that no material undisclosed information exists. Fundamentally, CIG forecasts first-half net attributable profit growth of 157% to 197%, driven by strong high-speed optical module demand from AI data center buildouts. The prior selloff was widely attributed to overseas sentiment contagion from US semiconductor weakness and crowded-trade unwinding rather than deteriorating fundamentals.
