On September 30, CIG rose 5.14% in regular trading, trading at HK$111.0/share, with turnover of HK$197 million. The stock continued its rebound after a sharp selloff earlier in the week triggered by a proposed US bill restricting Chinese optical transceivers.

On the news front, Citi interpreted the S.5548 bill as targeting only federal national security system procurement rather than a comprehensive ban, noting short-term impact remains limited. Jefferies pointed out that the recently concluded US-China summit released a constructive tone emphasizing strategic stability, making a broad ban on Chinese optical modules in private data centers highly unlikely. Jefferies characterized the bill as policy noise at this stage. The bill, proposed on September 25 by bipartisan US senators, names major Chinese optical module suppliers but includes a five-year transition period and exemption mechanisms.
