On September 29, CIG rose 5.5% in regular trading, trading at HK$107.6/share, with turnover of HK$491 million. The stock rebounded from the prior session's sharp selloff, when it had declined nearly 12% amid a broad optical communication sector rout.

On the news front, Citi issued a note clarifying that the US optical module restriction bill is not a comprehensive ban but only targets federal national security system procurement, with limited short-term impact. Jefferies further noted that the recently concluded US-China meeting released a positive atmosphere emphasizing constructive strategic stability, and assessed the probability of the US banning Chinese optical modules from private data centers as extremely low, characterizing the bill as largely policy noise. These reassurances helped stabilize the optical communication sector broadly.

Within the Communications Equipment sector, YOFC surged 8.49%, ZJ Innolight gained 2.72%, while ZTE slipped 1.72%, COMBA declined 0.47%, and VTECH HOLDINGS edged down 0.38%.
