On September 11, CIG (06166.HK) fell 5.1% in regular trading to HKD 116.4 per share, with turnover of HKD 961 million. The stock had opened higher on positive news that the U.S. FCC's final rule on communications supply chain security did not directly include major Chinese optical communications companies on its restriction list, alleviating prior market concerns. However, gains quickly faded as selling pressure mounted.

The reversal comes after an extraordinary multi-day rally. CIG surged over 22% on September 7, continued rising 5-9% on September 8, and gained another 5% on September 10, driven by strong H1 results — revenue of RMB 2.705 billion (+32.92% YoY) and net profit of RMB 328 million (+171.08% YoY) — alongside 800G optical module mass shipments, 1.6T production plans for H2, and the CIOE expo showcase. Exchange filings also revealed position transfers totaling HKD 335 million on September 10, with 676,400 shares moved out of HSBC.
