On the news front, the company recently announced that controlling shareholder CIG Cayman and its concert party Shanghai Kangling completed a combined reduction of 3,938,300 shares, representing 1.07% of total share capital. The reduction plan period has expired, raising market concerns over a potential new round of share sales. The reduction took place between May 13 and July 7, during which CIG Cayman's stake fell to 8.02% and Shanghai Kangling's to 1.19%.

Meanwhile, the optical communications sector remained broadly under pressure. Despite earlier clarification that reports of a U.S. FCC ban on Chinese optical modules were a misinterpretation, lingering geopolitical policy uncertainty continues to weigh on sector valuations. Within the Communications Equipment sector, ZJ INNOLIGHT fell 4.5%, YOFC fell 0.97%, and ZTE declined 0.73%. CIG had previously rallied over 18% in the prior week, amplifying short-term profit-taking pressure.
