CIG's stock price surged 6.65% during intraday trading on Friday, reflecting strong investor buying interest.

The significant price movement appears to be driven by the company's impressive first-quarter financial results, which showed revenue growth of 43.98% year-over-year to RMB 1.287 billion and a staggering 276.44% increase in net profit attributable to shareholders to RMB 118 million. This earnings beat was primarily fueled by the rapid expansion of its high-speed optical module business.

Furthermore, the company indicated at its earnings briefing that demand for high-speed optical modules remains robust, with annualized capacity of 3.5 million units operating at high utilization rates. The company has completed small-batch shipments of its advanced 1.6T optical modules and is arranging volume deliveries, while actively expanding production capacity both domestically and overseas to meet demand for 800G and 1.6T products. These strong fundamentals and positive business outlook have bolstered investor confidence.
