CIG's stock price soared 5.13% during intraday trading, marking a significant recovery move. The surge was part of a broad-based rally across the optical communication sector in the Hong Kong market.

The sharp gain follows a steep decline earlier in the week after the stock was added to the short-sellable securities list, creating technical conditions ripe for an oversold rebound. The sector-wide positive sentiment provided additional momentum for the recovery.

Fundamentally, the company remains strong with its first-quarter net profit attributable to shareholders surging 276.44% year-over-year. The robust performance is supported by global demand for high-speed optical modules, with CIG's 800G silicon photonics modules already in volume delivery to North American clients and its 1.6T products entering the mass production phase.
