On June 30, CIG Shanghai rose 3.26% in regular trading, trading at HKD 148.9/share, with turnover of HKD 301 million.

The rebound follows a 3.68% decline on June 26, which was triggered by concentrated profit-taking after the stock's cumulative gain exceeded 20% over three consecutive trading days. The past two sessions have seen sustained technical recovery from oversold levels.

On fundamentals, the company reported Q1 net profit attributable to shareholders surging 276.44% year-over-year, driven by scaled mass production of 800G optical modules and completion of small-batch shipments of 1.6T products. Robust AI computing demand continues to fuel strong high-speed optical module orders. Additionally, sector peer YOFC gained over 6% on the same day, reflecting broad strength across the optical communications industry that provided further tailwind to the stock.
