On September 10, YOFC fell 3.59% in regular trading, trading at 177.2 HKD/share, with turnover of approximately 110 million HKD. The stock had surged 9.99% on September 9, touching an intraday high of 196.3 HKD, with significant cumulative gains over the prior three trading sessions.

The decline was driven by broad profit-taking across the optical communication sector following a sustained multi-day rally. Peers including ZJ Innolight, MEIG, and CIG also declined. The prior rally was catalyzed by Goldman Sachs substantially raising its global optical module shipment forecasts, upgrading 1.6T and above product volume estimates by 29% to 50%, alongside the opening of the China International Optoelectronic Exposition showcasing 1.6T and CPO new products, and an overnight surge in US optical communication stocks.

Goldman Sachs maintains a target price of 292 HKD for YOFC with a neutral rating, expecting sequential revenue growth driven by higher optical fiber project pricing and product mix upgrades toward AI data center applications. The company reported H1 net profit of approximately 2.925 billion RMB, up 889% year-over-year.
