YOFC's stock plummeted 10.88% during the intraday session, extending a deep correction in the optical communications sector.
The decline is attributed to market concerns over accelerating capacity expansion in the fiber optic industry, with new entrants such as Han's Laser and GCL-Poly pursuing high-end products like hollow-core and multi-core fibers. This is expected to intensify competition and pressure incumbent margins. Additionally, Corning's Glass Bridge glass optical interconnect platform has raised fears about long-term demand for midstream fiber components, contributing to short-term funds de-rating sector valuations.
Despite the sell-off, Nomura maintains a Buy rating on YOFC with a target price of HK$266, based on a forward P/E of 23.7x on FY2027 EPS estimates.
