Yangtze Optical Fibre and Cable (YOFC) stock soared 5.24% during intraday trading on Monday, reflecting strong investor interest in the optical communications sector.

The rally is primarily driven by a significant surge in optical fiber prices, with industry reports indicating increases of up to 650% compared to the same period last year. YOFC, as one of the world's largest optical fiber preform, fiber, and cable manufacturers, is seen as a primary beneficiary of this pricing upcycle. The company's strong financial performance, including a 20.40% year-over-year increase in net profit, further supports the bullish sentiment.

Industry analysts point to rigid supply-side constraints, particularly the lengthy 1.5 to 2-year expansion cycle for fiber preform capacity, as a key factor sustaining high prices. With demand for optical fiber expected to remain robust through 2027 due to AI computing power development and global data center construction, YOFC's market-leading position positions it to capitalize on this extended industry upcycle.
