YOFC's stock price surged 8.36% during intraday trading on Friday, reflecting a significant upward movement in the company's valuation.

The sharp increase appears to be driven primarily by China Mobile's release of a centralized procurement tender for ordinary optical cables, which totaled 69.22 million core-kilometers over nine months. Notably, the maximum limit price set in the tender is approximately RMB 100 per core-kilometer, a figure that substantially exceeds prior market expectations and suggests robust pricing power in the sector. Industry analysis indicates that the pricing level is so high that some smaller manufacturers may not participate in the bidding, highlighting tight supply conditions.

Furthermore, the positive sentiment is bolstered by several optical communications companies issuing strong first-half earnings previews, with projected net profit growth ranging from 170% to over 1,100% year-over-year. This reinforces the view that the industry is in a high-prosperity cycle. The broader optical communications sector experienced a collective rally, contributing to the upward momentum for YOFC.
