Yangtze Optical Fibre and Cable (YOFC) saw its stock price plummet 7.72% during intraday trading on Friday, marking a significant decline for the optical fiber and cable manufacturer.

The sharp drop comes as short-term profit-taking pressure intensifies following a period of dramatic gains for the company. YOFC had previously experienced consecutive daily limit-up moves in its A-shares, prompting the company to issue an abnormal trading announcement that cautioned investors about uncertainty in product price volatility despite the global optical fiber and cable industry being in an upcycle.

Additionally, the broader communications equipment sector showed notable weakness during the session, with several sector peers also declining, which contributed to the downward pressure on YOFC's stock price.
