YOFC's stock price plummeted 6.20% in intraday trading, extending the recent selling pressure on the optical fiber and cable manufacturer.

The decline represents a classic "sell-the-news" pattern following the company's profit alert on July 14, which forecasted H1 net profit of RMB 2.4-3.0 billion, representing 711%-914% year-over-year growth driven by AI data center demand. Despite this positive catalyst and Morgan Stanley's subsequent upgrade to Overweight with a HK$230 target price, heavy profit-taking has dominated trading as the stock retraced over 50% from its June peak.

Compounding the selling pressure, southbound funds have net sold approximately 20 million shares over the past five trading days, while the third-largest shareholder Changjiang Communication completed a disposal of roughly one million shares worth RMB 412 million. Additionally, New York State's executive order halting large-scale data center construction has weighed broadly on AI hardware stocks this week, contributing to the negative sentiment around YOFC.
