YOFC's stock experienced a significant decline, plummeting 5.04% during intraday trading. The sharp drop follows a volatile pattern for the fiber optic company's shares.

The movement is attributed to persistent profit-taking from high-level holders and continued net selling by southbound capital, which has kept short-term selling pressure elevated. Furthermore, technical selling pressure resumed after the stock rebounded over 10% in the previous trading session, creating a pattern where positive news triggers selling rather than sustained buying momentum.

This selling pressure persists despite several fundamentally supportive factors for the company, indicating that short-term technical factors and investor positioning are currently dominating price action over the company's positive outlook and financial performance.
