YOFC's stock surged 5.02% during intraday trading on Friday, following news of a significant shareholder transaction and positive analyst commentary on the company's financial outlook.

According to a filing with the Hong Kong Stock Exchange, a shareholder transferred holdings worth approximately HK$2.88 billion from Standard Chartered Bank (Hong Kong) to The Hongkong and Shanghai Banking Corporation Limited, representing 2.96% of the company's shares. Such a large-scale transfer between major financial institutions can signal confidence or strategic repositioning in the stock.

Analysts from Huatai Securities noted that the company's first-quarter profit growth significantly outpaced revenue growth, driven by a substantial improvement in gross margin. With fiber optic prices showing a month-on-month upward trend and the expectation that higher-priced orders will be recognized starting from the second quarter, the firm is optimistic about an accelerated release of profit elasticity. The company's performance is anticipated to see significant enhancement, supported by the rising prosperity of its core fiber optic cable business and diversified operations such as optical interconnect components.
