On May 28, Tianyu Advanced (02631) fell 8.32% in regular trading, trading at HKD 113.5/share, with trading volume of HKD 82.59 million. The stock experienced a sharp reversal following the previous session's surge of over 16%.

On the news front, a shareholder holding more than 5% of the company's shares, together with concert parties, reduced their stake from 8.00% to 6.83%, triggering the 1% disclosure threshold. Additionally, on May 27, four block trades were executed at a 10% discount to market price, with a combined transaction value exceeding RMB 80 million. The concentration of shareholder disposals and deeply discounted bulk transactions has been interpreted by the market as a bearish signal, raising concerns over near-term selling pressure and prompting profit-taking after the stock's sharp rally driven by SiC-AI demand narratives.
