SICC (Tianyu Advanced) saw its stock price plummet 11.07% during intraday trading, marking a sharp reversal following recent gains driven by SiC-AI demand narratives.

The decline was triggered by market concerns over a major shareholder reducing their stake from 8.00% to 6.83%, crossing the 1% disclosure threshold. Additionally, four block trades were executed at a 10% discount to market price with a combined transaction value exceeding RMB 80 million, which the market interpreted as a bearish signal.

These developments raised concerns about near-term selling pressure and prompted profit-taking after the stock's recent rally, with investors viewing the concentrated shareholder disposals and deeply discounted bulk transactions as indicators of potential further downward pressure.
