On August 19, ESTUN fell 6.18% in regular trading, trading at HK$19.34 per share, with turnover of approximately HK$42.08 million. The decline came one day after the company's A-shares hit the daily limit-up of 10%, closing at RMB 40.04 with a turnover rate of 15.53%.

On the news front, institutional investors and northbound capital exited aggressively at elevated levels following the A-share surge. Dragon-and-Tiger List data revealed that institutional seats net sold RMB 171 million, while Shenzhen-Hong Kong Stock Connect recorded net outflows of RMB 66.85 million, sending a clear signal of concentrated capital withdrawal at highs. The company's dynamic price-to-earnings ratio stands at 297.67x, with a non-recurring adjusted PE of 1,724.41x, indicating significant valuation pressure. Additionally, the company's previously announced acquisition of the persistently loss-making Estun Codroid from its controlling shareholder at a premium exceeding 900% continues to weigh on market sentiment in Hong Kong.
