What happened
On September 7, shares of Xingye Technology opened with a one-word limit-down, trading at 20.93 yuan per share, giving the company a market value of approximately 6.186 billion yuan.
The drop follows an announcement on the evening of September 4 that the company had received a 'Case Filing Notice' from the China Securities Regulatory Commission (CSRC), though specific details of the alleged violations were not disclosed.
The company stated it would cooperate fully with the CSRC's investigation and that its production and operations remain normal, with no major impact expected from the probe.
Why it matters
The investigation adds uncertainty to Xingye Technology's recent surge, which was fueled by its June announcement of a planned acquisition of indium phosphide substrate assets for up to 55 million yuan in cash, marking its foray into the photovoltaic sector.
The stock had been a standout performer this year, rising from around 14 yuan at the start of the year to a high of 23.26 yuan by September 4, despite a brief dip to 11.93 yuan in late March.
Investors will be watching for further disclosures from the CSRC probe, as the company's cross-industry move into solar-related materials had drawn significant market attention.
