Nov. 3 — A screenshot purporting to be a Nomura research note lowering Zhongji Xuchuang’s A‑share price target to 330 yuan circulated rapidly in investor chat groups, briefly stirring the already sensitive optical‑module sector and impacting the stock.

There is no record of a formal report, author signature, report number or earnings‑calculation supporting a 330 yuan PT; the circulated content is false information.
