A Fake Nomura Report Shook China's Optical Module Stocks

A single screenshot was enough to move one of China’s most closely watched AI hardware stocks. On November 3, an image circulating in investment chat groups claimed that Nomura, the Japanese brokerage, had cut its target price for Zhongji Innocung to 330 yuan per share. The note carried both the company’s Shenzhen listing code, 300308.SZ, and its Hong Kong code, 03308.HK, and it spread quickly through groups where retail and professional investors trade tips side by side.
The timing mattered. Zhongji Innocung makes optical modules, the components that move data between servers inside AI data centers, and the sector’s mood has been fragile after a long run of gains. When a picture of a downgrade appears in that environment, sellers do not wait to check the source. The claim circulated widely enough to disturb trading in the stock and its peers before anyone had verified where the note came from.
Verification, when it came, was blunt. A reporter asked Nomura about the document, and a person at the firm said the matter was not true: the brokerage had never issued the report at all. That answer reframes the episode from a downgrade story into a forgery story. Someone produced a document bearing a major bank’s name, with a specific target price and the correct listing codes, and let the market do the rest.
For global readers, the context is that China’s optical module makers became some of the biggest beneficiaries of the AI build-out. Their shares have been volatile because their fortunes are tied to orders from overseas cloud companies and chip designers, and because expectations for the sector swing hard in both directions. In a market like that, a plausible-looking number can travel faster than any correction.
This is not the first time a screenshot has done real damage in Chinese markets. Chat groups and social feeds have become a parallel channel for research notes, and a forged page needs only a recognizable logo and a font that looks right. Once it is forwarded a few hundred times, the original source is usually lost, and traders are left reacting to an image rather than a document.
The company has not commented publicly on the claim, and the practical question now is what investors do with the next one. Neither the 330 yuan figure nor the note carrying it has any standing, but the price action it triggered was real for anyone who sold on it. Retail investors in particular have little way to check a broker’s research pipeline before the market opens.
The episode also points to a structural gap. Chinese regulators have repeatedly warned about fabricated information being used to pump or dump stocks, and market participants have long complained that rumors move faster than official channels. A denial issued hours later cannot undo trades already executed.
What to watch is whether the affected companies or the exchange move beyond denial. A formal statement, a request for an investigation, or a clarification of where the forged note first appeared would all signal that the industry wants to close the gap. Until then, the safest reading of any screenshot with a bank’s name on it is that it is unverified until the bank itself says otherwise.
