Chinese Optical Module Stocks Plunge Amid U.S. Import Ban Concerns
SHANGHAI/HONG KONG, Aug 5 – Shares of companies producing optical modules in China, like Zhongji Innolight, dropped sharply on Wednesday. This was in response to a report that the Trump administration is considering a ban on U.S. imports of new models of Chinese data center components.
The CSI300 Telecommunication Services Index fell by as much as 9% in early trading. Optical module makers reliant on exports, including Zhongji Innolight, Eoptolink Technology, and Suzhou TFC Optical Communications, were hit particularly hard.
Reports indicate the U.S. government is looking to impose restrictions on importing new Chinese optical transceivers. These components are crucial as they allow data to travel swiftly over fiber-optic cables within data centers.
This news poses a challenge to the already fragile confidence in China’s AI hardware market, which has recently experienced a significant sell-off. However, some analysts believe that the market reaction may be an overreaction to the news.
In a recent note, Jefferies mentioned, “We see a low risk that this ban will materialize under Trump.” They suggest that this could be a negotiation tactic by the U.S. ahead of President Xi’s visit to the U.S. in September, especially in light of China’s export controls on rare earth materials, which impact the U.S. optics sector.
The psychological impact of these developments was evident, with investors quickly selling off optical module stocks, while shares of domestic chipmakers saw an upswing.
Zhongji Innolight, which ranks as the 10th largest publicly listed company in China by market value, saw its shares tumble by around 10% in both Shanghai and Hong Kong. The company reported that 62% of its revenue came from the U.S. in the first quarter and previously warned that escalating trade tensions could severely affect its performance.
Eoptolink Technology, which earns 96% of its revenue from international markets, also lost 10% of its stock value, while TFC Optical, another company heavily reliant on foreign sales, dropped roughly 6%.
Legal expert Zhan Kai from Dacheng law firm in Shanghai commented, “The U.S. actions are not surprising, as its policies toward China are influenced by concerns over trade imbalances and the intent to slow China’s technological growth.”
He further noted that the U.S. is shifting focus from blocking technology transfers to restricting Chinese investments and access to its market. For Chinese firms, the priority now should be diversifying their client bases and market targets, instead of just obtaining technology.
