Shares of prominent Chinese optical-module companies experienced a volatile trading session on Wednesday. The market reacted initially to reports of proposed US restrictions that could potentially bar these firms from participating in future American artificial intelligence data center projects. Following the initial sell-off, however, stock prices saw a partial recovery as market analysts weighed in on the feasibility and potential scope of the new rules.

Industry experts cited by the South China Morning Post suggest that the proposed curbs are likely to be "mild" in their actual application. A primary argument for this outlook is the significant reliance of the US technology sector on Chinese manufacturing capabilities. Analysts noted that any attempt to fully decouple these supply chains would face substantial logistical and economic hurdles, potentially leaving existing arrangements largely intact. Despite the late-day rebound, some major players, such as Zhongji Innolight, still closed the trading day with losses, finishing down 7.3 percent in Shenzhen and 6.7 percent in Hong Kong. The market remains sensitive to geopolitical tensions, as investors continue to evaluate how future US trade policy might affect the high-growth AI hardware sector.
