STOCKS | Yuanjie Technology Shares Jump 75.32% as Company Flags Demand Risks

Yuanjie Technology said its products are mainly used in optical communications and that demand can be affected by trends in downstream telecom and data center markets. According to Jin10, the company issued an abnormal trading announcement stating that its share price rose a cumulative 75.32% from May 18, 2026, to June 30, 2026, significantly outperforming related indices such as the STAR Composite Index and the STAR 50. The company said the optical chip industry sits upstream in the optical communications supply chain, and demand is sensitive to downstream market conditions. It warned that if future downstream demand falls short of expectations and weakens sharply or remains depressed, its future operating performance could face volatility. Yuanjie Technology also said that if the data center market, the AI industry, or both develop below expectations, or if product iteration in the data center segment accelerates or competition intensifies, its sales revenue from the data center market would be materially affected.
