Zhangjiang Hi-Tech Park issues trading risk warning after stock surge

Shanghai Zhangjiang Hi-Tech Park Development Co., Ltd. announced a risk warning due to abnormal stock trading. The company's stock experienced a cumulative deviation of 20% in its daily closing price over three consecutive trading days (September 19, 22, and 23, 2025). This triggered an abnormal fluctuation disclosure on September 24, 2025. On September 25, 2025, the stock closed at its daily limit up, indicating a significant short-term increase.

The company highlighted that its stock price has notably diverged from the industry average and the SSE Composite Index growth, suggesting a risk of irrational speculation. The company emphasized that its main business—the construction and operation of industrial space carriers in Zhangjiang Science City and leading industry investments—has not undergone any significant changes.

As of September 24, 2025, the company's trailing price-to-earnings (P/E) ratio stood at 72.5, and its price-to-book (P/B) ratio was 5.95. These figures are considerably higher than the industry averages for "Park Development (Yangtze)" as per Wind Information, which recorded a trailing P/E of 57.85 and a P/B of 1.81. Investors are advised to exercise caution and make rational investment decisions given these disparities.
