    1. What Happened?

    After the market closed on August 28, 2025, a large block of Enchem shares (103,397 shares, approximately 8.2 billion KRW) was traded. Institutional investors net bought 7.2 billion KRW, while foreign investors net sold 8.7 billion KRW.

    2. Why Did This Happen?

    The long-term stock price depends on fundamental improvements, especially increased capacity utilization, sales recovery, and new business performance. Macroeconomic factors like EV/secondary battery market growth, exchange rates, and interest rates will also have an impact.

    What should investors do?

    Focus on fundamental improvements rather than short-term supply-demand factors. Stay informed by monitoring relevant information and invest cautiously.
