  • Korea FT After-Hours Block Deal: Investment Opportunity or Red Flag?





    1. Korea FT After-Hours Block Deal: Key Takeaways

    On September 19, 2025, Korea FT saw an after-hours block deal with other corporations buying KRW 1.8 billion and foreign investors selling KRW 3 billion worth of shares. This KRW 1.6 billion transaction (approximately 0.8%) relative to the KRW 196.3 billion market capitalization could cause short-term stock price volatility.

    2. Why Did This Happen? Background and Analysis

    While there’s currently no market consensus, the purchase by other corporations can be interpreted as a positive sign. However, the selling by foreign investors may act as short-term downward pressure on the stock price. It’s crucial to understand whether the foreign selling was simply profit-taking or based on a negative assessment of the company’s fundamentals.

    3. Korea FT: A Fundamentally Sound Company?

    • Solid Existing Business: Korea FT maintains stable sales through its automotive parts manufacturing (carbon canisters, plastic filler necks, etc.) and continues to grow through supply contracts with global automakers.
    • Securing Future Growth Engines: The company is actively responding to future automotive market trends by pursuing new businesses such as ADAS software and VIM development. VIM, in particular, is in the final stages of development and holds high expectations as a future growth driver.
    • Strong Financial Structure: As of the first half of 2025, Korea FT achieved sales of KRW 398.2 billion and operating profit of KRW 27.2 billion. An operating profit margin of 6.85% and a low debt-to-equity ratio of 13.71% demonstrate stable financial health.
    • Risk Factors Exist: Low operating rates at the Chinese subsidiary, uncertainty surrounding the market entry of new businesses, exchange rate fluctuations, and raw material price volatility are potential risk factors.

    4. What’s Next? Future Outlook and Investment Strategy

    In the short term, investors should monitor the continuation of foreign selling and the scale of purchases by other corporations. In the medium to long term, maintaining competitiveness in Korea FT’s auto parts business and the successful market entry of new businesses will be key drivers of stock price growth.

    5. Action Plan for Investors

    How will the after-hours block deal affect the stock price?

    The after-hours block deal can cause short-term stock price volatility.

The future stock price trend will depend on the nature of the buying entities and the reasons behind the foreign selling.

    What are the key considerations when investing in Korea FT?

    Investors should be aware of potential risk factors such as low operating rates at the Chinese subsidiary, uncertainties surrounding the market entry of new businesses, and exchange rate and raw material price fluctuations.
