  • Techwing’s After-Hours Block Trade: A Sign of Soaring Growth with HBM?

    What Happened?

    A significant after-hours block trade of 123,947 Techwing shares, totaling approximately 4.1 billion KRW, took place on August 29, 2025. This considerable transaction, relative to the company’s market capitalization, suggests concentrated buying activity from specific investors.

    Why Does This Matter?

    The timing of this block trade, coinciding with net buying by foreign investors, is particularly noteworthy. This foreign investment influx raises the likelihood of further institutional buying, potentially creating upward momentum for the stock price.

    • HBM Testing Equipment Leadership: Techwing is poised to benefit significantly from the growth of the AI market, holding a strong competitive position in the HBM testing equipment sector.
    • Solid Fundamentals: Despite a decrease in revenue, Techwing’s 2025 half-year results demonstrate improved operating and net profits, indicating a strengthening financial position.

    What Should Investors Do?

    In the short term, close monitoring of market trends and trading volume following the block trade is crucial. A long-term perspective requires ongoing observation of HBM market growth, Techwing’s technological competitiveness, and new business expansion plans.
    What are the Risks?
    Investors should consider potential risks such as global economic uncertainties, semiconductor industry fluctuations, and changes in exchange rates and interest rates. Continued underperformance in the display evaluation equipment segment also warrants attention.

    What is Techwing’s main business?

    Techwing manufactures semiconductor back-end test handlers, HBM testing equipment, and display inspection equipment. They are particularly recognized as a beneficiary of the increasing demand for HBM testing equipment driven by AI market growth.

    What does an after-hours block trade signify?

    An after-hours block trade refers to a large-volume transaction of shares outside of regular trading hours. It can indicate deliberate buying or selling activity by specific investors and may significantly impact stock prices.

    What should investors consider when investing in Techwing?

    Investors should consider macroeconomic factors like global economic uncertainties, fluctuations in the semiconductor industry, and exchange rate/interest rate changes. The potential for continued underperformance in the display evaluation equipment sector should also be monitored.

  • Opticore’s After-Hours Trading Surge: Analyzing the Impact and Future Outlook

    1. What Happened?

    On August 22nd, Opticore saw significant after-hours trading activity. A large buy order of ₩1.1 billion from an institutional investor was recorded, alongside a smaller sell order from foreign investors totaling ₩0.08 billion. A total of 762,185 shares were traded.

    2. Why Did This Happen?

    Opticore reported declining sales and a shift to negative earnings in the first half of 2025. This was attributed to the slowdown in 5G investments and subsequent weaker demand for optical transceivers. However, Opticore is pursuing growth strategies, including developing high-speed optical transceivers for data centers in the AI era, expanding into overseas markets, and diversifying its business. The large institutional buy order could indicate a positive outlook on these growth strategies.

    3. What’s Next?

    The institutional buy order is expected to positively impact short-term supply and demand dynamics, potentially supporting Opticore’s stock price. It could also improve investor sentiment. However, increased price volatility is possible depending on market reactions in the following trading sessions.

    4. What Should Investors Do?

    Investors should carefully evaluate Opticore’s long-term growth potential rather than focusing solely on short-term price fluctuations. Key factors to monitor include the performance of new businesses, success in overseas market expansion, and management of financial health. Further changes in shareholding patterns should also be observed. While the after-hours trading activity might be a positive sign, sustainable stock price growth depends on fundamental improvements and the successful execution of growth strategies.
