1. What Happened? After-Hours Block Trade Analysis

Before the market opened on August 6, 2025, a large block trade of KRW 36.8 billion, totaling 618,180 shares, occurred in SNT Dynamics. Foreign investors net bought KRW 1.8 billion, while other financial investors net sold KRW 33 billion. Such large transactions can cause short-term volatility in stock prices.

2. Why Did This Happen? Fundamental Analysis

SNT Dynamics demonstrated solid fundamentals by announcing strong earnings in Q1 2025. Sales increased by 31.6% year-on-year and operating profit surged by 60.9% due to increased exports in the transportation equipment business. Steady growth in the defense sector and strengthened global partnerships are expected to act as future growth drivers. However, increasing inventories and exchange rate volatility are factors to watch.

3. So What Happens Next? Investment Strategy

While after-hours block trades can cause short-term stock price fluctuations, SNT Dynamics’ solid fundamentals and growth momentum remain valid. The large sell-off by other financial investors is likely profit-taking, while foreign buying can be interpreted as a positive signal. Investors should focus on analyzing the company’s value from a long-term perspective rather than reacting emotionally to short-term supply and demand fluctuations.

4. Action Plan for Investors

  • Focus on long-term growth potential but be mindful of short-term volatility.
  • Monitor the continued growth of the defense and automotive parts businesses.
  • Monitor inventory management efficiency and cost management strategies.
  • Continuously observe the volatility of macroeconomic indicators (exchange rates, interest rates, raw materials).
