    Seojin System Announces ₩10 Billion Stock Buyback: A Sign of Recovery? 대표 차트 이미지



    1. Seojin System’s Stock Buyback: What’s Happening?

    Seojin System announced on September 24th its decision to repurchase and retire ₩10 billion worth of its own shares. A total of 449,438 shares will be acquired through on-market purchases facilitated by Yuanta Securities.

    2. Why the Buyback?

    The official objective is to ‘enhance shareholder value’. By reducing the number of outstanding shares through repurchasing and retiring stock, Seojin System aims to increase earnings per share (EPS) and book value per share (BPS), potentially leading to a rise in stock price. It also sends a positive signal to investors amidst difficult market conditions and demonstrates a commitment to defending the stock price.

    3. Potential Impact of the Buyback

    • Positive Impacts: Potential stock price boost, enhanced shareholder value, improved investor sentiment.
    • Negative Impacts: Increased financial burden due to the ₩10 billion expenditure, difficulty in securing long-term stock price growth without fundamental business improvements.

    The key lies in ‘fundamental business improvement’. Seojin System currently faces challenges such as declining sales, net losses, and increasing debt ratios. While the buyback may offer a short-term boost to the stock price, long-term growth necessitates fundamental management improvements, including the recovery of the ESS business and successful development of new businesses.

    4. What Should Investors Do?

    While the stock buyback can be a short-term positive factor, investors should remember that ‘all investment decisions and their consequences are the investor’s responsibility’. Instead of being swayed by short-term stock price fluctuations, it’s crucial to make informed investment decisions based on a comprehensive consideration of Seojin System’s mid-to-long-term business outlook, financial status, and market conditions.



    FAQ

    What is Seojin System’s current financial status?

    Based on the 2025 semi-annual report, they are facing challenges such as declining sales, net loss, and increasing debt ratio. However, they are striving to improve their financial structure and secure future growth engines through active fundraising and new business development.

  • SAMCNS Designated as Overheated Stock: Investment Strategies?





    What’s Happening with SAMCNS?

    On September 23, 2025, SAMCNS was designated as an overheated stock by the Korea Exchange. This indicates that the stock price has experienced rapid increases over the past three trading days, showing signs of speculative overheating. As a result, SAMCNS will be traded under a single-price trading method for three days, a measure designed to limit price volatility and encourage cautious investment.

    Why the Overheating?

    The surge in SAMCNS’s stock price is attributed to the combined effect of positive expectations for growth in the HBM (High Bandwidth Memory) market and the company’s strong performance in the first half of 2025. With a high proportion of ceramic STF for NAND probe cards and improved profitability efforts, SAMCNS recorded sales of KRW 34.5 billion (YoY +41.1%) and operating profit of KRW 4.9 billion (YoY +34.0%) in Q2 2025. The development and expansion of ceramic substrates for HBM are particularly anticipated as key growth drivers for the company.

    Implications of the Overheated Stock Designation

    • Increased Short-Term Volatility: The designation serves as a warning signal, potentially leading to investor anxiety and profit-taking, thus increasing price volatility.
    • Reduced Trading Volume and Volatility: The single-price trading method restricts trading volume and price fluctuations, potentially hindering price discovery in the short term.
    • Limited Impact on Fundamentals: The designation itself does not necessarily undermine the company’s intrinsic value.

    Investor Action Plan

    • Short-Term Investors: Proceed with caution, considering the potential for profit-taking and increased selling pressure.
    • Long-Term Investors: Continuously monitor the company’s fundamentals and competitiveness in the HBM market, potentially using price fluctuations as opportunities for staggered purchases.


    FAQ

    What does it mean to be designated as an overheated stock?

    It’s a regulatory measure to curb speculative trading in stocks that have experienced excessive price increases in a short period. Designated stocks are traded under a single-price trading method for a specific duration.

    What is single-price trading?

    It’s a trading method where orders are collected and executed at a single price at a designated time. It limits price fluctuations, mitigating sharp rises and falls.

    What is the outlook for SAMCNS?

    While SAMCNS has a strong growth driver in the expanding HBM market, short-term price volatility may increase. Long-term investors should monitor the company’s performance in the HBM market and its technological competitiveness.

    Surplus Global Announces Treasury Stock Disposal: Impact on Stock Price and Investment Strategy 대표 차트 이미지

    1. What Happened? : Decoding the Treasury Stock Disposal

    On September 23, 2025, Surplus Global announced its decision to dispose of 2,160,000 common shares, representing 5.84% of its total outstanding shares. This equates to approximately 6.5 billion won and aims to secure funds for issuing exchangeable bonds (EB).

    2. Why This Decision? : Uncovering the Background and Implications

    Surplus Global is currently facing financial challenges, including declining sales, operating losses, and weakened cash flow. In this context, the decision to raise capital through treasury stock disposal is interpreted as a necessary step to secure short-term liquidity and fund new business ventures. The company appears to be prioritizing investment in new growth engines such as the used semiconductor equipment parts business and the establishment of a global marketplace.

    3. So, What About the Stock Price? : Market Impact Analysis

    • Positive Aspects: Securing short-term liquidity and the potential for growth momentum through new business investments.
    • Negative Aspects: Potential stock dilution from EB issuance and the possibility of continued struggles in existing businesses.

    Ultimately, this treasury stock disposal could have both positive and negative short-term impacts on the stock price. The key lies in how effectively the raised funds are utilized. Successful new business ventures and financial restructuring could act as catalysts for stock price appreciation. Conversely, failure to achieve these goals could exacerbate downward pressure on the stock.

    4. What Should Investors Do? : Investment Strategy Recommendations

    Investors should closely monitor the following:

    • Terms and outcome of the EB issuance
    • Specific use and execution of the raised funds
    • Performance of new businesses and recovery of existing businesses
    • Overall market conditions and macroeconomic indicator changes

    It’s crucial to focus on the company’s long-term growth potential rather than short-term stock price volatility when making investment decisions. Investment strategies should be formulated based on careful analysis and prudent judgment.

    Frequently Asked Questions

    What is treasury stock disposal?

    Treasury stock disposal refers to a company selling its own repurchased shares back into the market. This can be done to increase the value of remaining shares by reducing the number outstanding or to raise capital.

    What are exchangeable bonds (EB)?

    Exchangeable bonds are bonds that give the holder the right to exchange them for shares of a company other than the issuer, or for another asset. Investors receive interest payments until maturity and have the option to exchange the bonds for stock, potentially profiting from price appreciation.

    What is the outlook for Surplus Global’s stock price?

    Raising capital through treasury stock disposal can have both positive and negative effects on the stock price in the short term. The success of new business ventures and financial restructuring will be key factors in determining the stock’s direction.

    Surplus Global Issues ₩6.5B Convertible Bonds: A Strategic Move or a Desperate Gamble? 대표 차트 이미지






    1. What Happened at Surplus Global?

    2. Why Issue Convertible Bonds?

    Surplus Global’s performance in the first half of 2025 was weak. Sales decreased by 58.8% year-on-year, and both operating income and net income turned to losses. The high debt ratio and increasing inventory levels raise concerns about financial soundness. In this situation, issuing convertible bonds appears to be an inevitable choice to secure short-term working capital and raise funds for new business investments.

    3. Convertible Bonds: Opportunity or Risk?

    • Positive Aspects:
      • Securing short-term liquidity.
      • Potential for securing growth engines through investment in new businesses.
    • Negative Aspects:
      • Increased financial burden due to a higher debt ratio.
      • Pressure on stock price due to the high conversion price compared to the current market price.
      • Risk of future interest rate hikes and exchange rate fluctuations.

    4. What Should Investors Do?

    While the issuance of convertible bonds can provide a short-term cash injection, long-term growth cannot be guaranteed without fundamental improvements in business competitiveness. Investors should carefully monitor the following:

    • Conversion of convertible bonds.
    • Performance of new businesses (used semiconductor equipment cluster, global open market).
    • Recovery trend of the semiconductor market.
    • Future profitability improvement.

    Currently, it is advisable to maintain a cautious wait-and-see approach and take a conservative perspective, considering the additional financial burden and the high conversion price.



    FAQ

    What are convertible bonds?

    Convertible bonds are bonds that give the holder the right to convert them into shares of the issuing company’s stock. Investors can hold the bonds to maturity and receive principal and interest, or they can convert them into stock within a specified period.

    How will this convertible bond issuance affect Surplus Global’s stock price?

    In the short term, it could be positive due to increased liquidity. However, in the long term, there is the possibility of stock dilution due to bond conversion. The company’s earnings improvement will likely have a greater impact on the stock price.

    What should investors be aware of?

    It’s important to consider the company’s financial restructuring efforts, the performance of new businesses, and the overall semiconductor market conditions when making investment decisions.

    5. What Should Investors Do? (Action Plan)

    This investment by VIP Asset Management can positively impact stock prices in the short term, but caution is needed from a mid- to long-term investment perspective. It is crucial to make investment decisions by closely monitoring Wonik Materials’ earnings improvement and market conditions.
