Today Korean Economic News | 2025.03.15

📌 KOSPI Closes at 2,560 Range with Slight Decline for Second Consecutive Day... KOSDAQ Up 1.6%

💬 KOSPI closed at 2,566.36 on the 14th, down 7.28 points (0.28%) from the previous day, showing a slight decline for the second consecutive day. In contrast, the KOSDAQ index recorded 734.26, up 11.46 points (1.59%).

SK Hynix rose 2.40%, recovering to the 200,000 won range on expectations of a semiconductor industry recovery.

1️⃣ Easy to Understand

KOSPI and KOSDAQ are showing different patterns. While KOSPI slightly declined, KOSDAQ rose by nearly 1.6%. I'll explain why this happened and what it means in simple terms.

KOSPI and KOSDAQ are like two different markets. KOSPI is the 'main market' where major companies like Samsung Electronics, Hyundai Motor, and SK Hynix are listed, while KOSDAQ can be seen as a 'second league' of relatively smaller but high-growth potential small and venture businesses.

There are three main reasons why KOSPI showed weakness this time. First, concerns about a trade war have increased as the U.S. announced new tariff impositions. This could negatively affect Korean large companies that are highly dependent on exports. Second, the possibility of a U.S. federal government shutdown has raised global economic uncertainty. Third, the domestic political situation has also led investors to take a wait-and-see approach.

On the other hand, KOSDAQ's strength is related to the recent increased interest in technology and growth stocks. In particular, as expectations for semiconductor industry recovery have grown, the stock prices of semiconductor-related small companies have risen. SK Hynix also rose 2.4% to recover to the 200,000 won range, showing positive momentum for the entire semiconductor industry.

An interesting point is the behavior of foreign investors. They sold about 280 billion won worth of stocks in KOSPI but bought about 200 billion won worth in KOSDAQ. This can be seen as a signal that foreigners are more interested in small companies with growth potential than in large companies.

This phenomenon shows a change in investment trends. It reflects the market's judgment that while large companies may struggle in an uncertain global environment, small companies with technological capabilities might actually seize opportunities. Investors now seem to be considering future growth potential and innovation capacity more importantly than simply 'large companies'.

2️⃣ Economic Terms

📕 KOSPI

KOSPI is a stock price index and the representative indicator of the Korean stock market, showing value changes of major companies.

• It consists mainly of large companies listed on the Korea Exchange and is calculated using a market capitalization weighted method.
• It fluctuates due to various factors such as economic conditions, corporate performance, and investment sentiment, and is used as an indicator to gauge the soundness of the national economy.

📕 KOSDAQ

KOSDAQ is a market centered on venture and small businesses, with high-growth companies listed.

• Established in 1996 modeled after the U.S. NASDAQ, it has many companies in new growth industries such as IT, biotech, and entertainment.
• It has greater volatility compared to KOSPI and is characterized by growth-oriented investments.

📕 Net Purchase (Net Selling)

Net purchase refers to the value obtained by subtracting the sales volume from the purchase volume; if the net purchase is positive, it means more was bought.

• Conversely, net selling means that the sales volume is greater than the purchase volume.
• Investor-specific (individual, foreign, institutional) net purchase trends are important indicators for understanding market fund flows and investment sentiment.

📕 Tariffs

Tariffs are taxes imposed on imported goods that affect trade relations between countries and the global economy.

• They are used for purposes such as protecting domestic industries, adjusting trade balances, and securing fiscal revenues.
• Tariff rate increases lead to higher import prices, affecting consumer prices and companies' cost structures.

3️⃣ Principles and Economic Outlook

💡 Differentiation Phenomenon between KOSPI and KOSDAQ and Its Background

• Several structural and cyclical factors are at play in the differentiation phenomenon where KOSPI and KOSDAQ move in different directions.

  • First, global uncertainties have different impacts on large companies and small businesses. The U.S.'s strengthened tariff policies and deepening trade conflicts can directly hit large companies listed on KOSPI that are highly dependent on exports. In particular, companies in traditional manufacturing fields such as automobiles, steel, and chemicals are expected to be greatly affected. In contrast, KOSDAQ companies often have relatively higher domestic demand proportions or are specialized in niche markets, so the direct impact of global trade conflicts may be limited.

  • Second, expectations for semiconductor industry recovery are affecting markets differently. Semiconductor industry improvement is positive for large-cap stocks like Samsung Electronics and SK Hynix, but it also acts as a boon for small companies listed on KOSDAQ that supply related equipment, materials, and components. Especially with the AI boom, small companies with specialized technologies are gaining attention, and their growth potential is being re-evaluated by the market. SK Hynix's stock price recovery served as a signal showing positive momentum for the entire semiconductor industry.

  • Third, changes in investor composition and fund flows are important factors. The phenomenon where foreign investors net sold in KOSPI but net purchased in KOSDAQ is noteworthy. This can be seen as reflecting the global investment trend where foreigners are more interested in innovative companies with growth potential than large export stocks. In particular, as investments in future growth industries such as biotech, IT, and content are expanding, the KOSDAQ market, where many such companies are listed, is benefiting.

  • Fourth, there are also differences in terms of valuation and investment sentiment. The KOSPI market is in a state of relatively low valuation compared to the global situation, but investors are continuing to take a wait-and-see approach amid uncertainty about immediate performance improvement. On the other hand, in the KOSDAQ market, investment focusing on future growth potential is taking place, forming an investment pattern that places more weight on growth stories than current performance.

• This differentiation phenomenon can be seen as an important signal reflecting not only short-term market fluctuations but also changes in the Korean economy and industrial structure, and the changing position of Korean companies in the global economic environment. In particular, it suggests the possibility of a transition from the traditional large company-centered growth model to a more diverse and dynamic economic structure led by innovative small businesses and startups.

💡 Changes in Foreign Investors' Investment Patterns and Their Significance

• The phenomenon of foreign investors net selling in KOSPI while net purchasing in KOSDAQ shows a change in global investment trends.

  • First, portfolio restructuring is taking place among foreign investors within the Korean market. In the past, foreigners mainly invested in large-cap stocks such as Samsung Electronics, Hyundai Motor, and SK Hynix, but recently, interest in small and mid-cap stocks with high growth has increased. In particular, investments are expanding in KOSDAQ companies specialized in future growth industries such as AI, biotech, content, and secondary batteries. This can be interpreted as part of a strategy seeking high returns through preemptive investment in innovative companies based on experiences in the global market.

  • Second, risk management strategies are changing amid global uncertainties. Amid various uncertainty factors such as U.S.-China trade tensions, changes in global interest rate policies, and geopolitical risks, foreigners are showing a tendency to prefer companies that have a high proportion of domestic demand or competitiveness with specialized technology, which are relatively less sensitive to external shocks, rather than large export stocks. This can be seen as a strategic approach to diversify risks while not missing growth opportunities from a global portfolio perspective.

  • Third, the global perception of Korean small businesses is changing. In the past, Korean small businesses had low investment attractiveness to foreign investors due to information asymmetry and governance opacity, but perception is improving recently due to corporate governance improvement, increased information disclosure, and increased cases of successful global market entry. In particular, as some KOSDAQ companies gain recognition for their unique technological prowess and competitiveness in the global market, foreigners' investment sentiment is also changing positively.

  • Fourth, there are also differences in attractiveness from a valuation perspective. Recently, the KOSPI market is in a state of low valuation compared to the global market, but visibility for performance improvement is limited. On the other hand, some KOSDAQ companies are being evaluated as having high investment attractiveness due to rapid growth and innovation possibilities, even if their valuations are relatively high. Foreigners seem to be willing to pay a premium for growth, recognizing these differences.

• These changes in foreign investment patterns may signify a fundamental change in the global perspective on the Korean stock market and companies beyond a simple short-term trend. This can be interpreted as a positive signal that the Korean economy can evolve from the traditional large company-centered model to a more balanced structure where innovative small businesses grow together.

💡 Future Stock Market Outlook and Investment Strategy Implications

• The differentiation between KOSPI and KOSDAQ and changes in foreign investment patterns provide important implications for future stock market outlooks and investment strategies.

  • First, global uncertainties and domestic political situations are factors that increase short-term volatility. The U.S.'s strengthened tariff policies, the possibility of a federal government shutdown, and political uncertainties in Korea are expected to act as factors limiting market directionality for the time being. In particular, large manufacturers with high export dependence are likely to react more sensitively to these uncertainties. Investors may want to maintain conservative positions in the short term while closely monitoring the development of these external variables.

  • Second, differentiation by industry and company is expected to become more pronounced. Positive momentum in specific industries such as semiconductor industry recovery, AI technology development, and biotech innovation will act as a boon for companies in those fields. On the other hand, traditional manufacturing or domestic consumer goods may struggle due to concerns about economic recession and weakened consumer sentiment. It's time for investors to take a selective investment approach by analyzing industry trends and individual company competitiveness more meticulously.

  • Third, interest in innovative companies and growth stocks is expected to continue from a mid- to long-term perspective. Foreign investors' net purchase in KOSDAQ is part of this trend, and small and mid-cap companies with technological prowess and global competitiveness are likely to receive attention. The premium for companies specialized in future growth industries such as digital transformation, eco-friendly energy, biohealth, and content is expected to continue. However, caution should also be exercised regarding the possibility of bubble formation due to excessive expectations.

  • Fourth, the possibility of rotation between large-cap and small- and mid-cap stocks should also be considered. Currently, attention is focused on innovative companies and growth stocks, but if global uncertainties ease and expectations for economic recovery grow, fund movement to large cyclical stocks or value stocks may occur. Especially if the relative undervaluation of the KOSPI market persists, strategic allocation to large-cap stocks should be considered at an appropriate time.

  • Fifth, market impacts according to changes in global monetary policy should be monitored. The timing and speed of the Fed's interest rate cuts, and the policy direction of the Bank of Korea in response, will greatly affect market liquidity and investment sentiment. If the interest rate cut cycle intensifies, risk asset preference sentiment may strengthen, positively affecting the overall stock market. On the other hand, if interest rate cuts are delayed due to inflation concerns, there is a possibility of an adjustment centered on growth stocks.

• Considering these various factors, the future stock market is expected to show a complex pattern where global uncertainties and industry-specific differentiation coexist. Investors should closely monitor the development of domestic and foreign variables and take a selective investment approach centered on industries and companies with structural growth possibilities from a mid- to long-term perspective.

4️⃣ In Conclusion

The current situation where KOSPI and KOSDAQ show different movements reflects changes in the Korean stock market and economic structure. While concerns about a U.S.-originated tariff war, the possibility of a federal government shutdown, and domestic political uncertainties weighed on the large-cap-centered KOSPI, expectations for semiconductor industry recovery and increased interest in innovative companies acted as positive factors for the KOSDAQ market.

Particularly noteworthy is the change in foreign investors' behavior. Recording net selling in KOSPI while net purchasing in KOSDAQ shows changes in global investment trends and improved perception of Korean small businesses. This can be interpreted as a positive signal that the Korean economy can evolve from the traditional large company-centered model to a more balanced structure where innovative small businesses grow together.

SK Hynix rising 2.40% to recover to the 200,000 won range reflects expectations for semiconductor industry recovery. This can act as positive momentum not only for that company but also for the related ecosystem as a whole. It particularly acts as a boon for small businesses supplying semiconductor equipment, materials, and components, many of which are listed on KOSDAQ, which became the driving force behind KOSDAQ's rise.

The future stock market is expected to show a complex pattern where global uncertainties and industry-specific differentiation coexist. External variables such as U.S. tariff policies, the possibility of a federal government shutdown, and changes in global monetary policy, along with domestic political situations and economic trends, will act as important variables. In particular, as differentiation by industry and company becomes more pronounced, selective investment through detailed analysis will become more important than blindly following the market.

In conclusion, the current market situation can be seen as a transitional phase where challenges and opportunities coexist. It's a time when discernment to discover industries and companies with structural growth possibilities in the mid to long term is important, while preparing for short-term volatility and uncertainty. In particular, it is necessary to maintain interest in innovative companies with global competitiveness while employing flexible asset allocation strategies according to market environment changes.
