KOSPI Index Hits New Highs: Fresh Investment Opportunities in South Korea’s Stock Market

KOSPI index hits a new high

As of September 18, 2025, the KOSPI index in South Korea reached 3,449.37 points, setting a new historical record. It has risen over 38% year-to-date, leading the performance in the Asian market. This round of growth is mainly attributed to the expansion of industries such as semiconductors, technology, and new energy vehicles, as well as the trend of global capital inflows.

Market sentiment is optimistic, but investors still need to pay attention to short-term fluctuations, especially under the influence of global macroeconomic uncertainty and the Federal Reserve’s interest rate policies, where indices may experience volatility.

The policy environment boosts the market.

President Lee Jae-myung has postponed the capital gains tax reform, especially the policies related to the tax burden on major shareholders, injecting confidence into the market. Investors are no longer overly concerned about short-term tax increases, and the inflow of funds into the market has significantly improved. At the same time, the government continues to promote corporate transparency and corporate governance reforms, which helps to enhance the trust of long-term investors.

In addition, policy support is reflected not only in tax aspects but also includes support for innovative industries, green energy subsidies, and technology development plans, promoting stable performance of stock prices in related industries.

Discount phenomenon and investment opportunities

The South Korean stock market has long experienced a “discount” phenomenon, where corporate valuations are lower than those of global peers. Reform measures are expected to narrow this gap and provide structural opportunities for investors. In the long run, as company profits and dividend policies improve, market valuations may gradually recover.

Investors can take advantage of the discount phenomenon to select individual stocks with growth potential and stable returns, especially leading companies in policy-supported industries.

Investment Strategies and Industry Trends

• Semiconductor and technology industry: Global demand growth and technological upgrades are driving the market value increase of related companies.
• New Energy Vehicles and Green Energy: Policy support and market expansion create a double benefit.
• Consumer Goods and Services Industry: The recovery of domestic demand and consumption upgrade bring steady growth.
• High dividend blue-chip stocks: providing robust cash flow returns amidst market volatility.
• Pay attention to policy changes: adjust your investment portfolio in a timely manner to respond to changes in tax and corporate governance policies.

Market Risks and Investment Recommendations

• Short-term volatility risk: Global macroeconomic factors, international capital flows, and policy adjustments may trigger short-term market fluctuations.
• Industry concentration risk: Over-concentration in a certain industry may increase investment risk, and investments should be diversified.
• Policy uncertainty: Future changes in tax, capital control, and corporate reform policies may affect stock market performance.

Conclusion: The potential of long-term investment in the South Korean stock market.

In 2025, the KOSPI index reached new highs repeatedly, demonstrating the market’s growth potential and the positive effects of policies. Investors have the opportunity to achieve long-term stable returns in the Korean stock market by focusing on industries benefiting from reforms, diversifying investments, and reasonably allocating high dividend stocks. Although short-term fluctuations still exist, from a structural opportunity perspective, the Korean stock market remains worthy of attention.
