Domestic Market Closing Brief and AI Investment Ideas — 2026-06-02
Market Closing Status
- KOSPI Index: Broke through the 8600 level, hitting new all-time highs consecutively.

Today’s Notable Stocks and Key Issues
SK Hynix & Samsung Electronics (Semiconductor Leadership) Semiconductor stocks continue to lead the market, capturing the top spots in trading volume. SK Hynix closed at 2,333,000 won, driving the market's gains, while Samsung Electronics maintains strong momentum. However, the heavy concentration in this sector is limiting broader market synchronization.
Increased Investment in AI & Robotics Startups As the domestic startup investment market shows signs of recovery, large-scale capital is being concentrated in AI and robotics, particularly in teams led by proven researchers. A clear trend of "selection and concentration" is emerging, with seed-stage investments now reaching as high as 10 billion won.
AI-Driven Investment Ideas
1. Leveraging Semiconductor Capex Trends U.S. and Korean markets are moving on the back of solid fundamentals: Big Tech and semiconductor earnings growth. The sustainability of the current Capex cycle will be a key investment point moving forward.
2. AI Data Centers and ESS-Related Secondary Battery Stocks AI data centers and Energy Storage Systems (ESS) are expected to be the center of secondary battery momentum, with companies like Samsung SDI, L&F, and HanJoongNCS drawing investor attention.
3. Potential IPOs for Proven AI & Robotics Startups Since AI and robotics startups led by verified research teams are successfully raising significant capital, they are likely to emerge as prime candidates for future IPOs.
Investment Precautions & Macro Context
1. Need for Diversification Due to Semiconductor Concentration Because the KOSPI rally is centered around semiconductor stocks, broader market synchronization is hindered. Diversifying your portfolio is recommended to hedge against potential sector rotation.
2. Global Political Uncertainty Discussions regarding a ceasefire between the U.S. and Iran are underway, and these geopolitical variables could influence future market volatility.
3. Changes in National Pension Service (NPS) Flows The market has responded positively to the removal of "NPS selling bombs," but future inflow/outflow trends from institutional and foreign investors remain a key area for monitoring.
