Market Briefing: KOSPI 8,600선 돌파와 반도체 쏠림 현상
The KOSPI has surpassed the 8,600 mark, hitting record highs, but the gains are heavily concentrated in chipmakers like Samsung Electronics and SK hynix. Excluding semiconductors, the index would realistically sit between 4,100 and 4,200.
Daily Stock Market Briefing — 2026-06-02
Major Market Issues
1. KOSPI hits record highs amid semiconductor concentration The KOSPI crossed the 8,600 mark yesterday, continuing to set new record highs. However, the growth is heavily focused on major semiconductor stocks like Samsung Electronics and SK hynix. Excluding the chip sector, the effective KOSPI index would be in the 4,100–4,200 range, raising concerns about extreme market polarization.
2. Trading volume dominated by semiconductors and secondary batteries As of May 31, top-traded stocks include semiconductors like SK hynix, Samsung Electronics, and Samsung Electro-Mechanics, while leveraged products (KODEX Leverage) also maintain high trading volumes.
3. Influence of the AI semiconductor rally in the US The surge in semiconductor and related companies in the U.S. market, driven by demand for AI data centers and servers, is the primary driver behind the gains in domestic chip stocks.
Hot Themes and Key Movers
1. Semiconductor Theme
- SK hynix, Samsung Electronics, Samsung Electro-Mechanics: These stocks are leading in trading volume, benefiting from the robust chip market sparked by rising U.S. AI data center demand.
2. Secondary Battery Theme
- Samsung SDI, L&F, Hanchang Nasec: These are seeing gains due to increased demand for AI data centers and Energy Storage Systems (ESS). Experts are generally recommending maintaining existing positions rather than entering the market at this level.
3. KOSDAQ upward trend
- Jusung Engineering: Surged 9.88%
- EcoPro BM: Rose 5.64%
- EcoPro: Rose 4.62%
- Bio stocks: Strong performance from Alteogen (3.27%), Kolon TissueGene (3.30%), and HLB (5.56%).
Macro Context
1. Ripple effects of the global AI semiconductor rally Strong demand for AI servers and data centers in the U.S. is pushing domestic semiconductor stocks higher, supported by solid fundamentals, including Capital Expenditures (Capex) and improved earnings from Big Tech firms.
2. KOSPI index distortion Because semiconductor stocks make up such a large portion of the KOSPI’s market cap, there is a growing gap between the headline index growth and the actual sentiment across the broader market. Recovery in other industries is needed.
3. Balanced growth in KOSDAQ Unlike the KOSPI, the KOSDAQ shows more balanced growth across various sectors—including semiconductors, secondary batteries, and biotech—suggesting better industrial diversification.
