On the 1st, the first trading day of June, the domestic stock market showed a strong upward trend. As the KOSPI surged more than 3%, large-cap tech stocks, LG Group stocks, and internet stocks jointly gained strength, significantly boosting investor sentiment.

As of the morning of the 1st, the KOSPI index recorded 1384.55, up 41.75 points (3.11%) from the previous trading day. The KOSDAQ index also continued its upward trend, trading at 1060.11, up 14.69 points (1.37%), while the KRX100 index rose 3.12%, unfolding a bull market centered on large-cap stocks.

In the market that day, Samsung Electronics and LG Electronics led the index's rise. Samsung Electronics surged 7.10% to 339,500 won, showing the strongest trend among the top stocks by market capitalization, and its trading volume exceeded 26 million shares, indicating an inflow of massive buying interest. LG Electronics soared as much as 26.45% to 370,500 won, and LG also surged 17.05%, leading a strong revaluation trend across group stocks in general. Reflecting expectations for the expansion of the AI industry and the growth of digital platforms, NAVER also recorded a 11.11% increase to 260,000 won.

The automobile and financial sectors also showed solid performance. Hyundai Motor recorded a 3.32% increase to 747,000 won, and Kia also maintained its upward trend, but Hyundai Mobis fell by more than 2%, showing differentiation among individual stocks. In the financial sector, KB Financial (1.46%), Shinhan Financial Group (1.07%), and Samsung Life Insurance (1.42%) rose slightly, while Samsung Fire & Marine Insurance surged 6.68%, leading the strength in insurance stocks.

In the semiconductor sector, while Samsung Electronics surged, SK Hynix remained flat. Samsung Electro-Mechanics fell 2.21% due to the impact of profit-taking sell-offs. In the KOSDAQ market, POSCO DX surged 11.86%, and Seoul Semiconductor also rose 6.44%, reflecting expectations related to optical semiconductors. Kakao (1.55%) and Deoksanshimetal also showed an upward trend. On the other hand, the secondary battery sector was relatively sluggish, with Samsung SDI and POSCO Future M falling by 4.51% and 3.87%, respectively.

Analyses in the market suggest that investor preference for risk assets is recovering as tensions surrounding the United States and Iran enter a phase of de-escalation. In addition, expectations for growth industries such as AI, power infrastructure, robotics, and semiconductors are adding to the expansion of buying interest. The securities industry believes that if the strong performance of top market capitalization growth stocks like Samsung Electronics, LG Electronics, and NAVER continues, it could serve as an additional upside driver for the KOSPI. However, they also pointed out that with the recent increase in stocks that have surged rapidly, attention must also be paid to the possibility of expanded volatility due to short-term profit-taking sell-offs.
