The KOSPI and KOSDAQ indices closed higher.
On the 30th, the KOSPI closed at 2453.16, up 0.38% (9.24 points) from the previous trading day. The KOSPI opened at 2452.97, up 0.38% (9.05 points) from the previous day, showing mixed movements with repeated rises and falls throughout the session. However, as foreign investors engaged in net buying of both spot and futures, the market ended on an upward trend. Foreign investors purchased stocks worth 262.5 billion KRW in the spot market and 835.2 billion KRW in the futures market. Meanwhile, individual and institutional investors sold stocks worth 120.3 billion KRW and 142.5 billion KRW, respectively.
The rise in the index was driven by semiconductor stocks. The previous day, Micron surged more than 7% on positive news of inventory reduction, which had a favorable impact. Expectations of a bottoming out in the memory semiconductor market were also reflected. Samsung Electronics rose 0.8%, and SK Hynix increased by 2.19%.
However, it was insufficient to surpass the high point recorded this month (2475 points). Lee Kyung-min, a researcher at Daishin Securities, said, “The 12-month forward price-to-earnings ratio (PER) has risen to 13 times, increasing valuation pressure, which remains a burden. Also, the excessive expectations for monetary policy in the financial market still persist, limiting the market’s resilient rise.”
A notable stock was SK Innovation. SK Innovation surged more than 13% on plans for shareholder return policies, including a public tender offer and dividend increases. Among other large-cap stocks, LG Energy Solution (0.86%), Hyundai Motor (0.44%), and NAVER (0.95%) rose, while Samsung Biologics (-1.14%), Samsung SDI (-1.28%), and Kia (-0.13%) declined.
On the same day, the KOSDAQ index rose nearly 1%, reaching an intraday high of 852.59. The index closed at 850.48, up 0.77% (6.54 points). Regarding investment trends, individual and institutional investors bought stocks worth 122.4 billion KRW and 19 billion KRW, respectively, while foreign investors sold stocks worth 121.2 billion KRW alone.
By sector, the rise in large semiconductor stocks led to notable gains in materials, parts, and equipment-related stocks. By individual stocks, Intecplus (11.7%), Nepes (8.7%), SFA Semiconductor (8.3%), and Symtek (7.4%) rose.
Among the top market capitalization stocks, L&F (2.6%), HLB (1.37%), Kakao Games (0.49%), and JYP Ent. (0.39%) increased, while EcoPro BM (-2.79%), Celltrion Healthcare (-0.17%), Celltrion Pharm (-0.97%), Pearl Abyss (-1.07%), and Osstem Implant (-0.05%) declined.
