Domestic Stock Market Rebounds After Three Days... Semiconductor Stocks Uncertainty Resolved

KOSPI Rises Over 1.5% to Recover to 2440 Level

The domestic stock market rebounded on the 23rd after three days, driven by bargain buying from foreigners and institutions. The KOSPI rose more than 1.5% to recover to the 2440 level, while the KOSDAQ increased by 1.6%, approaching the 680 level.

On that day, the KOSPI index closed at 2442.01, up 1.57% from the previous session. The index started at 2423.36, up 0.8%, and extended its gains during the session to rise into the 2440 range.

By trading participant, foreigners and institutions led the buying with 145.4 billion KRW and 433.7 billion KRW respectively, driving the index higher. In contrast, individual investors showed a net selling of 677.5 billion KRW.

Among individual stocks, semiconductor shares such as Samsung Electronics (0.94%), SK Hynix (0.65%), and Hanmi Semiconductor (8.65%) rose together. This was influenced by the final confirmation of investment subsidies from the U.S. government to Samsung Electronics and SK Hynix, resolving uncertainties. It also appears that Broadcom’s request to these two companies to supply the next-generation high-bandwidth memory (HBM) product, HBM4, contributed to the positive sentiment.

Shipbuilding stocks expected to benefit from the U.S. policy to strengthen shipbuilding capabilities also rose together, including HJ Heavy Industries (13.85%), Hanwha Ocean (7.04%), and HD Hyundai Heavy Industries (8.24%). LG Energy Solution rose 0.42%, while NAVER (-4.29%) and Kakao (-2.70%), which had shown notable recent gains, weakened due to profit-taking selling.

By sector, most sectors rose except for Information Technology (IT) Services (-1.90%) and Transportation & Warehousing (-0.12%). Notable gains were seen in Metals (4.69%), Machinery & Equipment (3.25%), and Insurance (3.50%).

Meanwhile, the KOSDAQ index also rebounded after three trading days, closing at 679.24, up 1.64% from the previous session. The index opened at 674.26, up 0.89%, then extended gains during the session, reaching as high as 683.16, up 2.22% intraday.

In the KOSDAQ market, foreigners and institutions were net buyers of 131.1 billion KRW and 109.1 billion KRW respectively, while individuals showed net selling of 233.6 billion KRW.

Among the top market cap stocks, many rose including EcoPro BM (0.61%) and Rigachem Bio (4.06%), while HLB (-2.87%) and EcoPro (-0.94%) declined. Alteogen remained flat.
