The Korea Composite Stock Price Index (KOSPI) is trading around the 4,150 mark on the 12th, up about 1%. Following Broadcom's surprise earnings report, investment sentiment across the AI Value Chain has improved, prompting institutions to make net purchases exceeding 1 trillion won and driving the index higher.
As of 2:20 p.m., the KOSPI was trading at 4,154.03, up 1.06% from the previous session. The index opened at 4,123.83, a 0.32% increase, and continued to climb, reaching an intraday high of 4,168.17 (up 1.40%).
On the main board, individuals and foreign investors recorded net sales of 906.9 billion won and 118.8 billion won, respectively. In contrast, institutions made net purchases exceeding 1 trillion won, helping to support the index.
One of the factors behind the KOSPI's rise was Broadcom's earnings announcement after the U.S. market closed the previous day. Broadcom reported fourth-quarter sales of $18.02 billion and earnings per share (EPS) of $1.95, both beating Wall Street expectations. As a result, investment sentiment across the domestic AI Value Chain has rebounded. Kang Jinhyuk, a researcher at Shinhan Securities, analyzed, "Broadcom's explosive results have revived investment sentiment throughout the AI Value Chain, including semiconductors, nuclear power, and electrical equipment."
Among large-cap stocks, Samsung Electronics was trading at 1,085,000 won, up 1.12%. SK hynix rose 1.06% to 5,771,000 won amid expectations for improvements in the investment warning system. Hanwha Aerospace also showed strong gains of over 6%, trading at 9,590,000 won.
At the same time, the Korea Securities Dealers Automated Quotations (KOSDAQ) was trading at 934.18, down 0.46%. The KOSDAQ started slightly lower than the previous session and has been fluctuating within a narrow range.
