Driven by the artificial intelligence boom, the share prices of South Korea's two major weighted stocks, SK Hynix and Samsung Electronics, have strengthened. The Korea Composite Stock Price Index (KOSPI) hit an all-time high on Monday, surging 4.3% to 7,822.24 points, with a cumulative increase of 85.6% this year. Analysts pointed out that with the increase in capital expenditures in the artificial intelligence sector, there is still room for growth in the South Korean stock market. JPMorgan raised its target for the Korea Composite Stock Price Index, expecting memory chip prices to continue to rise. However, Samsung Electronics is facing labor disputes, and rising labor costs may impact its operating profit. As of Monday, SK Hynix's market capitalization reached 1,300 trillion won, and Samsung Electronics' market capitalization reached 1,700 trillion won. This rally is primarily driven by retail investors, while foreign investors are opting to take profits, and institutional investors are showing net buying.
