On the 31st, Samsung Electronics (005930) closed with a sharp rally in the regular session. According to KRX data that afternoon, Samsung Electronics finished trading at 262,500 won, up 26.81% from the previous day. During the session, it recorded an intraday high of 267,000 won, demonstrating robust buying interest. Bolstered by improved investor sentiment following a surge in U.S. semiconductor stocks, the company expanded its gains from early in the session and maintained its strength into the afternoon, drawing keen attention from investors. In particular, SK Hynix hit the upper limit during the session that same afternoon, reflecting a trend of concentrated buying centered on large-cap semiconductor stocks. As the nation's two semiconductor leaders rallied together, overall market investor sentiment improved further. The upward momentum is an extension of a global semiconductor tailwind. Overnight in the New York stock market, the Philadelphia Semiconductor Index rose sharply, and major semiconductor stocks such as Micron, AMD, and Intel surged all at once, heightening expectations for an improvement in the AI semiconductor cycle. This positive trend appears to have carried over directly into the domestic stock market, drawing strong buying interest centered on Samsung Electronics and SK Hynix. That day, both the KOSPI and KOSDAQ indices also recorded double-digit gains, reflecting a spreading preference for risk assets. Buying interest spread broadly across large-cap growth and policy-benefit stocks, led by semiconductors as well as AI, power equipment, and nuclear power. The market is closely watching whether the semiconductor sector, with Samsung Electronics and SK Hynix showing strength in tandem, will serve as the key driver of the domestic stock market rally.
