■ Supply and Demand Trends: Institutions Lead, Foreigners Take Profits In the securities market, institutions strongly drove the index higher with net purchases of 1.4181 trillion won. Individual investors also joined in with net purchases of 54 billion won. On the other hand, foreigners sold a net 1.4853 trillion won, appearing to lock in profits. In the KOSDAQ market, individuals made net purchases of 231.1 billion won, but foreigners and institutions sold a net 155.3 billion won and 75.2 billion won, respectively. In the futures market, institutions recorded net sales of 673 billion won, while foreigners and individuals made net purchases of 315.7 billion won and 267.6 billion won, respectively.

■ Sector Performance and Future Outlook By sector, strong buying inflows centered on large-cap stocks such as semiconductors, power equipment, shipbuilding, and defense led the KOSPI's rally. The market analyzed that the strong earnings report from U.S. semiconductor company Micron and growing expectations for expanded AI memory demand significantly improved investment sentiment in the domestic semiconductor sector. Meanwhile, the KOSDAQ was unable to avoid weakness as profit-taking sell-offs emerged, centered on some biotech and small-to-mid-cap growth stocks. Given that foreign profit-taking selling pressure continues, changes in supply and demand and the trajectory of the U.S. stock market are expected to serve as key variables in determining the further direction of the domestic stock market.
