Korean Stock Market Weekly Recap (July 12–18, 2025): KOSPI's gains capped despite foreign dip-buying, KOSDAQ extends rally for 3rd week on strong retail buying. Foreigners bought electronics, autos, and pharma; institutions rotated into auto parts, metals, pharma, and financials. Key issues: Trump tariff remarks, US CPI, Korean gov't high-tech investment plans, and rising KRW/USD rate.

1. Market Recap

KOSPI rose +10.65p (+0.34%) to close at 3,188.07 (July 19). Foreign buying in large-cap semis briefly pushed the index above 3,200, but global uncertainty and institutional profit-taking capped gains late in the week.
