As expectations of the KOSPI breaking the 9,000-point level and growing risk appetite expanded, buying interest spread across diverse sectors including semiconductors, electric wires, biotech, secondary batteries, and securities.

With buying interest spreading across industries and the number of rising stocks increasing significantly, market observers noted that stocks with short-term sharp gains may experience expanded volatility, advising investors to closely monitor trading volume, supply and demand dynamics, and corporate disclosures.
