한국·대만증시, AI 덕에 급부상했지만 '쏠림 심화'는 리스크

South Korea and Taiwan stock markets have surged to 8th and 6th place globally, driven by AI-related semiconductor demand, marking a significant shift in the global market hierarchy. However, this growth is heavily concentrated in a few companies (Samsung Electronics and SK Hynix for Korea; TSMC for Taiwan), creating structural concentration risk that limits future upside and increases volatility. This over-reliance on mega-cap stocks mirrors similar vulnerabilities in other markets like Saudi Arabia and Denmark, signaling that concentrated market structures could face sharp corrections when investor sentiment shifts.
