On May 27, 2025, the Korean market experienced extreme divergence: KOSPI gained 2.25% to a record close above 8,200, but only 73 stocks advanced while over 820 declined, and KOSDAQ fell 3%. Guests Lee Kwon-hee and Jang Woo-jin analyzed the semiconductor-driven rally fueled by Micron's surge and the launch of 2x single-stock ETFs for Samsung Electronics and SK Hynix. They advised holding semiconductor leaders, buying dips in power equipment and secondary batteries, and warned against chasing thematic rotations as market liquidity contracts.
