Intraday Volatility Explodes... Semiconductor Concentration Starts Again, What Now? / Why Samsung Electronics Stock Price is Soaring

Summary

Park Geun-hyung, Department Head at IBK Investment & Securities, discusses the return of semiconductor-driven market concentration after a brief KOSDAQ rotation. He explains why the memory supercycle remains intact, pushing Samsung Electronics and SK Hynix higher, supported by supply shortages and Apple's failed attempt to secure cheaper Chinese memory. The conversation covers spillover into semiconductor equipment, materials, and power infrastructure, the distortion caused by leveraged single-stock ETFs, and why domestic consumption sectors like cosmetics fail to sustain gains despite strong tourist spending.

• The memory supercycle continues with supply tightness, forcing even Apple to accept high DRAM prices and making Chinese CXMT memory irrelevant due to low volume and similar pricing.
• Semiconductor equipment and materials stocks are rallying on large capex programs and semiconductor cluster investments, with rotation from front-end equipment to materials.
• Power cable, transformer, and renewable energy names like SK Eternix benefit from semiconductor cluster water and power demand.
• Single-stock leveraged ETFs on Samsung Electronics and SK Hynix have concentrated retail flows, artificially driving the KOSPI while leaving other sectors behind.
• KOSDAQ's brief 8% surge was a rotational rebound, but the market quickly shifted focus back to large-cap semiconductor names.
• Domestic consumption sectors such as cosmetics and beauty devices fail to sustain rallies despite record inbound tourist spending, reflecting the dominance of semiconductor concentration.
