In Seoul on Tuesday, the KOSPI index surrendered more than four percent of its recent record-setting gains, as the semiconductor giants Samsung and SK Hynix — the very engines of the rally — reversed sharply and pulled the broader market with them. The retreat was part of a wider cooling across Asian tech stocks, where an AI-driven surge had lifted valuations to heights that, in hindsight, may have outpaced the underlying reality. Markets built on a single narrative are always one mood-shift away from reconsideration, and this week, that shift arrived.
