South Korea's Kospi crashes 5% again, plunges 31% in one month. Is the AI frenzy over?

South Korea's Kospi index plunged 31 percent from its June peak of 9,386 to 6,448.86, entering bear market territory after a nearly 14 percent crash in just two days. The selloff was driven by collapsing chip giants Samsung Electronics and SK Hynix, which together account for nearly half the index weight, compounded by rising oil prices amid Middle East tensions. South Korea's finance ministry warned that increasing concentration in the semiconductor sector is amplifying market volatility, while noting foreign investor profit-taking pressure is expected to ease in the second half.
