A whipsaw week of crashes and surges every other day amid AI-chip deleveraging. KOSPI settled the US semiconductor bear-market entry with a -4.46% (6,516.27) gap-down on Monday, then rebounded +3.56% (6,747.95) on Tuesday on customs semiconductor exports of $22.1 billion (+180.6%). After +0.74% on Wednesday it jumped +4.40% (7,096.89) on Thursday to reclaim 7,000, reading Alphabet's Cloud +82% as bullish. But the same print's capex guidance raise to $195-205 billion and buyback halt hit New York on 7/23, and on Friday KOSPI plunged -5.72% (6,690.62), handing back the entire rebound. The week lost about -1.9% yet swung 6,516-7,096, a 9% range. The demand strength of those who sell the pickaxe (memory) and the capex burden of those who pay for it (the hyperscalers) took turns winning the upside and the downside within a single week.
