Overnight US semiconductor and AI‑name valuation collapses spilled into Asian markets, triggering a second wave of heavy selling across Japan and the broader Asian tech supply chain in early July 17 trade. The Philadelphia Semiconductor Index fell 4.3% on July 16, marking a second day of weakness; TSMC reported Q2 net profit +77.4% YoY and raised full‑year capex guidance to $60–64bn from $52–56bn, yet its ADR fell 2.3% as markets question whether expanded AI compute investment will convert to timely cash flow and profit. Bloomberg macro strategists say the sharp US decline forced liquidations and long squeezes in leveraged equity funds, prompting large quant‑driven outflows from beta‑sensitive Japanese tech names including Kioxia, Tokyo Electron, Advantest and SoftBank in the Asian session. Geopolitical tensions and commodity‑driven valuation pressure, combined with renewed concern about higher forward inflation and prolonged high rates, add further downside risk for high‑markup growth tech stocks.
