By late July 2026, Kospi-Nasdaq correlation hit a five-year high of 0.5 due to market concentration in Samsung, SK Hynix, and top S&P 500 names. Recent events, including China's chip progress and ChangXin Memory's surge, triggered synchronized semiconductor selloffs. Tightening investment loops between chipmakers, developers, and cloud providers increase contagion risk, while heavy capex strains cash flows if adoption lags." datetime: "2026-08-20T07:54:11.000Z" locales: - [zh-CN](https://longbridge.com/zh-CN/news/296453304.md) - [en](https://longbridge.com/en/news/296453304.md) - [zh-HK](https://longbridge.com/zh-HK/news/296453304.md) generator: "portal-rs" --- # Prescient warns AI-driven chip rally erodes global equity diversification benefits - Prescient analysis flagged weakening global equity diversification as AI-linked stocks drive cross-border risk in chip-heavy markets. \* By late July 2026, the 60-day Kospi–Nasdaq 100 correlation rose to about 0.5, the highest since 2021. \* Concentration amplified moves: Samsung Electronics and SK Hynix exceeded half the Kospi; the top 10 S&P 500 names neared 37%. \* Late-July China chip-equipment progress, ChangXin Memory’s 466% debut triggered a synchronized selloff in semiconductors across Korea, Taiwan, the US. \* Investment loops between chipmakers, model developers, cloud providers tighten contagion risk; cash flow strain from capex raises downside if adoption lags.
