TL;DRKorea’s market now sets global AI sentiment. The Kospi-Nasdaq correlation has nearly tripled. SK Hynix’s US listing extended Korea’s influence into 24-hour trading.
Fund managers in London, New York, and Tokyo have added a new step to their morning routine: checking South Korean stocks. Korea’s $4 trillion equity market is now offering an early read on global AI risk appetite, as swings in SK Hynix and Samsung ripple through chip stocks worldwide. “We are all Korean investors now,” said Hani Redha, a London-based portfolio manager at PineBridge Investments. JPMorgan Asset Management’s chief Asia market strategist presented on Korea to the firm’s global team for the first time in his 14 years on the job.
The data confirms it. The 60-day correlation between the Kospi and the Nasdaq 100 has climbed to 0.46, near the highest in two years and almost triple its five-year average of 0.16. The linkage is even stronger during selloffs: the Nasdaq 100’s sensitivity to the Kospi during periods of Korean market weakness hit the highest level since 1990 on July 7. SK Hynix joined the trillion-dollar club earlier this year, and its US-listed shares now extend Korea’s influence into Wall Street trading hours. Redha tracks Seoul, then SK Hynix’s ADRs, then Korea-focused ETFs in New York. “It’s like almost 24-hour tracking,” he said.
