The correlation between South Korean stocks and US tech stocks has reached a near two-year high, positioning the South Korean market as a key indicator for global AI investment sentiment. The 60-day correlation coefficient between the Korea Composite Stock Price Index (KOSPI) and the Nasdaq 100 Index has surged to 0.46, significantly above the five-year average of 0.16. This trend has led global fund managers to closely monitor South Korean tech giants like Samsung Electronics and SK Hynix for early signals of market movements. The heightened sensitivity of the Nasdaq to South Korean stock fluctuations is particularly notable during market downturns. On July 7, the correlation indicator reached its highest level since 1990, underscoring the growing influence of South Korean stocks on global tech investment strategies.
