[Correlation Between U.S. Tech Stocks and South Korean Stock Market Rises to Highest Level Since 2021] Odaily Planet Daily News: According to data provided by asset management company Rayliant, the 60-day correlation between South Korea's KOSPI Composite Index and the Nasdaq 100 Index has recently climbed to around 0.50, reaching its highest level since 2021. Market participants warn that this closer relationship also brings risks, as the rising correlation erodes the diversification and risk-hedging effects traditionally sought by investors through holding both U.S. and South Korean stocks.
