Woofun AI data shows that the correlation coefficient between the KOSPI index and the Nasdaq 100 has risen to 0.46 over the past 60 days, approaching a two-year high and reaching three times the five-year average of 0.16. Fund managers in London, New York, and Tokyo increasingly monitor South Korea's $4 trillion market as a primary indicator of global AI risk appetite, with Japanese traders adding the KOSPI to daily watchlists.

The South Korean market plunged nearly 9% last week amid doubts over AI demand, causing SK Hynix ADRs to fall 9.3% and triggering spill-over effects on Wall Street. Since the June peak, the KOSPI has dropped 25%, wiping out approximately $1 trillion in market capitalization, while Samsung Electronics and SK Hynix shares declined by at least 30%. In response to amplified volatility from high-leverage trading, South Korea suspended new single-stock leverage products. Despite these losses, the KOSPI remains up 62% year-to-date, leading major global markets.
