The reason is that half of the Kospi is made up of just two stocks—SK Hynix and Samsung—both deeply tied to the AI boom. Retail investors, many using leveraged ETFs in what Bloomberg's Neil Callon describes as a "gamified" finance culture, got caught on the wrong side of a sudden shift in sentiment. The trigger was a fresh wave of fear that China is catching up in AI, threatening the entire economic logic underpinning the industry's massive spending spree.
