Whoa, the return volatility of South Korea's KOSPI index has surged to 63% this year, not only ranking first among major global stock indices but even surpassing Bitcoin's 48% volatility during the same period. The reasons? AI and memory chips. Samsung Electronics and SK Hynix now account for over half of KOSPI's weight. The Korean stock market is increasingly resembling a high-leverage AI ETF driven by just two chip companies. At the same time, retail investors are piling into single-stock leveraged ETFs, while foreign capital flows amplify the market swings even further. On July 28, KOSPI plummeted 10.84% in a single day; Three days later, the index soared nearly 18% in one day. Samsung and SK Hynix jumped approximately 27% and 30%, respectively, on the same day. In the first half of 2026, the Korean exchange triggered 29,357 individual stock volatility interruptions—a record for the same period in history. Market-wide circuit breakers have been activated 8 times, compared to zero in 2025. Bitcoin is gradually being 'tamed' by ETFs and institutional money. Meanwhile, the Korean stock market, fueled by AI mania, index concentration, and retail leverage, has transformed into a new high-volatility asset. In the past, Koreans turned to crypto for thrills. Now, just holding Samsung and SK Hynix might already be enough. #AI #Crypto #KOSPI #Samsung #SKHynix
