According to CoinMeta, the South Korean KOSPI index closed up 18% on Friday, significantly reversing the downward trend of the previous three days and setting a record for the largest single-day increase ever. According to LSEG data, five of the top ten single-day increases in the KOSPI index have occurred since March, while three of the four largest single-day declines in the past decade have happened within the last five weeks. Peter S. Kim, global strategist at KB Financial Group, stated that the gamification of the stock market has led to intense volatility, which is more driven by news developments and trends rather than fundamental factors. William Braton, an analyst at BNP Paribas in France, said that South Korea is becoming the focus of discussions regarding the sustainability issues of the AI-driven technology supercycle.
