[Citigroup Downgrades South Korea Stock Market Rating to 'Neutral'] BlockBeats News, July 20, Citigroup has downgraded South Korea's stock market rating from 'Overweight' to 'Neutral' due to the sharp volatility in chip stocks in recent weeks. The bank is seeking to reduce its investment exposure to the artificial intelligence theme. As a prime example of the frenzy surrounding AI trading, South Korea's KOSPI index has become the best-performing stock market globally this year. However, in recent weeks, the market has experienced significant fluctuations due to retail investors' enthusiasm for leveraged single-stock ETFs and valuation concerns. Citigroup remains structurally bullish on the prospects of the artificial intelligence sector but has adjusted its stance on the South Korean market to neutral.
