[Citi Downgrades South Korea Stock Market Rating to 'Neutral,' Upgrades China to 'Overweight'] According to Deep Tide TechFlow, on July 20, Citi downgraded South Korea's stock market rating from 'Overweight' to 'Tactical Neutral,' primarily due to significant recent volatility in chip stocks, prompting a reduction in its exposure to the AI theme. Citi noted that while South Korea's stock market has performed strongly this year, driven by AI-related trading, retail investors' pursuit of leveraged single-stock ETFs and valuation concerns have intensified market fluctuations. Meanwhile, Citi maintains a structurally bullish outlook on the AI theme and has upgraded China's market rating to 'Overweight.'
