[Citigroup: U.S. Tech Stocks Face Risks Due to Overly Bullish Sentiment] Odaily Planet Daily News – According to Citigroup strategists, overly bullish positioning in U.S. tech stocks is exposing investors to the risk of a market reversal. The Citigroup team, including David Chave, stated that the ongoing enthusiasm for the artificial intelligence theme has pushed bullish market bets to the limit, making the Nasdaq 100 Index particularly vulnerable to shocks. 'Concentrated long positions in this index increase the likelihood of profit-taking and long-term unwinding in response to any negative factors, heightening the risk of a market downturn.' Since bottoming out in late March, the S&P 500 Index has risen 20%, while the Nasdaq 100 Index has soared 33%. According to momentum indicators, the Nasdaq 100 Index has been in an overbought state for nearly six weeks. (Jin10)
