Citi Advises Staying Invested in AI Despite Bubble Concerns, as Riding Manias Can Be Profitable
Citigroup's Stance on AI Stocks: Citigroup's Dirk Willer believes that the recent fluctuations in AI stocks do not indicate the end of a bubble, suggesting that investors should remain invested as bubbles can still be profitable initially.
Focus on Corporate Profits: Willer emphasizes that the bank's equity strategist is prioritizing corporate profits over concerns about a potential bubble burst, using liquidity and technical analysis for better market predictions.
Market Performance and Predictions: Despite a 1.5% dip in the Nasdaq Composite in November, it is projected to end 2025 over 22% higher, remaining close to its all-time high.
Monetary Policy Impact: Willer notes that an anticipated reduction in interest rates by the Federal Reserve could support stock performance, although historical trends suggest that mid-term election years may pose challenges for equities.
