"Big Bull" Ed Yardeni: Don't Chase AI Stocks Now, There's AI Fatigue

Wall Street's most optimistic bull has rarely slammed the brakes on AI. Yardeni warns the market is showing "AI fatigue" and advises shifting away from individual tech stocks toward QQQ and AI application sectors like financials and healthcare. However, he remains confident that this earnings-driven bull market has no bubble, with the S&P 500 targeting 8,400 points, and the "Roaring 2020s" continues.
