AI Rally Frothy but Not a Bubble, Goldman Sachs Warns
Goldman Sachs says the AI-fueled rally has left U.S. stocks exuberant but not bubble-level yet: a cluster of market-behavior indicators sits around the 86th percentile (below dot-com era and 2021 peaks), while improving earnings expectations and a 2026 S&P 500 earnings forecast of $340 per share support valuations. Sentiment is mixed—bearish bets tick up and Goldman’s gauge remains subdued—so the setup is frothy but not a full-blown bubble.
