Major U.S. stock indices turned south as markets digested fresh doubts surrounding the AI narrative. The S&P 500 and Nasdaq both slipped to their lowest levels in three weeks, with tech shares bearing the brunt of selling pressure. Investors are reassessing whether AI investments will truly deliver the promised returns—or if we've gotten ahead of ourselves. The selloff underscores a broader pattern: when Wall Street's confidence in hot sectors wavers, ripple effects often spread across asset classes, including crypto. Market cycles matter, and this pullback is a reminder that even the most hyped themes face cycles of doubt and reassessment.
