Dramatic fluctuations in artificial intelligence stocks created chaos on Wall Street Tuesday, leading to mixed performance across major market indexes.
The S&P 500 dropped 0.3% after experiencing wild swings that saw the index jump 1% in early trading before plunging 2.3% by midday. Meanwhile, the Dow Jones Industrial Average managed a slight 0.2% increase, while the Nasdaq composite declined 1%.
Market volatility intensified when businesses involved in semiconductors, memory components, and other foundational AI technologies reversed course from morning gains to afternoon declines. The weakness in artificial intelligence stocks overshadowed benefits from falling crude oil prices, even though the majority of S&P 500 companies posted gains. Bond market activity showed Treasury yields declining slightly.
