Wall Street Stabilizes Amid AI Stock Volatility
Wall Street found stability on Thursday, October 15, 2026, after a turbulent session marked by significant declines in artificial intelligence-related stocks. Investor concerns about the longevity of the AI boom, coupled with inflation pressures, drove the market volatility.
The S&P 500 managed to erase early losses, closing up by 0.1%, while the Dow Jones Industrial Average surged 482 points. In contrast, the Nasdaq Composite fell by 0.4%, primarily due to continued weakness in AI stocks. Notable declines included Nvidia, which dropped about 2%, and CoreWeave, which fell 3.5% after an earlier 15.5% slump.
Treasury yields provided some relief, retreating during the session. The 10-year yield dipped to approximately 5.09%, down from about 5.19% earlier, easing some of the pressure on borrowing costs.
The previous day, October 14, had seen U.S. markets experience their worst day since July, with the S&P 500 falling around 1.11% and the Nasdaq dropping about 1.88%. This was largely due to hot inflation data that heightened expectations for further Federal Reserve rate hikes, adversely affecting AI-linked stocks.
Market analysts noted a sector rotation, with investors moving away from AI-heavy technology stocks in favor of more defensive sectors. This shift contributed to the Dow's outperformance relative to the Nasdaq.
