AI Stock Leaders Stumble in October as Smart Money Shifts to Defensive Sectors

October marked a sharp reversal for U.S. stocks, as the high-flying artificial-intelligence trade hit turbulence. Worries over dwindling free cash flow and rising borrowing costs have prompted investors to reassess the mega-cap tech names that led the market earlier this year. The shift has been notable: many AI front-runners saw significant pullbacks, while sectors like utilities, healthcare, and consumer staples attracted fresh capital. This rotation reflects growing caution about the sustainability of AI-driven earnings and the impact of higher interest rates on growth stocks. According to market data, the S&P 500 fell roughly 2% in October, with the tech-heavy Nasdaq down over 3%, underscoring the breadth of the sell-off. Fund managers are now favoring companies with strong balance sheets and reliable dividends, a classic defensive posture. The move suggests that while AI remains a long-term theme, near-term risks are prompting a more selective approach. As the Federal Reserve signals rates may stay higher for longer, investors are bracing for continued volatility. The key question is whether this rotation is a temporary blip or the start of a broader market regime change.
