The S&P 500's current winning streak is hanging by a thread as a broad sell-off in artificial-intelligence stocks grips technology markets. The sell-off, which has gathered pace over recent sessions, is feeding volatility across global equity markets and prompting money managers to rethink their portfolios. Rising bond yields are compounding the pressure, raising questions about how long the index's run can last.
AI Sell-Off Accelerates
Investors have been dumping shares of companies tied to artificial intelligence, a sector that had powered much of the market's recent gains. The selling is concentrated but has spilled into the broader tech space, dragging down the S&P 500's technology sector. While the exact trigger varies by day, the shift appears tied to growing unease that AI valuations had outpaced reality—and that higher yields could further undermine the sector's appeal. The result is a market that no longer rewards the AI narrative as generously as it did just weeks ago.
Volatility Spills Over
The turbulence isn't staying inside U.S. borders. Global equity benchmarks have wobbled as the AI rout compounds existing uncertainties around interest rates and economic growth. In Europe and Asia, indexes tracking technology stocks have mirrored the S&P 500's swings, suggesting the sell-off is part of a broader repricing rather than a localized event. For traders, the message is clear: the AI trade that once seemed unstoppable now carries real downside risk.
Investors Adjust Strategies
Portfolio managers are responding by shifting money out of high-growth tech names and into defensive sectors such as utilities and health care. Some are trimming overall equity exposure or adding hedges to protect against further drops. The adjustments come as the S&P 500's streak—measured in consecutive trading days without a significant decline—faces its toughest test in months. The duration of the current winning streak is not specified, but analysts following the index note that each new session without a pullback raises the stakes.
Rising Yields Add Pressure
Bond yields have climbed in recent days, driven by expectations that central banks may keep interest rates higher for longer. Higher yields make future cash flows from tech and AI companies less attractive, a dynamic that amplifies the sell-off. The combination of rising rates and falling AI stocks creates a feedback loop: as yields push higher, tech stocks fall; as tech stocks fall, yields climb further because investors demand more compensation for risk. That loop now threatens to break the S&P 500's streak unless a catalyst emerges to reverse the momentum.
Whether the index can hold its run depends largely on whether AI stocks stabilize in the coming sessions. No big earnings reports or policy decisions are scheduled this week, so market direction will likely be set by the next wave of selling—or the absence of it. The streak's fate may be decided by Friday's close.
