AI Spending Fears Pressure Nasdaq, with S&P 500 Downside in October

Why it may matterVerify against the original reporting
The headline implies a large, negative repricing in Nasdaq driven by AI spending fears, which often precedes broader risk-off moves. Historically, tech-led Nasdaq declines have spilled into the S&P 500 when AI or growth expectations falter, especially if mega-cap tech leaders underperform amid weaker capex signals (e.g., AI hype cycles followed by slower-than-expected spending). A confirmed October drawdown would raise risk-off sentiment, impacting valuation multiples and earnings revisions across large-cap tech names that drive S&P 500 performance.
