## Market divergence signals risk
The S&P 500 sits near record highs while the average stock struggles with narrowed leadership and deteriorating participation.
## 60% of stocks below 20% peak
Roughly 60 per cent of S&P 500 constituents are down more than 20 per cent from their individual highs.
## Historic market weakness
Market breadth has been this weak only twice before: during the 1973, 74 bear market and at the peak of the technology bubble in 1999, 2000.
## AI-driven market concentration
The market is being carried by a remarkably small group of companies tied to artificial intelligence.
## AI infrastructure costs
Financing the AI buildout could exceed US$10 trillion between 2025 and 2032 according to a recent Brookings Institution study.
## Capital strain from AI and debt
The same pool of capital required to finance AI infrastructure must also absorb massive U.S. Treasury issuance as Washington runs large fiscal deficits.
## Key takeaway

The S&P 500 nears record highs while 60% of stocks fall more than 20% from their peaks, signaling a market increasingly driven by AI companies that require massive capital investment.
