AI Stocks Decouple From Broader Market as Correlation Hits Record Low

The 40-day correlation between the US Broad AI Index and the S&P 500 excluding AI components has reached a record low of -0.60. This statistical divergence confirms that AI-linked equities are increasingly trading in the opposite direction of the general market.

This negative correlation trend has remained in place since late June. The current data marks a historic shift in market dynamics, as the performance of the AI sector becomes entirely decoupled from the remaining constituents of the S&P 500 index.
