The mega-cap tech stocks lost $2.3 trillion in value last month as investors questioned their massive AI spending. While Goldman Sachs argues this spending powers the bull market, falling oil prices and successful Iran negotiations are deflating the defense and energy premiums that usually support old-economy industrial stocks, creating a double-whammy for the broader index.

## Idea

This thesis synthesizes the $2.3 trillion mega-cap wipeout with the sudden drop in oil prices and Goldman's defense of capital spending. While Goldman claims AI spending is fueling a generational bull market, the market is voting with its feet and punishing that exact spending. Combine this with deflationary pressures from falling oil, and the near-term direction for the S&P 500 and Nasdaq looks lower.
