S&P 500 Drops as AI Balloon Starts to Pop

The S&P 500 (Index: SPX) dropped 3.1% week over week, closing at 5,770.20 on Friday, 7 March 2025.

Much of the week's headlines tried to connect U.S. tariffs to the market downswing, but that misses a bigger story that's developing. The Artificial Intelligence balloon may be beginning to pop.

You have look at the week's second-tier market-moving headlines to get that part of the story. Many of the biggest drops were among the stocks of companies that had been riding high on the AI wave. And for what it's worth, AI-leader Nvidia (NASDAQ: NVDA) dropped well below the $3 trillion capitalization mark during the past week. Since the beginning of the year, NVDA has lost $1 trillion of its market capitalization.

Despite that loss, NVDA is still the third-largest company within the S&P 500. As such, what's going on with it and other AI-related stocks is enough to pull the S&P 500 lower. The latest update of the alternative futures chart shows the trajectory of the S&P 500 is running below the projected trajectory associated with investors focusing their attention on the upcoming future quarter of 2025-Q2.

That situation suggests the negative change in fortune for the AI sector of the stock market may be prompting a change in market regime. It's still too early to make that determination for sure, but it's a potential to which we're paying close attention behind the scenes.

Here are the week's market moving headlines:

Monday, 3 March 2025
Tuesday, 4 March 2025
Wednesday, 5 March 2025
Thursday, 6 March 2025
Friday, 7 March 2025

The CME Group's FedWatch Tool projects the Fed will resume cutting rates with a quarter point rate reduction when Fed meets on 18 June (2025-Q2). The FedWatch tool now anticipates rate cuts at 6-12-week intervals in the second half of 2025, with quarter point rate cuts forecast for 30 July (2025-Q3), and 29 October (2025-Q4).

The Atlanta Fed's GDPNow tool's projection of what real GDP growth will be in the 2025-Q1 declined from last week's -1.5% annualized growth rate to -2.4%. The GDPNow estimate is believed to be sending a false signal given very high imports of gold to the U.S. (originating from Canada, Switzerland, and surprisingly, Hong Kong), which have shown up as imports in trade data, but which have not yet been updated in inventory data tracked by the GDPNow tool. Forecasts of GDP in 2025-Q1 will be revised higher after accounting for the imported gold rush.
