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.

The negative economic data prompted a major change in the expectations of future rate cuts in 2025. The CME Group's FedWatch Tool still projects a quarter point rate cut when Fed meets on 18 June (2025-Q2), but the big change took place in the expectations for following months. The FedWatch tool now anticipates rate cuts at 12-week intervals through 2025, with quarter point rate cuts forecast for 17 September (2025-Q3) and 10 December (2025-Q4).

The Atlanta Fed's GDPNow tool's projection of what real GDP growth will be in the 2025-Q1 plunged from last week's +2.3% annualized growth rate to -1.5%. The change indicates the economy will shrink during 2025-Q1, driven by two negative contributions involving January 2025 economic data. The larger contribution is a decline in net exports, which dropped following Biden-Harris anti-free trade actions on semiconductors that went into effect at the beginning of the year. Meanwhile, a smaller contribution came from reduced personal consumption expenditures, although personal incomes and personal savings rose in January. This latter contribution may be tightly concentrated among federal government workers and contractors, including those at non-governmental organizations.
