The Biggest Company In The S&P 500 Becomes The Third-Biggest In Wake Up Call
If you looked just at the week-over-week change in the S&P 500 (Index: SPX), you might think that not much newsworthy happened to influence stock prices during the final trading week of January 2025. The index fell just one percent from its previous week's close, ending at 6,040.53 on Friday, 31 January 2025.
But the same is not true for Nvidia (Nasdaq: NVDA which lost 17.0% of its total market capitalization on Monday, 27 January 2025 after news that China's DeepSeek artificial intelligence application was up and running became public over the weekend. That news shook AI stocks like Nvidia because the new AI system was reported to not require the company's high-end computer chips to be a viable competitor to established AI systems.
As that happened, NVDA stock went from accounting for 6.96% of the S&P 500's total market capitalization to 5.94%. That's the difference between being the biggest publicly-traded company in the index to the third-biggest.
According to S&P's Howard Silverblatt, Nvidia's stock had a 171% gain in 2024, contributing a little over one-fifth to the S&P 500's overall return of 25% for the year by itself. 2025 is shaping up to be a very different year for the AI stocks that powered the index in 2024.
Regardless, the latest update of the alternative futures chart finds the S&P 500's trajectory remained consistent with investors continuing to focus on the distant future quarter of 2025-Q4 through the past week, where the likely timing of a second rate cut by the Fed during 2025 is drawing their forward-looking attention.
Here are the daily highlights of the market moving headlines investors absorbed during the trading week.

The Atlanta Fed's GDPNow tool's final projection of real GDP growth rate for the now-past quarter of 2024-Q4 was a +3.0% annualized growth estimate, which overshot the BEA's official first estimate of GDP in 2024-Q4 of 2.3% annualized growth.
