Global Market Divergence Intensifies: Tech Giants' AI Spending Sparks Worries, Energy and Precious Metals Under Pressure

Keywords: US stock divergence, artificial intelligence, tech giants, international oil prices, consumer confidence

Introduction

On July 28, 2026, global financial markets showed significant divergence. The three major US stock indexes were mixed, with the Dow and S&P 500 rising, while the Nasdaq fell for the fifth consecutive trading day. Meanwhile, international oil prices dropped sharply, and all three major European indexes rose, creating a complex market sentiment. With the Fed about to announce its July rate decision, investors' concerns over tech giants' excessive AI spending, declining consumer confidence, and weak energy demand have become key factors driving market direction.

1. US Stock Divergence: Dow Strong, Nasdaq Under Pressure

As of the close on July 28, the Dow Jones Industrial Average rose 537.24 points to 52,747.32, up 1.03%; the S&P 500 edged up 15.6 points to 7,428.78, up 0.21%; and the Nasdaq fell 55.17 points to 24,876.91, down 0.22%. This trend extends recent market style rotation—capital shifting from overvalued tech stocks to cyclical and value sectors.


Large tech stocks showed mixed performance: Google rose over 2%, Microsoft gained over 1%, Apple hit an intraday high of $342.89 per share, briefly surpassing $5 trillion in market cap, becoming the second global company to reach that milestone after Nvidia. However, Tesla, Amazon, and Facebook fell slightly. The chip sector was weak, with the Philadelphia Semiconductor Index down 4.49%, Micron Technology and AMD both falling over 8%.

2. AI Investment Boom Sparks Market Concerns

Reuters reported that global market volatility intensified in July, with investors concerned about tech giants like Google, Microsoft, and Amazon excessively investing in AI data centers while competing for dominance in emerging technologies. Although AI is seen as the most promising growth area over the next decade, massive capital expenditures combined with unclear profitability paths are triggering a reassessment of return risks. High tech valuations and expectations of the Fed maintaining high interest rates create dual pressure, dragging the Nasdaq lower.

3. Consumer Confidence Declines, Fed Policy in Focus

The Conference Board survey showed the US Consumer Confidence Index fell to 90.8 in July from 92.2 in June. Consumers' inflation expectations for the next 12 months eased, but the proportion expecting higher interest rates in the year ahead remained unchanged at 61.3%. The Fed will release its July rate decision on Wednesday local time. According to the CME FedWatch Tool, traders priced in a 71% probability of rates unchanged and 29% probability of a 25-basis-point hike. Markets widely expect the Fed to maintain a cautious stance until inflation cools significantly.

4. Oil Falls for Third Day, Gold and Silver Decline

International oil prices fell sharply on July 28. Light crude for September delivery on NYMEX dropped $3.35 to $79.26 per barrel, down 4.06%; Brent crude fell $4.27 to $84.09 per barrel, down 4.83%. NYMEX crude has now fallen for three consecutive days, accumulating a 14.03% loss, while Brent crude lost 16.49%. Growing concerns over global economic slowdown weakening demand, coupled with a falling dollar index failing to lift oil prices, indicate bearish dominance.

In precious metals, COMEX gold futures fell 1.18% to $4,028.80 per ounce, and COMEX silver futures fell 2.35% to $57.34 per ounce. In a high-interest-rate environment, non-yielding assets face pressure.

5. Other Market Updates

European indexes all rose on July 28: UK FTSE 100 up 0.83%, France CAC 40 up 0.63%, Germany DAX up 0.41%. Chinese stocks listed in the US mostly rose, with the Nasdaq Golden Dragon China Index up 1.08%, led by Li Auto, NetEase, and JD.com. Energy stocks fell across the board, airline stocks collectively rose, and bank stocks were mixed.

Conclusion

Global financial markets are currently at a critical juncture with multiple intertwined factors: controversy over tech AI spending, weakening consumer confidence, divergence in Fed policy expectations, and weak energy demand create a complex and volatile trading environment. The Nasdaq's five-day losing streak and the Dow's strength reflect capital rotation from growth to value stocks. Going forward, markets will closely watch the Fed's interest rate decision signals and tech giants' earnings guidance on AI investment returns to judge whether the style rotation can persist. Investors should seize structural opportunities amid uncertainty and manage risks prudently.
