Wall Street Tech Stocks Fall on AI Spending Worries
Wall Street saw major tech stocks fall on Thursday, with the S&P 500 and Nasdaq hitting multi-month lows. Investors worried about AI spending plans from Alphabet and a weak forecast from Qualcomm. Alphabet shares dropped over 3%, and Qualcomm slid 8.2%. Other big tech companies like Microsoft and Tesla also saw declines. This sell-off wiped out about $830 billion from the S&P 500 software and services index since January 28.
AI Spending Fears Drag Down Wall Street Stocks
Wall Street stocks fell on Thursday, with the Nasdaq reaching its lowest point since November. Alphabet's shares dropped 4.2% after its AI spending plans worried investors. Many are concerned about the large investments in AI without clear signs of increased revenue and profits. This also raised fears that new AI tools could reduce demand for traditional software. The S&P 500, Nasdaq, and Dow Jones all saw declines, and most S&P 500 sectors were down.
AMD Stock Falls on AI Revenue Outlook Concerns
Advanced Micro Devices AMD stock dropped 17.31% to $200.19 on February 4. This fall happened because the company's sales forecast for the first quarter of 2026 was lower than investors hoped. Even though AMD had strong results for the fourth quarter of 2025, concerns grew about its AI data center growth compared to Nvidia. CEO Lisa Su mentioned that AI chip revenue from China will be limited for now and operating costs are increasing. Investors are looking for clearer signs that AI growth will lead to steady profits for AMD.
Global Markets React to AI Stock Sell Off
Global markets saw shifts on February 4 and 5, 2026. Wall Street experienced an AI stock sell-off, causing the Nasdaq to drop 1.5% and the S&P 500 to fall 0.5%. Silver hit a new low, down 38% from its January 29 peak, and Bitcoin fell 3% to $US70,477. The Australian share market also closed down 0.5%, with materials stocks falling due to AMD's 17.3% plunge and lower uranium futures. Meanwhile, Bendigo Bank announced a 0.25% interest rate increase for savings accounts starting February 16, 2026.
Nvidia Rises as Foxconn Sees Strong AI Rack Demand
Nvidia's stock rebounded after Foxconn, also known as Hon Hai, reported huge sales growth in January. Foxconn stated that shipments of AI racks continue to increase. The electronics maker expects its performance for the current quarter to be better than the average of the past five years. This news suggests strong ongoing demand for AI infrastructure.
AI Revolution Creates Winners and Losers in Tech
The AI revolution is changing how investors approach tech stocks. The idea that AI lifts all companies is over, and investors must now carefully choose winners. A "software-mageddon" recently removed about $800 billion from the S&P 500 software and services index. This shift is partly due to new AI tools, like Anthropic's legal plug-in, which can automate many tasks. Experts believe the tech world is dividing into companies that disrupt with AI and those that become casualties. This means active stock picking may become more important than passive investing.
Markets Drop as AI and Economic Fears Grow
Financial markets fell on February 5 due to worries about AI spending and a weakening economy. The S&P 500, Dow Jones, and Nasdaq Composite all saw declines. Alphabet's stock dropped over 3% after it announced plans to spend $185 billion on new technology. Economic reports showed a weaker job market, with job cuts at their highest since 2009. Bitcoin plunged 8.5% to $67,389, its lowest since 2024, and Ethereum also fell.
Super Micro Computer Stock Surges Amid AI Boom
Super Micro Computer SMCI stock has surged over 150% this year, even outperforming Nvidia. The company's strong second-quarter results show a 49% increase in revenue year-over-year, beating analyst predictions. This growth comes from the high demand for AI infrastructure, especially SMCI's powerful servers needed for AI models. However, investors should be careful due to SMCI's high price-to-earnings ratio, possible profit margin pressure, and significant debt. Despite these risks, SMCI remains an appealing option for those wanting to invest in the AI market.
