The U.S. stock market experienced a notable pullback on Friday, December 12, 2025, particularly impacting technology stocks linked to artificial intelligence. By around 12:30 p.m. ET, the Nasdaq was down approximately 1.8%, and broader indices like the S&P 500 and Dow Jones also showed declines, as investors reacted to concerns over profit margins and capital expenditures in the tech sector. This shift in sentiment follows a recent period of robust market performance.
Investor mood shifted dramatically from Thursday’s positive momentum to a more cautious stance, especially in technology, amid rising bond yields and renewed skepticism regarding whether the AI boom can justify current valuations. The Nasdaq 100 proxy, QQQ, was down about 1.84% at approximately 12:27 p.m. ET, while the S&P 500 and Dow were off 1.08% and 0.40%, respectively. Small-cap stocks also faced pressure, with the Russell 2000 index, tracked by IWM, down more than 1%.
This selling pressure was largely driven by significant declines in several key tech stocks. Broadcom, for example, saw its shares tumble 10.53% to around $363.60 after the company warned that a higher mix of lower-margin AI-related products could negatively impact profitability. This development has raised alarms among investors who are already wary about the sustainability of AI-driven growth.
Oracle also contributed to the negative sentiment, with shares falling 5.02% amid concerns about a drastic increase in capital expenditures related to its AI investments. The company’s warning has sparked fresh discussions around the valuation of tech stocks, particularly those tied to AI, as investors weigh the potential for long-term profitability against immediate spending demands.
Among the hardest-hit stocks were Fermi, which plummeted 34.66% to approximately $9.97 following the termination of a crucial $150 million funding agreement. Other notable declines included SanDisk, down 12.78% to $210.74; Netskope, falling 11.34% to $20.84; and several AI-adjacent firms such as Corning and Arista Networks, which dropped by 7.17% and 6.62%, respectively. The broader trend reveals a market increasingly skeptical about the short-term viability of many tech investments tied to AI.
This market behavior reflects a growing demand for clearer evidence that AI investments will yield sustainable profits rather than just revenue increases. Developments in companies like Broadcom and Oracle have heightened worries among investors about the actual return on investment in AI technologies. Analysts have noted that while Broadcom reported strong performance metrics, its margin concerns sent the stock into a downturn, highlighting how the market is now prioritizing earnings quality over growth potential.
Looking ahead, the market is poised to receive key economic data that could influence investor sentiment further. Strategists are focusing on upcoming reports related to employment and inflation, which could serve as catalysts for market movement. Despite the current selloff, many investors remain optimistic about the long-term prospects of AI technologies, although there is a growing recognition that valuations may need to adjust based on the timing of profitability.
The question remains not just whether AI investments will generate revenue, but when they will translate into improved margins. As the market reassesses its approach to tech stocks, particularly those linked to AI, the ongoing discussions about capital expenditures and profitability will likely dominate conversations among analysts and investors alike. Observers will be closely monitoring how these dynamics evolve in the coming weeks.
