The stock market saw significant fluctuations midday, with several high-profile companies making headlines due to unexpected developments across industries. Below is a detailed analysis of the biggest movers, the factors influencing their performance, and the broader market implications.
Nvidia Faces its Worst Day Since 2020
Nvidia, a leader in the chipmaking industry, experienced a dramatic drop of nearly 16% as concerns emerged regarding artificial intelligence investments. The catalyst? A language model from Chinese AI startup DeepSeek, whose performance raised skepticism about the scale and sustainability of AI-related investments. This marks Nvidia’s steepest single-day decline since March 2020, highlighting the volatility of the AI sector.

Chipmakers in Decline
Nvidia’s woes had a ripple effect on the semiconductor industry:
- Broadcom fell sharply by 17%.
- Micron Technology dropped approximately 11%.
- Advanced Micro Devices (AMD) slid by nearly 6%.
The VanEck Semiconductor ETF (SMH), a benchmark for the industry, plunged more than 9%. These declines reflect broader concerns about the semiconductor market’s heavy reliance on AI-related growth.

Tech Titans Under Pressure: Microsoft and Oracle
Tech giants Microsoft and Oracle also saw significant losses, falling over 3% and 11%, respectively. The primary concern stems from their multi-billion-dollar investments in AI infrastructure.
- Microsoft announced plans to allocate $80 billion for data center construction in fiscal 2025, with half of this investment targeting U.S. projects.
- Oracle, a key backer of the AI initiative “Stargate,” announced by former President Donald Trump, also faced skepticism over its future returns.
These losses underscore the uncertainty surrounding the profitability of large-scale AI projects.
Power Stocks Crumble Amid AI Data Center Concerns
Power companies involved in AI data center development were hit hard:
- Constellation Energy and Vistra tumbled by over 18% and 27%, respectively.
- GE Vernova and Talen Energy recorded even steeper declines, plunging 20% and 22%.
This sector’s struggles highlight the challenges of aligning energy infrastructure with AI’s rapid growth.

Crypto Stocks Follow Suit
The tech stock rout extended to the cryptocurrency sector:
- Coinbase and MicroStrategy fell by 7% and 5%, respectively.
- Bitcoin mining stocks tied to AI ventures faced even deeper losses, with Core Scientific dropping 28%, TeraWulf losing 27%, and Iren (formerly Iris Energy) down 23%.
The crypto market remains closely tied to the tech industry’s movements, underscoring its volatility.

AT&T Surges on Strong Earnings
Amid the broader selloff, AT&T provided a rare bright spot, rising nearly 6%. The telecom giant reported:
- Fourth-quarter adjusted earnings of 54 cents per share, surpassing analyst expectations of 50 cents.
- Revenue of $32.3 billion, beating the consensus estimate of $32.02 billion.
This performance highlights AT&T’s resilience in an otherwise turbulent market.

Sector-Specific Movers
SoFi Technologies
Shares of SoFi slid 10%, overshadowed by a weak first-quarter outlook despite reporting better-than-expected earnings and revenue results.
Travel + Leisure
Bank of America upgraded Travel + Leisure to “buy” from “underperform,” citing double-digit earnings growth potential amid robust demand for leisure travel. The stock rose by 2% in response.
Titan Machinery
The equipment retailer surged 10% after Baird upgraded it to “outperform,” citing shrinking inventories as a positive catalyst for future performance.
Exelixis
Biotechnology firm Exelixis gained 2% after Morgan Stanley upgraded the stock, describing its valuation as “undemanding.”
Ralph Lauren
Luxury apparel brand Ralph Lauren fell 3% following a downgrade from Raymond James, which cited limited upside potential due to the strengthening U.S. dollar and the stock’s recent rally.
Market Takeaways
