# Chip Stocks Plunge, Philadelphia Semiconductor Index Tumbles 4.7%; Nvidia Slides Over 5%

US equity markets diverged in midday trading on July 27. As of writing, the S&P 500 slipped **0.3%**, the Nasdaq Composite fell **0.6%**, while the Dow Jones Industrial Average edged up **0.2%**. The Philadelphia Semiconductor Index plunged **4.69%**, weighing heavily on the broader market. International crude oil prices tumbled over **6%**, dragging energy stocks lower in tandem.

Semiconductor names suffered a broad-based selloff after Nvidia unveiled over **$750 billion** in AI investment commitments, raising concerns over its balance sheet. In contrast, software-oriented tech stocks bucked the trend, with Microsoft and Oracle among the top gainers.

**Chip Sector Rout Deepens; Nvidia Slides Over 5%**

As of writing, Nvidia (NVDA) dropped **5.02%** to **$196.46** on volume exceeding **100 million shares**. SK Hynix (SKHY) tumbled **7.85%** to **$142.44**; Super Micro Computer (SMCI) fell **4.05%**; Intel (INTC) declined **2.50%**. The selloff was triggered by Nvidia's weekend announcement of over **$750 billion** in AI investment pledges, including partnerships with SK Group and a **$250 billion** financing guarantee for OpenAI. Jim Cramer cautioned that the financing strategy echoes the excesses seen during the dot-com bubble era, stoking market fears over balance-sheet risk.

**Software Tech Stocks Rally; Microsoft Jumps Over 3%**

As of writing, Microsoft (MSFT) rose **3.09%**, with investors optimistic ahead of its upcoming quarterly earnings report, where strong cloud revenue and AI-driven growth are widely anticipated. Oracle (ORCL) gained **4.23%** to **$119.86**; UiPath (PATH) surged **6.94%**. Wall Street has increasingly shifted its focus from traditional revenue metrics to AI capital expenditure, and the forthcoming earnings releases from Microsoft and Meta are seen as pivotal tests of returns on AI investments.

In other developments, the Federal Reserve is set to convene its policy meeting on July 28–29, with rate-hike probability rising to approximately **32%**, keeping a cautious tone across markets. Signs of easing US-Iran tensions sent crude oil tumbling over **6%**, with Brent falling below **$90** per barrel.
