Overview
- The so-called Magnificent Seven erased about $800 billion in combined market value following July 23's earnings session, with Tesla plunging roughly 14–15% and Alphabet falling about 7%.
- The selloff was triggered by guidance that raised AI capital spending, with Alphabet disclosing a much larger 2026 capex range and Tesla calling 2026 a “massive capex year.”
- Money rotated into component suppliers as investors sought nearer-term beneficiaries of AI demand, sending memory-chip names such as Micron and SanDisk higher while large builders fell.
- Policy and energy shocks intensified the rout as President Trump’s new Section 301 tariffs took effect and oil briefly topped $100 a barrel, increasing inflation concerns ahead of next week’s Federal Reserve meeting.
- Market implications include greater scrutiny of growth valuations, a closer focus on supplier earnings and GPU supply chains, and heightened volatility around upcoming reports from Microsoft, Meta, Apple and Amazon.
