AI BOOM. STOCK CRASH.
Key Takeaways
• Nasdaq −5.52%; S&P 500 −4.36%; Dow −3.44% on November 5.
• Semiconductor index fell more than 12% as investors repriced data-center growth.
• AMD Q3 revenue rose 45%; data-center sales rose 97%, but revenue growth and shareholder returns are not identical.
• Qualcomm fiscal Q4 QCT revenue fell 8% year over year, demonstrating uneven chip-market demand.
• US initial jobless claims were 189,000; one equity selloff is not itself evidence of recession.
