Why Taiwan Semiconductor (TSM) fell 1.87%
Taiwan Semiconductor (TSM) fell 1.87% on October 31, 2026 — Intel's results and AI spending doubts drag chips lower.
What happened
TSMC fell 1.9% in the AI Compute selloff, which followed a 975-point Nasdaq drop tied to Intel's results and renewed worries about AI spending. The decline was group-wide rather than driven by TSMC news.
Why it moved
TSMC manufactures the leading-edge chips that AI accelerators depend on, so its outlook is tied to the same hyperscaler spending the market was questioning.
Why it matters
TSMC is the manufacturing backbone of the AI Compute theme, and the theme's multi-month run was built on continuous GPU and accelerator demand.
What would break the thesis
A rebound in AI chip sentiment would likely restore the move quickly, since TSMC's volume visibility is strong.
