Overview
- Global equity markets fell this week after a sell‑off in semiconductor and AI‑exposed stocks knocked major indexes down and sent the PHLX semiconductor index into or toward bear‑market territory.
- Taiwan Semiconductor Manufacturing’s strong profit report was eclipsed by a jump in its full‑year capex guidance, which spooked investors who worried about the scale and timing of AI infrastructure spending.
- Netflix’s weaker‑than‑expected third‑quarter revenue forecast deepened the rout by hitting tech sentiment and adding fresh selling pressure on U.S. markets.
- Escalating U.S.‑Iran strikes lifted oil prices and risk premia, and extreme volatility in South Korea prompted authorities to curb leveraged, derivative‑based ETFs tied to major chip names.
- The move reverses a concentrated rally driven by expectations of large data‑center and memory demand, and it raises the risk that AI capital spending will be re‑priced if expected returns fail to materialize.
