# Why VanEck Semiconductor ETF (SMH) rose 1.67% on September 12, 2026

VanEck Semiconductor ETF (SMH) rose 1.67% on September 12, 2026 — ASML expands High-NA ties with Samsung, Intel on AI demand.

## What happened

The VanEck Semiconductor ETF tracked a modest Chip Supply Chain rally on ASML's announcement of expanded High-NA partnerships with Samsung and Intel, broadening confidence in industry capex cycles.

## Why it moved

SMH holds diversified equipment makers, chip designers, and foundries — all of which benefit from ASML's strengthened customer commitments, which signal sustained advanced-node demand and equipment spending.

## Why it matters

The semiconductor supply chain is entering a multi-year capex upcycle driven by AI; ASML's High-NA ties with tier-1 nodes validate that industry-wide infrastructure investment will remain robust.

## What would break the thesis

The ETF's modest move (1.5%) relative to leveraged peers reflects a diversified basket — if any major holding's capex cycle falters or geopolitical risk flares, the rally will fragment.
