Why ASML Holding (ASML) fell 4.33%
ASML Holding (ASML) fell 4.33% on November 5, 2026 — Tech selloff; weak Qualcomm, Arm results weigh.
What happened
ASML fell 4.3% as Asian chip stocks slid after disappointing earnings from Qualcomm and Arm. The move came from the sector selloff, not from any ASML-specific news.
Why it moved
ASML sells lithography tools to chipmakers, so its shares move with the group when investors reprice the whole semis cycle. Weak results from major chip names raise doubts about future equipment orders across the sector.
Why it matters
ASML is the bellwether of the Chip Supply Chain theme, where equipment demand rode the AI capex wave. This selloff tests whether that spending wave is still broad enough to lift the equipment makers.
What would break the thesis
If the sector rebounds on steadier chipmaker guidance, ASML should recover with it. A further cut in chip capex plans would deepen the pressure.
