Why ASML Holding (ASML) rose 5.18%
ASML Holding (ASML) rose 5.18% on July 31, 2026 — Amazon, Microsoft AI spending surge lifts chips.
What happened
ASML, the world's leading supplier of semiconductor lithography equipment, gained 5.2% as Amazon and Microsoft earnings confirmed sustained AI infrastructure capex, signaling continued fab tool demand.
Why it moved
ASML's extreme-ultraviolet (EUV) and advanced lithography tools are the bottleneck for cutting-edge chip fabs; hyperscaler capex confirmation directly translates to multi-year equipment orders, justifying higher…
