SMH holds diversified semiconductor and equipment-vendor exposure; as fab capex and wafer-process orders moderate and foundries slow expansions, the entire industry—from chipmakers to suppliers—faces order visibility…

## Why it matters

Chip Supply Chain theme: fab capex and wafer-process equipment orders have slowed sharply after quarters of AI-driven buildout, with foundries moderating wafer expansions and legacy chipmakers cutting spending—a…

## What would break the thesis

If hyperscaler capex rebounds or new AI inference demand accelerates, foundry capex could stabilize and SMH regains upside; a prolonged slowdown in advanced-node spending would keep pressure on the index.
