Asian Chip Stocks Tumble as China Reports Breakthrough in Machine That Makes Microchips

Asian chip stocks fell 7.5% on July 28, 2026 — the worst day since March — after reports a Chinese state-backed firm began mass producing machines that print tiny circuits onto microchips. Samsung fell 13.4%, SK Hynix 14.7%. The technology could help China make chips on its own, threatening rivals. Whether the machines work well enough for real factory use remains unverified.
