Why GigaDevice (GIGADEV) fell 9.46%
GigaDevice (GIGADEV) fell 9.46% on July 29, 2026 — China roadblocks hit memory chip stocks.
What happened
GigaDevice, a Chinese flash and microcontroller player, fell in tandem with the sector as SanDisk and peers hit China roadblocks, signaling broad export uncertainty.
