CHPX is trading at $99.00, up +1.63% in after-hours trading; no company-specific announcement explaining the rise was found.

  • Reuters reported that U.S. chip stocks fell amid competition concerns after reports of Chinese memory-chip maker CXMT’s technology progress, alongside jitters about AI spending.
