Arm Holdings plc American is trading at $423.46 (+2.64%) as the stock extends its sharp AI-driven rally amid a broader risk-on tone in equities.

  • The move follows an 8.33% gain on June 15, supported by sustained demand for AI chips, upbeat analyst targets, and robust fiscal Q4 results.
  • With no new company-specific catalysts reported today, the advance appears to be driven by continued momentum in AI-exposed semiconductor names.
