Advanced Micro Devices is trading at $456.59, down -3.52%, as semiconductor stocks decline broadly ahead of Nvidia’s August 26 earnings.

  • Samsung Electronics fell more than 8% after investors were disappointed by its shareholder-return plan, intensifying sector weakness.
  • The broader chip sell-off reflects valuation concerns, profit-taking, and reduced exposure before Nvidia’s report; no fresh company-specific catalyst was identified.
  • The decline follows recent weakness after Advanced Micro Devices’ August 4 outlook failed to satisfy elevated AI-growth expectations.
