Power Integrations is trading 4.07% down at $53.06 after semiconductor stocks weakened broadly on August 28, 2026, following Marvell Technology’s disappointing timeline for revenue from its Google AI-chip agreement.

  • Marvell fell more than 7%, while SOXX declined 2.64% during regular trading, prompting profit-taking across chip stocks despite strong results.
  • No new company-specific negative announcement was identified; the August 5 earnings release and August 27 Nvidia-driven optimism were earlier developments.
  • The move is classified as sector-driven, with medium confidence.
