Power Integrations is trading at $46.31, down 4.02%, amid semiconductor weakness after Lam Research’s outlook raised concerns about supply constraints and China revenue.

  • Related coverage reported Lam Research shares fell about 7% after its results.
  • Broader risk-off sentiment may also weigh on shares; major U.S. indices are lower and semiconductor stocks are down 3.64% pre-market.
  • No clear new company-specific news was found for October 22; the recent Ideal Power collaboration and analyst price-target change do not clearly explain the drop.
