ARM is trading at approximately $403.95, down 8.1% in pre-market action, extending a sharp pullback after last week’s powerful AI- and analyst-driven run-up.

  • The decline follows a period of intense momentum supported by bullish catalysts, including Bernstein’s recent price target hike to $500 tied to agentic AI prospects.
  • With no new company-specific headlines or earnings reports, the move appears to be driven by profit-taking amid a broader tech-led risk-off tone and weak index futures.
