Vicor is trading at $242.25, down 4.44% in pre-market, with no clear fresh company-specific catalyst identified.

  • No announcement, earnings release, filing, or analyst action clearly explains the August 18 decline.
  • Recent Q2 results and AI-backlog commentary are stale context, not a confirmed catalyst.
  • Vicor rose 7.99% to $253.50 on August 17; Nasdaq 100 futures were down 0.68%, but evidence is insufficient to attribute causation.
