Arista Networks is trading 3.63% up now at $198.47 as investors continue rewarding its August 4 second-quarter beat and higher 2026 outlook.

  • Reported its first quarter above $3 billion in revenue and raised full-year guidance to approximately $12.6 billion.
  • Strong AI-networking demand supported the outlook.
  • With the broader market nearly flat, the move appears primarily company-driven; the earnings catalyst remains the clearest explanation for the August 11 advance.
