Arista Networks is trading 3.1% down at $195.50 after opening the August 18, 2026 pre-market session below the August 17 close of $201.80, amid broad technology and risk-off pressure.
- No fresh company-specific negative announcement was identified; Arista is scheduled to participate in the Rosenblatt Age of AI Technology Summit later August 18.
- Sector down 1.52%; Nasdaq futures lower, yields rising and geopolitical tensions heightened. Positive recent second-quarter results and outlook limit evidence of an earnings-driven decline.
