The insider sales are tiny relative to company size and are accompanied by heavy option-exercise / tax-withholding activity typical of scheduled vesting events. No bearish signal. Monitor next earnings for fundamentals; these sales do not warrant a trade on their own.
Price Chart
Executive Summary
Arista President/CTO Kenneth Duda and Director Yvonne Wassenaar sold shares in open-market transactions totaling ~$2.07M from May 14–21, 2026. These sales are modest relative to ANET's $194B market cap (~0.001%), are overwhelmingly driven by option exercises and tax-withholding events (non-cash), and align with post-vesting liquidity patterns rather than informed bearish signals. The net cash outflow from open-market sales is negligible.
