On July 17, Arista Networks fell 3.74% in regular trading, trading at $157.83/share, with turnover of $163 million. The decline was driven by sustained insider selling pressure from top executives and broad weakness across the communication equipment sector.

On the executive selling front, CEO and Board Chairperson Jayshree Ullal has cumulatively sold approximately 1.49 million shares across six separate transactions over the past three months, with the most recent sales on July 9-10 totaling over 460,000 shares at prices around $187-189 per share. Co-founder and Director Andreas Bechtolsheim also sold 220,000 shares in late May. The persistent large-scale insider selling has weighed heavily on market sentiment.

Meanwhile, the communication equipment sector faced broad selling pressure, with Applied Optoelectronics down 7.79%, Lumentum down 7.38%, Ciena down 7.20%, and Nokia down 4.76%. Despite recent analyst upgrades — TD Cowen raising its target to $210 and Wells Fargo lifting its target to $200, both maintaining buy ratings — the combination of executive selling signals and sector-wide weakness has driven the stock lower from $187 levels just one week ago.
