Duda Kenneth, President and CTO of Arista Networks (ANET), has filed 277 Form 4 transactions in a single company, and the pattern is one-sided. Across all filings, his total sell value is $107,584,901.49, with zero buy value and zero acquired value. The recent window shows 10 sell-related codes and no purchases. On August 20, 2026, he executed a cluster of open-market sales (code S) totaling roughly $6.2 million, with individual amounts ranging from $88,249.75 to $1,228,473.60. That same day he also had option exercises (code M) and a tax withholding event (code F) valued at $2,897,619.45, which is standard when shares are surrendered to cover exercise costs.
The most recent filings, dated September 10, September 8, and August 28, 2026, all carry code J, which is not a standard buy or sell designation and carries a value of zero. These are likely adjustments or other non-monetary events, not open-market activity. The last actual open-market sale occurred on August 20, and the August 28 and September entries show no dollar value, meaning they do not change the cash picture. Since the start of the recent period, there has been no code P (purchase) and no code A (grant), so the selling bias is clear.
The data shows a consistent disposition of ANET shares, but the August 20 sales were paired with option exercises, which is a mechanical pattern: exercise, sell to cover tax, and sell the remainder. The total sell value across all history is substantial, but the recent activity is concentrated in one day. There is no indication of buying conviction, as the buy count is zero. The next Form 4 will show whether the September code J events convert into sales or remain non-cash adjustments.
