Arista shares closed at $216.74 on October 9, up 2.73% for the session and 65.4% year-to-date, trading within 5% of the 52-week high of $217.41. A separate Form 144 filing on October 9 indicates a proposed sale of an additional 130,553 shares, acquired via a 2008 stock option exercise, also referencing the November 2025 trading plan.
The consistent selling pattern under a pre-arranged plan raises the question of whether the current 10b5-1 schedule will be fully executed or modified as the stock hovers near its yearly peak.
