Arista Networks stock drops 20% from October peak amid AI sector sell-off, still expected to beat Q3 revenue estimates.

Arista Networks shares have fallen nearly 20% from their October highs due to broad negative sentiment in the AI sector, not company-specific problems. The company is expected to report strong Q3 revenue of $3.3 billion, a 44% year-over-year increase, likely surpassing analyst expectations and continuing a 20-quarter growth streak. Despite solid growth and operational leverage, Arista trades at a high forward P/E ratio of 42-43x, making it expensive compared to other AI-related stocks like Nvidia and Broadcom. The recent price drop improves its value, but investors may find more attractive opportunities in other fast-growing AI stocks. The analyst remains neutral on Arista's stock for now.

Arista Networks shares are trading at USD 182.30 on Pluang as of Oct 19, 2026 19:31 WIB, showing a 3.01% gain in the last day. The stock's market capitalization stands at $223.21 billion, reflecting its significant size in the technology sector. Investors typically hold Arista shares for about 54 days on the platform, indicating moderate trading activity.
