ANET · PEAD ↑ 43

Arista Networks reported Q3 2026 EPS of $1.11 on 2026-11-03, beating the $0.99 consensus by $0.12 (+12.1%).

Print-day reaction was +3.5% versus the prior close, as the market absorbed a clean EPS beat on the day of the report. The overnight gap to T+1 open extended a further +5.3%, signalling sustained buying pressure after hours rather than a fade. Day 1–3 drift then pulled back –4.3%, reversing a meaningful portion of the gap-fuelled gains as sellers stepped in over the subsequent sessions. Cumulative abnormal return of +6.3% versus SPY.US nonetheless keeps this in PEAD long territory; per the documented pattern, the read holds through 2027-01-29.
