Key Price Behavior Insights: • Support holding • Resistance ceiling • Sharp pullback Support Level: $168-$169 Resistance Level: $182-$187 Over the last month, ANET remains slightly constructive, but it must defend $168-$169 and clear $182-$187 to resume the uptrend after the fast run to $186.96 and pullback to $168.61.

AI Summary

8.0
Positive

ANET is now best viewed as a direct AI infrastructure beneficiary with real product momentum and elite cash generation, but at ~51x earnings the stock already prices in success, so the key test is whether 1.6T switch adoption and hyperscaler demand can stay durable enough to justify further upside versus a consolidation/downside reset if AI capex slows.
