Arista Networks, Inc.

Arista Networks is the AI-networking switch supplier of choice for hyperscalers and the enterprise data-center refresh. The stock broke out nearly 10% in a single session toward the $175 zone, completed a multi-month cup-and-handle base, and is now within 1% of its all-time high — with the option flow and insider selling both confirming the setup.

• The mechanics are exceptional even by AI-hardware standards: Q1 revenue grew 35% year-over-year at a 43% operating margin, zero debt, and growing net cash — this is a business that funds its own growth while returning capital.
• The AI-networking demand is being pulled forward: hyperscaler Ethernet-fabric buildouts are the specific volume story that drives Arista into $200+ territory, and the +8% breakout day plus the top-S&P-500-performer-of-the-day tag is the market confirming that reads.
• The option flow is putting money where the story is: $200 whale calls dated Aug 7 and heavy July $175 call buying is size positioning ahead of Aug 4 earnings, and it's aligned with the technical breakout the crowd is watching.
• Bechtolsheim's $42.7M sale is the honest counter-signal: the co-founder converting that size on a breakout is exactly the kind of print value-buyers should note, even when it's a small share of holdings — layered on top of a 20x sales multiple, it's the reason the stock isn't already at $200.

The Aug 4 print is the acid test — hyperscaler-driven revenue growth staying above 30%, gross margin holding near 64%, and any dated 800G/1.6T ramp color decide whether the breakout extends or becomes a distribution top. A clean beat with a raised guide and $200 comes into range fast; a hyperscaler-order pause or a margin miss and the -10% air pocket back to the 50-day at $160 fills quickly.
