ANET — Sep 195/215 call spread

Arista closed the week up 3.6% while the DC supply-chain basket fell 3.4%, one of only three non-hyperscaler names in the index that finished green. IV rank is 12.5, near the bottom of its 52-week range, so the 195/215 call spread costs 6.36 against 20 points of width and breaks even at 201.36, well inside the 8.4% move the chain prices. Broadcom's September 2 print and the Goldman Communacopia conference on September 8 both set the AI back-end fabric read before this expiry.

Signals

  • Week return vs basket: +3.57% vs supply-chain basket -3.44% (DB)
  • IV rank (52w percentile): 12.5, expected move 8.4% (DB)
  • Networking sector 1Y return: +213.4% avg across 7 tracked names (DB)
  • Tracked hyperscaler projects: OpenAI 3,895 MW, Meta 3,372 MW, Microsoft 1,000 MW (DB)

What invalidates this thesis

Broadcom using the September 2 call to claim custom-ASIC share in back-end switching would reset Arista's Ethernet narrative, and anything below 195 at expiry leaves the 6.36 debit worthless.
