Arista Networks has the joint-second-highest score in the live scanner universe at 93, reports on a listed November 3 date with 11 days to go, and is down about 16.4% over roughly the past month. The reason it is down is that on October 22 the semiconductor complex fell 6.72% and Arista fell 7.19%. Arista builds the switches that connect AI clusters. It does not fabricate wafers. The connection to that selloff was narrative, not supply chain.
The Month in Detail
Arista closed at $181.19 on October 20, rose to $184.33 on October 21, then dropped to $171.07 on October 22 as the sector broke. It has recovered slightly to about $172.77 intraday on October 23. Over roughly the past month that is a decline of 16.35%.
Put that next to the rest of the infrastructure group over the same stretch. Vertiv is down about 24%, Seagate about 30%, Lam Research about 27.9%, KLA about 21.8%, and the iShares Semiconductor ETF 16.1%. Arista at 16.35% fell in line with the semiconductor complex, which is exactly what a narrative-sold name does, and it is a useful contrast with the mega-cap software and cloud names that barely moved.
The Scanner Numbers
The live scanner has Arista at a score of 93, a price of $169.92 and a market cap of $214.31B. Thirty-two analysts cover it with 7 strong buy, 24 buy, 1 hold and 0 sell, so 31 of 32 are non-negative. Short interest is 1.1% of float, earnings sentiment reads Positive, and the implied-volatility reading is 76.5.
A score of 93 with only one hold and no sell ratings is one of the cleanest books in the universe. Arista is the networking layer of the AI buildout, and the fact that it scores 93 while carrying a 16% monthly drawdown is the tension in this setup: the analyst view has not broken, but the price has.
The Targets
The scanner's target ladder for Arista is $174.88 at 3 days, about 2.9% above the current price. The 7-day target is $184.80, about 8.8% above. The 14-day target is $194.72, about 14.6% above. The implied-volatility reading is 76.5.
That 14.6% fourteen-day figure is worth looking at next to the price. If Arista simply regained its October 20 level of $181.19, that is about 6.6% from here and roughly halfway to the 7-day target. Retaking the October 21 high of $184.33 would be about 8.5%, essentially the 7-day target. So the mid-range targets are, in effect, a reversion-to-recent-levels scenario rather than a new-high scenario.
Why Networking Is a Cleaner Read Than Wafers
If you want to know whether the AI buildout is intact, networking is arguably a cleaner read than semiconductors, for a simple reason. A wafer constraint delays chips. A networking constraint shows up as clusters that are built but underutilised, because the switches are not there yet. Arista's revenue tracks how much compute is actually deployed and connected, not how much is ordered.
That distinction matters given what NVIDIA CEO Jensen Huang said at GTC Berlin on October 22, describing neocloud demand as off the charts, the same morning the sector sold off. If demand for deployed compute is extraordinary, then the constraint Lam Research described is a supply problem, and supply problems resolve differently than demand problems. They compress timing rather than eliminate the buildout.
Arista reporting in 11 days into a sector that has just been repriced on a supply constraint is a genuine information event. The question it answers is whether the networking layer is seeing the same constraint, or whether it is insulated from it.
How Arista Compares With the Rest of the AI Infrastructure Layer
Arista's 16.35% monthly decline is worth comparing against the names around it. Vertiv is down about 24%, Seagate about 30%, KLA about 21.8%, Lam Research about 27.9%, Micron about 20.1%, and the iShares Semiconductor ETF 16.1%. Arista fell almost exactly in line with the semiconductor complex.
Now put it against the names that barely moved. IBM rose on October 22 and is up about 8.3% over a month. Tesla fell 3.08% on the day and is down only about 1.5% over a month. Microsoft is up 1.02% over a month. Alphabet is down 5.97%. Arista at 16.35% sits in the gap between the two groups, which is where a mid-cap infrastructure name with genuine AI exposure and no semiconductor fabrication of its own belongs.
That middle position is the reason the score is 93 while the price is down 16%. The analyst view did not break and neither did the sentiment reading. The price broke because the category it trades inside broke.
What the Analyst Book Does and Does Not Tell You
Thirty-two analysts with 7 strong buy, 24 buy, 1 hold and no sell is 31 of 32 non-negative, which is about 97%. That is the cleanest book on the board. Arista has 7 strong buy ratings, the highest strong-buy count of any name discussed this week apart from Amazon's 16 out of a larger 60-analyst book.
What a clean book cannot tell you is when the price recovers. Analyst positioning describes the view, not the flow. Short interest at 1.1% means there is no borrow-driven element in either direction, and a $214.31B market cap means there is no meaningful squeeze mechanic. The support underneath this stock is the analyst view and the business, not the positioning.
The Valuation Question the Print Has to Answer
Arista's revenue tracks how much AI compute is actually deployed and connected rather than how much is ordered, which makes the October 28 print a partial read-through on the AI buildout for the whole complex. Alphabet, Microsoft and Amazon all report within a week of it, so the market will get four data points on the buildout inside eight days.
The setup question is narrower than that. Arista fell 7.19% on October 22 while SOXX fell 6.79%, so it fell slightly more than the sector despite having no wafer exposure at all. That relative underperformance, in a name whose analyst book is the cleanest on the board, is what the November 3 print has to resolve.
Key Takeaways
- Arista scores 93 with 11 days to a listed November 3 print, at $169.92 and a $214.31B market cap.
- It fell 7.19% on October 22 against a 6.79% fall in SOXX, and is down 16.35% over roughly a month.
- Thirty-two analysts cover it with 7 strong buy, 24 buy, 1 hold and no sells, and short interest is only 1.1%.
- Implied volatility reads 76.5, with targets of $174.88 at 3 days, $184.80 at 7 days and $194.72 at 14 days.
- Regaining the October 20 level of $181.19 is roughly the 7-day target, so the mid-range case is reversion rather than a breakout.
What to Do Next
Arista offers the cleanest expression of AI infrastructure demand in the universe that is not a mega-cap, with a score of 93 and an analyst book that has not broken despite the drawdown. The catch is an 11-day window and a 76.5 implied-volatility reading, which means the premium is real and the position needs to be sized for a wide reaction.
Use the 3-day target of 2.9% to size short-dated structures, and watch whether the semiconductor complex stabilises from its October 22 lows. Arista's drawdown was narrative-driven, so a stabilising tape is the condition under which that drawdown most likely reverses.
