ANET enters the back half of August with an unusual setup: a stock trading 35% below where most of its analysts think it belongs, yet with short sellers adding to positions at the fastest pace in months.
The post-earnings analyst reaction was one of the more uniform responses seen in networking this cycle. Following Q2 results on August 4, every major firm that covered the stock raised its target. Barclays went furthest, lifting to $289 from $195. Wells Fargo and UBS moved to $255 and $259 respectively. Morgan Stanley pushed to $220. The consensus direction was unanimous — all raises, all maintained positive ratings — and the Street's aggregate target now sits comfortably above $240, implying roughly 26% upside from the current $190.94. Bulls point to Arista's entrenched position with hyperscalers like Microsoft and Meta, expanding exposure to AI-driven data center builds, and a campus enterprise opportunity that adds a second growth vector. The bear case rests on supply constraints that could crimp second-half revenue and competition from Cisco, whose proprietary stack keeps some enterprise accounts sticky.
The short-seller activity is the contrarian note. Short interest climbed 13.5% in a single session on August 25, pushing the weekly change to roughly 12.5% and bringing the position to 1.0% of free float — still low in absolute terms, but the direction of travel is worth flagging. More telling is the context: short interest spent most of July above 17 million shares and peaked near 22 million in mid-July. It then collapsed 40% through early August, coinciding with the earnings beat. The rebuild this week looks like fresh skepticism after the post-earnings pop rather than a structural short thesis. Borrow conditions support that read — cost to borrow has fallen 35% over the past week to just 0.33%, and availability is essentially unlimited, meaning there is no friction at all for anyone who wants to add a short position. The ORTEX short score sits at 28.9, modest relative to the factor universe.
Options positioning adds a mild layer of caution. The put/call ratio is running at 0.87, above its 20-day average of 0.83 and roughly 1.3 standard deviations elevated — not an alarm, but a tick toward defensiveness. The ratio peaked at 0.91 earlier in the week before easing back. The 52-week range runs from 0.62 to 1.05, so the current level sits in the upper third without approaching extremes. Together with the short rebuild, it suggests a pocket of the market is hedging against a stock that has already retraced 1.2% on the week despite a 1.5% bounce on August 25.
The recent earnings history is constructive. The August 4 print produced a 6.7% one-day move and held most of that gain into the five-day window, finishing the period up 7.0%. The prior quarter showed an even sharper pattern — up 8.1% on the day, extending to 10.3% by day five. Two consecutive post-earnings rallies of that magnitude leave the stock with a high bar to clear at the next event, currently scheduled for November 2. Institutional ownership remains concentrated, with founder Andreas Bechtolsheim still holding 14.4% of shares outstanding, though filings show a trim of 1.5 million shares. CEO Jayshree Ullal also reduced her position by 2.2 million shares as of mid-August. Recent insider activity on the books is limited to small director-level award grants and one modest open-market sale — nothing that shifts the ownership narrative materially.
The November earnings date is now the clearest focal point: the question worth tracking is whether the short rebuild deepens ahead of that print, or whether the uniform analyst conviction draws buyers back to close the gap between $190 and a consensus target north of $240.
