Recent moves
Arista's Bechtolsheim sells 260,000 shares
The move
A Nov. 9 SEC filing shows Arista Networks co-founder Andreas von Bechtolsheim sold 260,000 shares of the company in 16 separate trades on Nov. 5, at weighted-average prices ranging from $159.11 to $171.45 per transaction. The filing says the sales were made under a Rule 10b5-1 trading plan he adopted on Feb. 20, 2026, through a family trust for which he is trustee. After the sales, the trust still held about 180 million Arista shares.
Why it matters
Pre-arranged trading plans like this one are routine and don't necessarily signal a change in view, but the size of the sale is a reminder of how much Arista stock is still concentrated with its founders.
The bear case
Because the sale was set up months in advance under a 10b5-1 plan, it says nothing about Bechtolsheim's current view of Arista's prospects.
What to watch
Arista's next Form 4 filings for signs the selling pace is changing.
Arista posts record revenue, raises full-year outlook
The move
Arista Networks reported third-quarter revenue of $3.66 billion, up 58.5% from a year earlier, with non-GAAP earnings of $1.20 a share versus a $1.08 estimate. The company raised its full-year 2026 revenue forecast to $13.3 billion, about 48% annual growth.
Why it matters
The raised outlook shows Arista's AI-driven networking demand still accelerating even as some rivals warn of slower data-center spending.
The bear case
Despite the beat, Arista shares briefly dropped in after-hours trading, with some investors reading the outlook as short of the bigger beat-and-raise they had expected.
What to watch
Arista's next quarterly report, expected in February, will show whether the raised full-year forecast holds.
Arista's Bechtolsheim sells more stock on a 10b5-1 plan
The move
Andreas Bechtolsheim sold 267,892 shares of Arista Networks (ANET) on Oct. 30 across eight trades, at weighted-average prices from $167.51 to $174.14, an SEC Form 4 shows. The sales were made under a trading plan he adopted on Feb. 20, 2026, leaving him with 180,275,156 shares held indirectly through a trust.
Why it matters
10b5-1 plans let insiders schedule sales months in advance, so the timing doesn't necessarily reflect a view on the stock today.
The bear case
Even routine, pre-scheduled selling by a company's largest insiders can weigh on sentiment if it continues for months.
What to watch
Further sales under the same plan.
Arista Networks posts fastest revenue growth since its IPO
The move
Arista Networks reported third-quarter revenue of $3.66 billion, above its own $3.3 billion guidance and up 58.5% year over year, with non-GAAP EPS of $1.20 versus $0.77 a year earlier and a 64% non-GAAP gross margin. The company raised its full-year 2026 revenue forecast to $13.3 billion and gave an initial 2027 target of about $18.5 billion, above the roughly $16.4 billion Wall Street had modeled. CEO Jayshree Ullal called it "another momentous quarter with the highest year-over-year revenue growth since our IPO" and said it reflects the company's "increased relevance for the generative and agentic AI era." Shares jumped after hours, with JPMorgan raising its price target to $270 from $250. Arista co-founder and largest shareholder Andreas von Bechtolsheim, through the Bechtolsheim Family Trust, holds about 14.6% of the company.
Why it matters
The networking gear that connects AI data centers together is turning out to be as sought-after as the chips inside them, and Arista's growth rate shows that demand isn't slowing.
The bear case
Arista has disappointed investors on margin or guidance details in several recent quarters despite beating estimates, so a strong headline number hasn't always translated into a lasting stock gain.
What to watch
Whether Arista's initial 2027 revenue target of about $18.5 billion holds up as the year progresses.
Arista falls 8.5% ahead of Nov. 3 earnings
The move
Arista Networks, co-founded by Andreas Bechtolsheim, fell 8.5% on Oct. 30 amid a broader technology-sector selloff, according to TradingKey. The stock had already dropped more than 18% from its Oct. 9 high as investors grew cautious about its premium valuation -- a forward price-to-earnings ratio of roughly 45 times estimated 2026 earnings -- ahead of its Nov. 3 results.
Why it matters
The drop shows how sensitive highly-valued AI-infrastructure stocks have become to broad market caution, even without company-specific bad news.
The bear case
The move came with no new information about Arista's own business, and investors will get a clearer read when the company reports earnings on Nov. 3.
What to watch
Arista Networks' Q3 earnings, due Nov. 3.
Bechtolsheim files to sell $45 million more Arista stock
The move
Arista Networks co-founder Andreas Bechtolsheim filed notice on Oct. 30 to sell 267,892 shares, worth about $45.2 million, under a trading plan he adopted in February 2026, according to an SEC Form 144 filing. It's one of several similarly sized sales under the same plan this year, including roughly $60 million worth of stock in both August and September.
Why it matters
The filing is a routine disclosure under a pre-set 10b5-1 trading plan, not a new decision -- but it shows one of Arista's largest holders has been steadily trimming his stake all year.
The bear case
A Form 144 is only a notice of intent to sell, not a confirmed sale, and Bechtolsheim remains one of Arista's largest shareholders.
What to watch
Arista Networks' Q3 earnings, due November 3.
