Arista Networks stock falls 1.10 percent after S&P 100 entry

Arista Networks stock was trading at USD 204.27 on the NYSE on September 28, 2026, down 1.10 percent at 10:55 a.m. ET. The move follows the networking company's addition to the S&P 100, while its latest quarterly figures continue to show rapid expansion.

S&P 100 membership raises visibility

S&P Dow Jones Indices announced on September 4, 2026, that Arista Networks would enter the S&P 100 before trading opened on September 21, 2026. The official table identifies Arista Networks and ticker ANET as an addition in the Information Technology sector.

The index change gives Arista a larger benchmark profile at a time when investors are measuring networking suppliers against the capital spending cycle for artificial intelligence data centers. The market value stood at USD 257.2 billion on September 28, 2026, based on the latest intraday quote.

Revenue reaches USD 3.04 billion

MarketBeat reported that Arista's second-quarter 2026 revenue reached USD 3.04 billion, up 37.7 percent from the same quarter a year earlier. The report also cited quarterly EPS of USD 1.02 against a USD 0.89 consensus estimate and third-quarter 2026 EPS guidance of USD 1.06-1.08.

That combination puts the current share-price reaction into perspective: operating execution remains strong, but the stock is still being judged against elevated expectations. The key comparison is growth against valuation discipline, not growth alone.

Wells Fargo target reaches USD 255.00
