Key numbers explained

• Price: 203.47 USD, down -0.84% today, with a 52-week range of 114.52 – 214.89 — the stock has gained 43.9% over the past year and trades near the top of its yearly range.

• Return on equity of 31.5% and a price-to-book ratio of 17.34 — strong profitability on shareholders' capital, but the shares trade at a high multiple of book value.
• Beta of 1.62 — the stock has historically moved more sharply than the broad market, so it tends to be more volatile than an average S&P 500 constituent.

Recent news

Headlines have contrasted Arista with Cisco, noting that Cisco sank 6% while the tech sector rose and Arista held flat, and debating whether Cisco looks expensive relative to its own guidance. A fund commentary mentioned realizing gains in the high-speed switch leader, and another piece asked whether Arista stock has quietly become a different bet. Other coverage touched on networking-sector peers, including HPE's networking orders and Nomios expanding in Southern Europe.

What to watch

As a networking supplier to cloud and AI data centers, Arista's results are sensitive to data center and AI infrastructure spending by large cloud providers. Its high valuation multiples mean the stock can react sharply to changes in revenue growth or margin expectations. Competition from larger networking rivals and shifts in enterprise and government IT budgets are also relevant. The next earnings date is Nov 3, 2026.
