On September 22, Arista Networks rose 3.13% in regular trading, trading at $205.275/share, with turnover of $518 million. The rally was driven by the official inclusion of Arista Networks in the S&P 100 Index, which took effect on September 21.

S&P Dow Jones Indices previously announced the quarterly rebalancing of both the S&P 100 and S&P 500 indices, with Arista Networks among the new additions to the S&P 100 alongside Palo Alto Networks, SanDisk, and Dell. The inclusion means passive funds tracking the S&P 100 benchmark are required to allocate corresponding positions, generating incremental buying demand that provides near-term support for the stock price.

Fundamentally, the company reported strong Q2 results in early August, with adjusted EPS of $1.02 beating the consensus estimate of $0.89, and revenue of $3.04 billion surpassing the $2.83 billion expected. Q3 guidance of approximately $3.3 billion in revenue also exceeded the $2.95 billion analyst forecast, underscoring robust demand for its AI-related networking equipment from major clients including Microsoft and Amazon.
