9月11日，Arista Networks盘中上涨3.4%，报195.425美元/股，成交额3355.53万美元。
消息面上，标普道琼斯指数公司此前宣布将Arista Networks纳入标普100指数，调整将于9月21日正式生效。随着生效日临近，跟踪标普100的指数基金和ETF需按新成分股进行调仓，被动资金的买入预期对股价形成持续支撑。此次调整中，耐克、霍尼韦尔航空等传统企业被剔除，新纳入的四家公司均来自科技领域，标普100行业结构进一步向AI基础设施及数据中心网络方向集中。与此同时，高盛近日予公司"买入"评级，12个月目标价225美元；President Capital亦将目标价由180美元上调至238美元，维持"买入"评级，机构共识均价约250美元，反映市场对公司AI基础设施及企业园区部署需求前景的乐观预期。
