美国时间周二（11月4日）盘后，网络设备制造商Arista Networks（ANET）股价大幅下挫10.86%，引发投资者广泛关注。这一跌幅可能与该公司刚刚发布的第三季度财报有关。
在正常交易时段，Arista Networks股价已下跌1.9%。分析师此前预计该公司第三季度营收将同比增长24%至22.5亿美元，每股收益为0.71美元。然而，盘后股价的剧烈下跌暗示公司的实际业绩可能未能达到市场预期。
值得注意的是，Arista Networks今年以来的股价表现强劲，累计上涨约40%，远超标普500指数15%的涨幅。该公司的股价在10月29日还创下了收盘新高。然而，近期股价的市盈率已达到49倍，远高于过去5年33倍的平均水平，这也引发了一些投资者对其估值的担忧。
市场普遍关注Arista Networks在人工智能驱动的以太网交换机和路由器需求方面的表现。此次财报可能未能满足投资者对公司在AI相关业务增长的预期，从而导致股价大幅下挫。具体财报数据及公司未来展望还有待进一步披露。
