周二盘中，机器人送货服务公司Serve Robotics Inc.（股票代码：SERV）股价出现大幅下跌，截至报道时间跌幅达5.11%，引发市场关注。
导致股价下跌的主要原因可能是分析师评级的下调。据悉，Seaport Research Partners将Serve Robotics的投资评级从"买入"下调至"中性"。这一评级变动可能引发了投资者对公司未来发展前景的担忧，从而导致了股价的大幅下跌。
值得注意的是，Serve Robotics专注于开发最后一英里配送服务的下一代机器人。该公司设计、开发和运营基于人工智能驱动的机器人移动平台，为公共场所提供低排放的配送服务。根据最新数据，Serve Robotics在过去5个交易日中下跌了1.42%，今年至今的跌幅达到23.11%。然而，过去60天内该股仍录得14.95%的涨幅，显示出一定的波动性。
