汽车租赁公司安飞士（Avis Budget Group，股票代码：CAR）今日盘中股价大跌5.15%，引起了市场的广泛关注。
消息面上，此次股价下跌主要与多家金融机构下调其评级并发出风险警告有关。近期，安飞士股价因极端轧空行情和租车需求激增的预期经历了史诗级上涨，过去六周内累计涨幅超过400%。然而，巴克莱银行（Barclays）已将其评级从“中性”下调至“减持”或“卖出”，德意志银行（Deutsche Bank）也从“买入”下调至“持有”。这些机构普遍认为，当前股价已严重偏离公司基本面，近期的暴涨主要由技术性因素（如流通股稀缺引发的空头挤压）驱动，缺乏基本面支撑，因此提醒投资者警惕回调风险。
知名投资者迈克尔·伯里（Michael Burry）也公开评论，认为此轮上涨纯属投机运气。市场分析指出，在股价经历如此大幅度的非理性上涨后，机构评级的下调和风险提示很可能触发了部分投资者的获利了结或风险规避行为，从而导致股价在盘中出现显著回调。
