美国最大健康保险公司联合健康集团（UnitedHealth Group）股价在盘前交易中大跌6.24%，引发市场广泛关注。这一跌势主要受到两大因素影响：公司高层突然变动以及可能面临的刑事调查。
据报道，联合健康集团首席执行官安德鲁·威蒂（Andrew Witty）因个人原因突然辞职，原董事长斯蒂芬·海姆斯利（Stephen Hemsley）重新执掌公司。同时，公司因医疗成本飙升而暂停了年度业绩预测，引发了投资者对公司未来发展方向的担忧。
更令市场震惊的是，《华尔街日报》报道称，美国司法部正在调查联合健康集团在其医疗保险优势（Medicare Advantage）业务中可能存在的刑事欺诈行为。尽管联合健康表示并未获悉任何正在进行的新调查，但这一消息无疑加剧了市场的不确定性。知情人士透露，这项调查至少从去年夏天就已经开始，重点关注公司记录触发额外付款的诊断结果的做法。
