周四（8月14日）夜盘交易中，联合健康集团（UnitedHealth Group，股票代码：UNH）股价大涨10.50%，成为市场焦点。这一显著涨幅主要源于投资界传奇人物沃伦·巴菲特（Warren Buffett）旗下的伯克希尔哈撒韦公司（Berkshire Hathaway）披露新增持有该公司股票。
根据伯克希尔哈撒韦公司提交的最新13F报告显示，截至2025年6月30日，该公司持有约504万股联合健康集团股票，持股市值约为15.7亿美元。这一消息公布后，投资者对联合健康集团的信心显著提升，推动其股价在盘后交易中快速上涨。
值得注意的是，巴菲特此次重返联合健康投资阵营，距离其上一次持有该公司股票已有十多年之久。这一投资决策发生在联合健康集团面临诸多挑战的背景下，包括医疗成本飙升、联邦调查以及其子公司遭受网络攻击等问题。尽管如此，巴菲特的加入无疑为市场注入了一剂强心剂，提振了投资者对联合健康未来发展前景的信心。
