受中东紧张局势有望缓解的消息提振，华尔街股市周三（4月22日）开盘走高。美国总统特朗普宣布延长与伊朗的停火协议，为市场注入了乐观情绪。
截至美东时间上午，道琼斯工业平均指数上涨0.93%，报49606点；标普500指数上涨0.82%，报7122点；纳斯达克综合指数上涨0.98%，报24497点。
特朗普在社交媒体上表示，应巴基斯坦方面的请求，美方决定延长停火，以便伊朗方面能提出统一的谈判方案。此举被视为冲突降级路径上的积极信号。
除了地缘政治因素，强劲的企业财报也为市场提供了支撑。波音公司（BA）公布的第一季度亏损小于预期，推动其股价上涨超过3%。数据显示，截至目前已公布财报的标普500成分股中，超过80%的公司业绩超出市场预期。
尽管市场对停火延长持欢迎态度，但分析指出，美伊谈判前景仍存不确定性，地缘政治风险尚未完全消散。
