美国运通（AXP）股价在盘前交易中大涨5.08%，引起市场关注。这一涨幅出现在摩根大通下调其目标股价的背景下，显示出投资者对该公司前景的信心仍然强劲。
据报道，摩根大通将美国运通的目标股价从325美元下调至244美元。尽管目标价有所下调，但新的目标价仍明显高于美国运通当前的股价水平，这可能是刺激投资者买入的一个因素。
值得注意的是，美国运通股票近期表现疲软，过去5个交易日下跌12.63%，今年以来累计下跌20.62%。今日的盘前大涨可能是对近期跌势的技术性反弹。此外，作为全球领先的金融服务公司，美国运通在信用卡和支付领域的强劲地位，可能也增强了投资者的信心。然而，市场仍需密切关注该股在正式交易时段的表现，以确认这一上涨趋势是否能够持续。
