当地时间8月21日，美股市场呈现出明显的下跌态势，三大指数全线收跌，标普500指数更是连续第五个交易日下跌。投资者在美联储主席鲍威尔即将于杰克逊霍尔经济年会上发表讲话前，保持着高度的谨慎态度，市场交投气氛趋于观望。

收盘时，道琼斯工业平均指数较前一交易日下跌152.81点，收于44785.5点，跌幅为0.34%;标准普尔500种股票指数下跌25.61点，收于6370.17点，跌幅达0.4%;纳斯达克综合指数下跌72.55点，收于21100.31点，跌幅同样为0.34%。

从大型科技股的表现来看，多数股票下跌。特斯拉、Meta跌超1%，苹果、微软、英伟达、奈飞、亚马逊、AMD、英特尔等均小幅下跌，仅谷歌实现小幅上涨。科技板块作为年内推动美股上行的关键力量，近期面临着获利回吐的压力，其较高的估值引发了部分投资者的抛售行为。

在热门中概股方面，多数股票呈现上涨态势，纳斯达克中国金龙指数收涨1.35%。其中，小鹏汽车表现亮眼，涨幅近12%。小鹏汽车公告称，公司联合创始人、执行董事、董事长、首席执行官兼控股股东何小鹏于2025年8月20日至8月21日通过全资拥有的GalaxyDynastyLimited在公开市场购买了310万股A类普通股，平均价为每股A类普通股80.49港元，这一举措可能对股价起到了提振作用。蔚来涨幅超9%，老虎证券、名创优品涨逾6%，爱奇艺、小牛电动涨逾2%。然而，中概股内部也存在分化，阿特斯太阳能跌逾18%，禾赛跌11%，哔哩哔哩跌超6%，晶科能源跌逾4%，大全新能源、阿里巴巴跌超1%。
