美国股市周三早盘走高。7 月通胀数据缓和后,市场对美联储继续加息的担忧有所降温。科技板块成为主要推动力,英伟达和多只 AI 概念股上涨,带动标普 500 和纳指走强,但道指表现相对偏弱。

通胀数据缓和预期

数据显示,美国 7 月 CPI 环比上涨 0.1%,同比上涨 3.4%。剔除食品和能源后的核心 CPI 环比上涨 0.2%,同比增速从 6 月的 2.6% 放缓至 2.5%。

这份数据缓解了此前因能源价格走高引发的通胀担忧。市场随之提高了对美联储 9 月维持利率不变的押注。美联储在 7 月底将基准利率维持在 3.50% 至 3.75% 区间,但当时有三名官员支持加息 25 个基点。

英伟达与芯片股领涨

截至美东时间上午,标普 500 指数上涨约 0.3%,纳斯达克综合指数涨幅更大。科技板块一度上涨 1.2%,费城半导体指数上涨约 3%。

个股方面,英伟达早盘上涨约 2% 至 3%。美光科技上涨 4.4%,博通上涨 1.4%。AI 基础设施公司表现更强,CoreWeave 在上调全年营收、营业利润和资本支出预期后,股价一度上涨超过 20%;Super Micro Computer 在给出高于预期的 2027 财年营收指引后,股价上涨超过 16%。

  • 英伟达盘中接近 223.8 美元
  • CoreWeave 积压订单升至 1042 亿美元
  • Super Micro 上调远期营收预期

英伟达下一项重要催化剂是 8 月 26 日公布的财年第二季度业绩。市场将继续观察 AI 支出是否维持高位,以及加速计算需求能否延续。

上涨集中在少数板块

虽然主要股指走高,但上涨并未全面扩散。早盘一度只有 179 只标普 500 成分股上涨,11 个板块中仅 4 个板块走高,反映出本轮反弹主要集中在科技和芯片股。

道指表现也弱于标普 500 和纳指。与此同时,道琼斯运输平均指数走弱,与工业指数之间出现背离。按照传统道氏理论,这类背离会削弱趋势确认力度,但目前更接近预警,还不能视为明确转向。

接下来,市场将关注 8 月 13 日公布的美国 7 月 PPI 数据,以及美债收益率变化。当前 2 年期美债收益率约为 4.18%,10 年期美债收益率约为 4.66%。从盘面看,通胀降温和 AI 板块强势仍在支撑美股,但市场强势主要集中在少数龙头股票。
