美国股指期货周五上涨，前一交易日表现喜忧参半。周四，道琼斯指数下跌0.51%，标准普尔500指数下跌0.08%，纳斯达克综合指数上涨0.35%。情绪受到唐纳德·特朗普总统全面报复性关税的影响，该关税于午夜生效，税率从10%到41%不等。在特朗普澄清他对进口芯片征收100%的税将豁免在美国境内制造的公司后，半导体股表现优异。在政治发展方面，特朗普提名经济顾问委员会主席Stephen Miran接替Adriana Kugler进入美联储理事会。报道还表明，美联储理事克里斯托弗·沃勒是领导央行的主要竞争者，这增强了市场对9月降息的押注。

US stock futures advanced Friday following a mixed performance in the prior session. On Thursday, the Dow fell 0.51% and the S&P 500 slipped 0.08%, while the Nasdaq Composite rose 0.35%. Sentiment was shaped by the rollout of President Donald Trump’s sweeping retaliatory tariffs, which took effect at midnight and ranged from 10% to 41%. Semiconductor shares outperformed after Trump clarified that his 100% levy on imported chips would exempt firms manufacturing within the US. In political developments, Trump nominated Stephen Miran, chair of the Council of Economic Advisors, to replace Adriana Kugler on the Federal Reserve Board of Governors. Reports also suggested Fed Governor Christopher Waller is a leading contender to head the central bank, bolstering market bets on a September rate cut.
