标准普尔/澳交所200指数周五下跌0.2%，至8760点以下，扭转了前一交易日的涨幅，因美国总统唐纳德·特朗普宣布新关税打击了市场情绪。从10月1日开始，美国将对品牌和专利药品进口征收100%的关税，在美国建厂的公司除外。特朗普还宣布对橱柜和浴室梳妆台征收50%的关税，对卡车征收25%的关税，并于当天生效。在悉尼，医疗保健行业在公告发布后损失最大，行业巨头CSL和Telix Pharmaceuticals各下跌近3%。此外，科技股继续下跌，Wisetech（-2.8%）和Xero Limited（-1.5%）领跌，在收益率上升的情况下，华尔街科技股连续第三天下跌。与此同时，重量级矿商股价上涨0.8%，在大宗商品价格上涨的情况下限制了跌幅。本周，该指数有望第四周下跌，部分原因是对澳大利亚储备银行政策宽松的预期降低。

The S&P/ASX 200 slipped 0.2% to below 8,760 on Friday, reversing the prior session’s gains, as sentiment was hit by US President Donald Trump’s announcement of fresh tariffs. Starting October 1, the US will impose a 100% tariff on branded and patented pharmaceutical imports, with exemptions for firms building plants in the US. Trump also unveiled tariffs of 50% on kitchen cabinets and bathroom vanities and 25% on trucks, effective the same day. In Sydney, the healthcare sector suffered most losses following the announcement, with sector majors CSL and Telix Pharmaceuticals down nearly 3% each. Additionally, technology stocks extended losses, led by Wisetech (-2.8%) and Xero Limited (-1.5%), tracking a third straight day of declines in Wall Street tech shares amid rising yields. Meanwhile, heavyweight miners rose 0.8%, capping losses amid higher commodity prices. Over the week, the index is on track for its fourth weekly decline, partly due to trimmed expectations of RBA policy easing.
