周四，标准普尔/多伦多证交所综合指数下跌约0.3%，至25100点以下，由于投资者吸收了最新的交易动态，第二个交易日延续了负面势头。美国总统特朗普宣布对进口汽车征收25%的关税，将于4月3日生效，并表示将于次日宣布互惠关税。此举抑制了早些时候对选择性关税豁免的希望，并警告称，如果欧盟和加拿大协调反制措施，“更大”的关税可能会针对它们。科技板块受到的打击尤其严重，Shopify（-3.4%）、Constellation Software（-0.8%）、CGI股份有限公司（-1.1%）和Celestica（-5.6%。

The S&P/TSX Composite Index fell around 0.3% to below the 25,100 mark on Thursday, extending negative momentum for a second session as investors absorbed the latest trade developments. U.S. President Trump unveiled a 25% tariff on imported vehicles, set to take effect on April 3, and signaled that reciprocal tariffs would be announced the following day. This move dampened earlier hopes for selective tariff exemptions and came with a warning that “far larger” tariffs could target the EU and Canada if they coordinated countermeasures. The tech sector was particularly hard hit, with Shopify (-3.4%), Constellation Software (-0.8%), CGI Inc. (-1.1%), and Celestica (-5.6%) all declining, while financials and energy producers also traded firmly in the red. However, gains in major mining equities—supported by higher bullion prices—provided some offset to the overall losses.
