US stock futures edged higher on Thursday after President Donald Trump announced a 100% tariff on imported semiconductors, excluding companies manufacturing within the US. The move, aimed at boosting domestic production, sparked mixed reactions in markets. In after-hours trading, Apple jumped over 3% after pledging to invest an additional $100 billion in US companies and suppliers over the next four years. That followed a 5.1% surge during Wednesday’s regular session. On Wednesday, the Dow rose 0.18%, the S&P 500 added 0.73%, and the Nasdaq Composite advanced 1.21%, driven by strong corporate earnings. Sentiment was also buoyed by rising expectations of a Fed rate cut in September, with odds climbing above 93% after weaker labor data. However, renewed trade tensions added a note of caution after Trump imposed a 25% tariff on Indian goods in response to New Delhi’s continued imports of Russian oil.
