Trump took office on Monday. As the stock exchange on Wall Street was closed for the weekend, the first day with a new president meant rising prices.
The broad S&P 500 index rose 0.9 percent, the Dow Jones industrial index 1.2 percent, and the Nasdaq's technology-heavy composite index 0.6 percent.
Trump has made a rapid start on signing presidential decrees. However, regarding one of the largest sources of concern – the swift introduction of high import tariffs, which could lead to a global trade war – the market has quickly interpreted Trump as relatively restrained.
Other initial statements and expected initiatives from the president – such as investments in AI – have been seen as favorable for US companies.
The interest rates on American government bonds, regardless of maturity, fell sharply during the day – a sign of increased interest in stock trading.
In terms of individual stocks, industrial conglomerate 3M climbed strongly, with a 4.2 percent increase following a quarterly report with better-than-expected figures.
Tech giants Amazon and Alphabet (Google) also had a good day, with increases of 2.1 and 1.1 percent, respectively.
However, a sharp decline of 3.2 percent for the index-heavy iPhone manufacturer Apple held back the upswing.
The dollar continued to fall after previously being at its highest level in 13 months in January. One dollar now costs 10.99 kronor.
