All shares on the heavy OMXS30 list rose. High up on the winner list were several large industrial companies such as Atlas Copco, Sandvik, and SKF, with increases of 6-8 percent.
Wednesday's big loser, Electrolux, a white goods manufacturer with extensive exports to the USA, rose 5.9 percent.
The stock exchanges on Wall Street surged between 8 and 12 percent after Trump announced on Wednesday evening Swedish time that the USA would partially suspend import tariffs against the rest of the world, with the exception of China.
Despite Thursday's rise in Stockholm, the OMXS has fallen 9.5 percent since the turn of the year. And after the massive crash last week when Trump dropped the tariff bomb, the Stockholm stock exchange is still down 8.6 percent.
Leading European stock exchanges also rose sharply. The DAX index in Frankfurt, for example, rose over 5 percent.
The USA's import tariffs are far from gone. Among other things, the tariffs on EU cars, steel, and aluminum remain, plus a basic tariff of 10 percent. Thus, the USA still has historically high tariffs against the rest of the world, and the risk of an American recession is not over, writes news agency Bloomberg.
