Of the 30 most traded stocks on Stockholm's OMXS30 list, 26 fell. Heat pump manufacturer Nibe lost 5.1 percent. Measurement technology company Hexagon, technology trading company Addtech and industrial conglomerate Lifco fell 4.2–4.6 percent.
"It is reasonable that we will have a negative market reaction to everything that has happened this weekend, with US threats of tariffs and countermeasures from the EU. With stock markets that are relatively highly valued and new highs recently, it is natural that there will be profit-taking," says Maria Landeborn, senior strategist at Danske Bank to TT.
The Wallenberg sphere's investment company, Investor, fell 3.7 percent. On the other hand, the defense group Saab, with Investor as a major owner, rose 2.2 percent.
Mild in comparison
At the close in Stockholm, the stock exchanges in Frankfurt, London and Paris were also clearly in the red. The New York Stock Exchange is closed on Monday.
Monday's fall is also mild compared with April last year, when Trump launched his broad tariff plan and the Stockholm Stock Exchange fell by around 3.5 percent.
"Tariffs were higher and applied to virtually all countries in the world, so it came as a shock to the market. Since then, many trade agreements have been concluded at lower levels and we know more about trade policy today than we did then," says Landeborn.
She also mentions what has come to be known as "Taco", that is, "Trump always chickens out" - loosely translated.
Advice: Take it easy
The term was coined after the market saw that Trump's tariff threats were usually withdrawn when, for example, American interest rates rose as a consequence.
"If we start to see the same thing again - that is, countries selling US bonds, interest rates going up and we get a broader stock market crash - then I think the market is counting on Trump having a pain threshold. He has shown that time and again in the past year," says Landeborn.
For small savers, the downturn may feel unnerving, but Jon Arnell, investment manager at von Euler & Partners, pointed out the classic advice when TT spoke to him:
"I think you have to try to be long-term and stick to your savings plan," says Arnell.
Gold and silver prices hovered around new record levels on Monday.
