At the close, the broad S&P500 index had risen 0.8 percent, the technology-heavy Nasdaq's composite index 0.6 percent and the Dow Jones industrial index 1.1 percent.
This meant, among other things, that the S&P500 once again closed at a new record level – for the eleventh time this year.
Risk willingness was triggered by the USA's new agreement with Japan, which means 15 percent import duties on Japanese goods in the USA.
Agreement near with EU
Additionally, Trump said that an agreement with the EU is near, a prediction that was immediately reinforced by the Financial Times, citing sources, stating that Washington and Brussels are close to an agreement on 15 percent tariff levels.
Exceptions will be made, among other things, for aircraft, spirits and medical technology products.
Agreements are in place with Indonesia, the United Kingdom and Japan – and more are expected to be near before the pause expires at the end of July.
Successful tariff policy
Louis Navellier, founder and investment manager at the consulting firm Navellier&Associates, says that Trump's heavily criticized tariff policy so far appears to be successful in the form of, among other things, large investments in the USA.
They have not yet caused the disruptions and inflation that the opponents said were certain, says Navellier to CNBC.
After the market close, investors will be keeping an eye on the electric car company Tesla and Google owner Alphabet. Then they – as the first of the large, index-heavy technology companies – will submit their reports for the second quarter of the year.
Tesla rose 0.1 percent ahead of the report, while Alphabet fell 0.6 percent.
