At the close, the broad S&P 500 index landed at a plus of 1.0 percent, the technology-heavy Nasdaq's composite index increased 0.5 percent and the industrial index Dow Jones also increased 1.0 percent.
Earlier in the day, the broad S&P 500 index rose to record levels – and exceeded the previous high from February this year. After Trump's message, both S&P and Nasdaq fell.
The opening shone green in connection with the market welcoming new tariff messages from the US and China and hoping for more trade agreements for the Trump administration's part.
Trump's message about the cancelled talks with Canada came as a response to Canadian taxes targeting American tech companies. According to The Washington Post, it is about a 3 percent tax on revenues that major tech companies, such as Amazon and Google, receive from Canadian consumers.
"Based on this outrageous tax, we are terminating ALL trade discussions with Canada, effective immediately", Trump wrote on the platform Truth Social.
