The Dow Jones Industrial Average closed at a record high on Thursday, 12 June. The S&P 500 posted its biggest single-day gain since April. Oil prices hit their lowest level since March. All of it traced back to one announcement: the United States and Iran had agreed to end their war.
On Sunday, Trump declared the deal 'now complete' in a Truth Social post late Sunday. Markets responded positively on Monday morning, with futures rising sharply ahead of the open. According to CNBC, Dow futures added 440 points, or 0.9%, while S&P 500 futures climbed 1.14% and Nasdaq 100 futures rose 1.79%.
