On Friday, S&P futures rose as President Donald Trump stated the Iran war “should be ending pretty soon.” At a Las Vegas event on Thursday, he said the conflict was “going along swimmingly.” Trump spoke hours after Israel and Lebanon agreed to a 10-day ceasefire. S&P 500 futures rose 0.2%, while Nasdaq 100 futures rose 0.1%. Dow Jones Industrial Average futures gained by 158 points, or 0.3%.

All three major indices climbed on Thursday, with the S&P 500 and Nasdaq Composite reaching fresh highs. The achievements came after Trump announced Israel and Lebanon authorities consented to the ceasefire. Trump said earlier this week that the Iran battle is “very close to over” and that Tehran wants to “make a deal very badly.”

Stocks rose on hopes of a peace accord, with the three major averages all rising this week. The Dow rose 1.4%, the S&P 500 3.3%, and the Nasdaq 5.2%.
