President Donald Trump said the stock market drove his decision to back the Iran deal, calling it more brilliant than anybody as equities hit record highs after Sunday's ceasefire agreement. He made the comments at a G7 conference in France, hours after announcing the agreement with Iran. Trump said share prices rose each time peace looked likely and fell whenever talks stalled, treating the market as a live referendum on his Middle East strategy. The S&P 500 closed at a record 7,554.29 on June 15, up 1.65%, while the Dow added 468.77 points for its own record finish near 51,671 and the Nasdaq jumped 3.07%. He also argued the market held up better than he feared during the strikes on Iran, saying he thought the stock market would go down 25% or 30% but it was higher than when the strikes started, which he said shows a very resilient economy.
