The Globe and Mail reports in its Friday edition that U.S. stocks advanced on Thursday, as negotiations toward a peaceful resolution to the six-week Middle East conflict helped ease worries over the fragile U.S.-Iran truce. A Reuters dispatch to The Globe says that all three major U.S. stock indexes gained ground after rebounding from an earlier dip as Israel sought talks with Lebanon. Canada's main index, however, struggled to get out of the red and ended lower for the first time in seven sessions. Some of the more heavier-weighted names in the S&P/TSX Composite Index, including Shopify and Telus, were down sharply. The Canadian benchmark ended down 142.86 points at 33,477.71. Energy stocks struggled, with oil prices seesawing throughout the session, as markets waited for Iran to reopen the Strait of Hormuz. BlackBerry was a standout, adding 7.4 per cent. "There's an increasing recognition that [the Trump] administration is more bark than bite, and willing to make grand statements about world destruction," said Oliver Pursche at Wealthspire Advisors in New York. The Dow rose 275.88 points to 48,185.80, the S&P 500 gained 41.85 points to 6,824.66 and the Nasdaq composite gained 187.42 points to 22,822.42.
