The Globe and Mail reports in its Friday edition that U.S. and Canadian stocks ended mixed on Thursday after paring deeper losses, as diplomatic signals from the Middle East helped calm markets rattled earlier by U.S. President Donald Trump's threats of tougher action against Iran. A Reuters dispatch to The Globe says investor sentiment steadied in the afternoon after Iran's Foreign Ministry said it was drafting a protocol with Oman to manage traffic through the Strait of Hormuz and Britain said dozens of countries were discussing ways to end the crisis. Oil prices ended the day sharply higher. Front-month crude prices surged, with U.S. crude up 11 per cent at around $111 a barrel, while Brent closed up 7 per cent near $108. October trade, however, is priced at about $82. For the week, the S&P 500 gained 3.36 per cent, Nasdaq rose 4.44 per cent and the Dow climbed 2.96 per cent. The S&P/TSX Composite Index ended up 150.27 points at 33,108.22. For the holiday-shortened week, the Toronto Stock Exchange was up 3.6 per cent, which was its biggest weekly gain since November. Energy gained 2 per cent. Shares of Rogers Communications lost 7.9 per cent after TD Cowen cut its rating and price target on the stock.
