The Globe and Mail reports in its Friday edition that Canada's main stock index rose on Thursday to a record high as copper prices jumped and investors grew optimistic that the U.S. Federal Reserve would resume its easing campaign. A Reuters dispatch to The Globe says that the S&P/TSX Composite Index ended up 185.63 points at 26,751.95, eclipsing Tuesday's record closing high. Wall Street also rose as the Israel-Iran ceasefire continued to hold and a raft of economic indicators appeared to support the case for the Fed lowering borrowing costs this year. The Toronto materials sector rose 1.7 per cent as the price of gold remained elevated and copper climbed more than 3 per cent. A three-year low for the U.S. dollar against a basket of major currencies gave copper a boost. Shares of copper producer Teck ended 7.9 per cent higher. Bank stocks outperformed after the Fed unveiled a proposal to relax its leverage rules, which would ease the capital that big banks are required to hold against relatively low-risk assets. "This administration came in promising deregulation," said Ross Mayfield at Baird in Louisville, Ky. "And this is not just an example of that, but kind of a signpost that there could be more to come."
