The Globe and Mail reports in its Tuesday edition that North American stocks recovered from an early dip in the first day of trading since the United States and Israel launched attacks against Iran over the weekend. The Globe's David Berman writes, however, that rising gold and oil prices, as well as a move into the safety of the U.S. dollar, suggested some investor anxiety over how long the conflict will last and whether it could spread beyond Iran. The S&P 500 on Monday closed flat at 6,881.62, while the S&P/TSX Composite Index closed at 34,541.27, up 201.28 points. But beneath the relatively calm surface are several wild market gyrations, reflecting simmering concerns about trade, inflation and monetary policy when equity valuations are stretched. Overseas markets did not fare as well. The price of crude oil jumped 8 per cent, to $72.38 (U.S.) a barrel, amid threatened exports from the Middle East. Gold rose to $5,311.60 an ounce, up $63.70, though still shy of its record in late January. The U.S. dollar index, which measures the dollar's strength against a basket of currencies, rose 1 per cent, also suggesting investors are seeking safety from a conflict that could stretch for several weeks or more.
