Canada's main stock market eked out a slight gain to end Tuesday's trading, as it stabilized from a steep decline Monday. Toronto Stock Exchange's S&P/TSX composite index added 0.14 percent, or 18.28 points, to close at 13,504.48 points after Monday's plunge caused by investors' concerns over the disappointing data from the world's two largest economies. The info-tech sector gained the biggest increase by 1.22 percent, with BlackBerry going up 5.56 percent to close at 10.64 Canadian dollars (about 9.61 U.S. dollars) per share. Shares of Bombardier went up to 4.05 Canadian dollars, while shares of Canadian Natural Resources gained 2.30 percent to 36.98 Canadian dollars apiece. The S&P/TSX Global Gold Index regained some ground by rising 0. 68 percent, with Goldcorp Inc. going up 1.24 percent to 27.82 Canadian dollars and China Gold International Resources Corp. Ltd. soaring 4.43 percent to 3.30 Canadian dollars. The retailer shares were weighed when Loblaw, the Canadian retailer giant, was down 0.17 percent to 42.32 Canadian dollars, after the world's biggest retailer, Walmart, announced that it is to spend 500 million Canadian dollars on 35 supercenters, which will create 7,500 new jobs. Walmart said its long-term plan is to offer groceries in each of its Canadian stores, a move that will increase the pressure on its retail rivals. On currency front, the Canadian dollar moved up to 0.9026 U.S. dollar Tuesday, compared with 0.8998 U.S. dollar in Monday's trading.
