TORONTO, July 16 (Reuters) - Toronto’s main stock index finished higher for a fourth-straight session on Thursday, as firmer commodity prices boosted the heavyweight resource sectors.
Takeover talk in the potash patch and rising gold prices encouraged strength in the materials group, which rose 1.4 percent, spurring gains in Canadian fertilizer stocks.
Potash Corp POT.TO, the biggest heavyweight gainner, rose 4.44 percent to C$102.33, while Agrium AGU.TO rose 5.4 percent to C$45.14.
A Brazilian newspaper reported Brazil’s Vale VALE5.SA VALE.N, the world’s largest iron ore miner, may bid for the fertilizer company Mosaic Co MOS.N.
Meanwhile, a number of other companies have been scouting for potash assets, and earlier on Thursday Canada’s Athabasca Potash Inc API.TO said it is exploring a possible sale of all or part of the company. [ID:nBNG199332]
