TORONTO, April 25 (Reuters) - Toronto’s main stock index ended a three-day upswing on Monday as investors dumped Barrick Gold Corp ABX.TO, after it struck an all-cash deal to buy an Australian copper miner.
The Toronto Stock Exchange’s S&P/TSX composite index .GSPTSE unofficially ended down 64.70 points, or 0.46 percent, at 13,907.32. Six of the index’s 10 main groups were weaker, led by a 6.39 percent drop in the materials group, which fell on a steep selloff in gold-mining issues. The index’s gold subsector dropped 10.52 percent. (Reporting by Ka Yan Ng; editing by Peter Galloway)
