TORONTO, July 29 (Reuters) - Toronto’s main stock index closed sharply lower on Friday, though off the one-month low it hit earlier in the day, as weak economic data and the U.S. debt crisis pushed investors to the safety of the sidelines.
The materials sector posted the biggest drop, down 1.28 percent, followed by the financials group, which fell 0.93 percent.
Royal Bank of Canada (RY.TO) was the top heavyweight decliner, down 1.3 percent at C$51.40. Next came fertilizer producer Potash Corp POT.TO, down 1.9 percent at C$55.16, and miner Goldcorp (G.TO), which dropped 2.2 percent to C$45.69.
The gold mining sub-group fell 1.3 percent, even as gold prices rose to new highs on weak economic data and fears of a U.S. default.
“Gold stocks are stocks, and right now everybody is being fairly cautious,” said John R. Ing, President of Maison Placements. “There’s fear of a pullback, so people are saying ‘let’s wait for the pullback’.”
The Toronto Stock Exchange’s S&P/TSX composite index .GSPTSE ended the session down 102.15 points, or 0.78 percent, at 12,945.63, after falling to its lowest level since June 27 earlier in the session. Eight of the 10 main index sectors finished lower.
The index was down 4.1 percent for the week, and 2.7 percent for July.
