TORONTO, Nov 12 (Reuters) - Toronto's main stock index fell on Thursday as soft oil and gold prices sent shares of heavyweight energy and mining companies lower.
The broader energy and materials sectors dropped 1.4 percent and 1.7 percent respectively, as U.S. oil prices CLc1 fell to below $77 a barrel, while gold edged off the record high it hit early on Thursday as the U.S. dollar recovered from recent lows. [O/R][GOL/]
"It's right across the board. The Canadian dollar is a little weaker on the back of the commodity market being a bit weaker, which is on the back of the U.S. dollar being stronger," said Bruce Latimer, a trader at Dundee Securities.
Investor sentiment was also slightly bruised by a guarded earnings outlook for the crucial Christmas quarter from retail giant Wal-Mart (WMT.N), casting doubt about the strength of consumer spending in the economic recovery. [ID:nN12404234]
"It certainly is a bit of a negative edge over the market," said Latimer. But he added he's seeing "some good volumes in some names," which could mean people are buying on dips.
The S&P/TSX composite index .GSPTSE finished down 78.99 points, or 0.69 percent, at 11,360.76, with six of its 10 main groups lower.
