TORONTO, June 14 (Reuters) - Canada’s main stock index fell for a fifth straight day on Tuesday, hitting a three-week low as financial and resource stocks retreated ahead of Britain’s vote on whether to leave the European Union.
The heavyweight financials group fell 1.0 percent as worries about a potential British exit saw investors push Germany’s 10-year bond yield below zero for the first time.
Opinion polls show growing support for Britain to leave the EU, which investors worry could tip the bloc into recession.
“The market is reacting to that in quite a negative fashion,” said Elvis Picardo, vice president of research at Global Securities.
Recent focus on Canada’s potentially overheated housing market has also been a headwind for financials, Picardo added.
“It raises concerns among investors about the extent of the exposure that the banks have to the mortgage business in Canada,” he said.
Royal Bank of Canada fell 1.8 percent to C$77.11 and Toronto-Dominion Bank declined 1.2 percent to C$55.86.
The Toronto Stock Exchange’s S&P/TSX composite index closed down 109.65 points, or 0.78 percent, at 13,884.23. The index hit its lowest since May 19 at 13,855.48.
Seven of the index’s 10 main groups ended lower.
The materials group, which includes precious and base metals miners and fertilizer companies, lost nearly 2 percent as concern about the global growth outlook offset a nearly six-week high for gold.
Spot gold edged 0.2 percent higher as rising Brexit fears supported safe-haven assets such as gold, while investors expected that the Federal Reserve will delay any U.S. interest rate hike again at its meeting that ends Wednesday.
Energy stocks fell 0.3 percent, pressured by lower oil prices.
Enbridge Inc fell 1.5 percent to C$53.39, while U.S. crude oil futures settled 39 cents lower at $48.49 a barrel.
The telecommunications group was one of the few that advanced, rising 0.9 percent. It included a 1 percent advance in the shares of BCE Inc to C$59.12.
