TORONTO (Reuters) - Canada's main stock index edged higher on Friday as commodities rallied and global worries about Britain voting to leave the European Union next week abated.
Still, the index fell 1 percent for the week and has pulled back 3.8 percent from a recent 10-month peak as markets became jittery ahead of Britain's referendum.
Reasonable earnings, economic recovery and low interest rates are supportive of stocks, but lack of clarity about the outcome of the referendum and related volatility may restrain investors near-term, said Irwin Michael, portfolio manager at ABC Funds.
"People don't want to hold anything that could have some speculation or risk to it," he said.
Canada's currency will weaken and the chances its central bank cuts interest rates would jump if Britain votes next week to leave the European Union, strategists warn, noting the result could hit global growth and spell bad news for commodity-exporting countries.
The Toronto Stock Exchange's S&P/TSX composite index .GSPTSE closed up 19.36 points, or 0.14 percent, at 13,901.77. But just four of the index's 10 main groups ended higher.

Oil prices rose for the first time in a week as the dollar fell and investors in global markets cautiously bought some riskier assets. U.S. crude oil futures CLc1 settled up $1.77 at $47.98 a barrel.
