Canada's main stock index dipped on Tuesday as metal miners came under pressure for a second day, but the benchmark was on course for an eighth straight quarter of gains helped by a resilient economy and easing geopolitical tensions.

The Toronto Stock Exchange's S&P/TSX Composite Index TSX:TSX was down 0.1% by 10:08 a.m. ET, still on track to register its longest quarterly winning streak since January 1995-October 1996.

  • The benchmark index was poised for a 6.3% gain in the second quarter of the year, lagging behind U.S. peer S&P 500 CBOE:SPX, which is on track for a 14% gain.

  • "The Canadian market, for the most part, has been largely earnings driven," said Angelo Kourkafas, senior global investment strategist at Edward Jones Investments.

  • "It has lagged U.S. and some other indices because of its commodities tilt. But markets are ready to enter a new quarter from a solid footing."

  • The rally in oil prices due to the Middle East conflict helped Canada's energy index TSX:TTEN outperform other sectors with a 25% jump this year.

  • But crude prices have retreated sharply in recent weeks on signs of progress in ending the conflict, weighing on Canada's commodity-heavy stock index. Brent crude ICEEUR:BRN1! prices edged up to $73.29 on Tuesday.

  • Gold miners, part of the broader basic materials index which has a 16% weight in the TSX, came under pressure as spot gold prices headed for their worst quarter since 2013.

  • Investors will keep a close eye on U.S. economic data this week, including the June non-farm payrolls report, for clues on the Federal Reserve's monetary policy path.

  • Canada's economy rebounded more than expected in April, data showed, following a slight contraction in the previous month.

  • U.S. President Donald Trump's administration is expected to formally declare on Wednesday that it will not extend the U.S.-Mexico-Canada Agreement (USMCA) on trade, starting a decade-long clock to wind down the 32-year-old North American free trade zone as the three countries haggle over proposed changes.
