(Reuters) - Futures for Canada's main stock index inched higher on Thursday, supported by an uptick in gold prices and positive corporate earnings, while caution ahead of a U.S. jobs reading kept a check on gains.

September futures on the S&P/TSX index were up 0.4% at 6:48 a.m. ET (10:48 GMT).

The Toronto Stock Exchange's S&P/TSX composite index ended 0.5% lower on Wednesday and closed at its lowest since June 28.

The index opened strongly, boosted by a surge in e-commerce platform Shopify, but fizzled out on numerous challenges to the market outlook, including the winding down of yen-funded carry trades and persistently high U.S. interest rates.
