Investors are hopeful of a good day trading on the Australian share market after US technology companies gained good results and optimism grew about a US-China trade deal.

The SPI200 futures contract was up 32 points, or 0.47 per cent, to 6873.0 points at 0800 on Tuesday following a good mood on US markets where Apple, Facebook, Netflix, Microsoft and Amazon posted strong results.

A US-China trade agreement, expected to be signed in Washington on Wednesday, has encouraged riskier bets.

An easing of Middle East tensions between the US and Iran, which traded strikes in the region this month, has also helped investor confidence.

The Australian share market on Monday pulled back after breaking through all-time highs last week.

Some of Australia’s largest companies had the biggest price drops.

The Australian dollar was buying 69.06 US cents, down from 69.15 US cents at Monday’s close.
