(Dan Himbrechts/AAP PHOTOS)The ASX is trading near record highs as investors bet on a positive earnings season. Ten of 11 local sectors rallied, with strong performances from banks, miners and technology stocks despite oil prices inching higher as Iranian officials denied US claims the nations were in peace talks. Health care stocks also soared, gaining 2.4 per cent with particularly strong performances from CSL and Pro Medicus. Consumer-facing sectors inched higher after household spending rose 0.8 per cent in July, easing from 1.2 per cent in May but beating forecasts. The Australian dollar is buying 70.14 US cents, down from 70.27 US cents on Monday at 5pm AEST.
