CommSec analyst Juliette Saly said investors were positioning ahead of the release of major company reports later in the week.

"We had a positive start, but it was encouraging to see the market push through that 5000-point level . . . in early trade despite the fact that we saw falls on US and Europe markets overnight."
Rio Tinto, Commonwealth Bank, Wesfarmers and Westfield are due to report later in the week.
"There's a lot of hope that these results will be better than what analysts had predicted," she said.
