Lonsec client adviser Michael Heffernan said despite the declines so far on Friday the market was in a period of consolidation.
“The market is not going to go up every day, you can't expect that,” Mr Heffernan said.
“The fact that the market is only down 0.4 per cent early in the morning is a good effort after a lacklustre performance particularly in the US.”
