In a carbon copy of the previous session, US markets ended little changed overnight amid mixed economic data.

After being up for most the session, the Dow and S&P500 gave up all of their gains towards the final moments of trading. The Dow remained at 16073 and the S&P500 added one point to 1803.

The late sell-off was in response to data showing US consumer confidence tumbling more-than-expected in November due to the recent government budget fight.

It was different story on the Nasdaq, however, which managed to close above 4000 for the first time in 13 years. The index settled 23 points higher (+0.6%), at 4018.

Commodities were slightly weaker, with oil extending its declines ahead of tonight's US supply report, which is expected to reveal another increase in weekly crude stockpiles.

The US dollar was generally weaker against other currencies, largely due to the disastrous consumer confidence read.

The Aussie remained under pressure, however, after yesterday's comments from RBA deputy governor Philip Lowe alluded to another interest rate cut.

In economic news, construction work data is due for release at 11:30am, AEDT.
