The Australian share market is expected to start the trading week higher, after an encouraging end to the latest session on Wall Street.

But the market is likely to be volatile in the week ahead as uncertainty remains around a number of global issues, including the United Kingdom’s Brexit deal.

The futures market suggests the benchmark S&P/ASX200 will rise by about 0.3 per cent, or 17 points, when Australian trade resumes on Monday.

That comes after US stocks finished mostly higher on Friday, after an erratic day of trading ended with an 11th-hour buying spree.

The S&P 500 index rose 6.07 points, or 0.2 per cent, to 2,736.27, while the Dow Jones Industrial Average gained 123.95 points, or 0.5 per cent, to 25,413.22.

CommSec chief economist Craig James said the positive end to the week on Wall Street and rises in commodity prices bode well for the local market on Monday.

‘There’s a lot holding in our favour,’ he told AAP

Where things go from there remains less less clear, as several uncertainties remain, Mr James said.

They include the UK’s Brexit deal, as Prime Minister Theresa May defends her draft plan against fierce critics.

Investors are also watching trade tensions between the US and China, Italy’s spar with the European Union over its 2019 budget, and whether the US central bank is preparing to pause its rate-hiking cycle.

‘I don’t think we’ve seen an end to the volatility. We’ve seen pretty amazing volatility in the United States within the sessions,’ Mr James said.

‘When you do have a few uncertainties around the place, you have a diversity of views, and I think that’s what we’re seeing at the moment.’

Closer to home, investors will be keen to hear what Reserve Bank Governor Philip Lowe has to say when he addresses the Committee for Economic Development of Australia’s annual dinner on Tuesday.

The central bank will release the minutes from its November board meeting on the same day.

The Australian share market closed marginally lower on Friday, with the S&P/ASX200 down 5.4 points, or 0.09 per cent, to 5,730.6.

The Australian dollar was buying 72.68 US cents on Friday at 1630 AEDT.
