US stocks edge up on higher oil prices, Walmart deal

New York - Wall Street stocks opened slightly higher on Monday, adding to records as oil prices rose and Walmart Stores edged up on news of its acquisition of online retailer Jet.com.

Oil prices advanced as the Organisation of Petroleum Exporting Countries said it would hold informal talks next month, potentially signaling tougher action in response to weak oil prices.

Walmart gained 0.2% after announcing a $3.3bn purchase of Jet.com, part of its efforts to counter Amazon in the booming e-commerce market.

Five minutes into trade, the Dow Jones Industrial Average was at 18 555.24, up 0.1%.

The broad-based S&P 500 added 0.1% at 2 184.65, while the tech-rich Nasdaq Composite Index gained 0.1% to 5 224.87.

The S&P 500 and Nasdaq finished at records on Friday following a better-than-expected US jobs report.
