US pre-open: Stocks seen touch lower as investors eye services data

At 1155 BST, Dow Jones Industrial Average, S&P 500 and Nasdaq futures were all down 0.1%. On Friday, all three indices ended at records despite the release of a disappointing non-farm payrolls report.

On the data front, Markit's composite and services PMIs are due at 1445 BST, while the ISM non-manufacturing PMI is at 1500 BST, along with factory orders.

Spreadex analyst Connor Campbell said: "While the Markit reading is set to creep from 53.1 to 54.1 month-on-month, the ISM figure is forecast to fall from 57.5 to 57.1."

Oil prices were in the red, reversing course after gaining earlier in the session on news that Saudi Arabia, Egypt, the UAE and Bahrain have cut diplomatic ties with Qatar, citing concerns about its terrorist links. West Texas Intermediate was down 0.3% to $47.51 a barrel and Brent crude was down 0.4% to $49.77.

Investors in the US were likely to be looking across the pond after a terror attack in London over the weekend left seven people dead and dozens injured. In addition, the UK general election on Thursday was also likely to be on investors' minds.

In currency markets, the dollar was down 0.2% versus the pound after the latest poll by ICM for The Guardian put the Tories 11 percentage points ahead of Labour. Although this is down from a 12-point lead in a poll published a week ago, it is still wider than in several other opinion polls and puts support for the Conservatives at 45%, with Labour at 34%.

On Thursday, former FBI head James Comey, who was fired by Donald Trump last month, will testify before the Senate Intelligence Committee on Russia’s role in the US presidential election.
