US equity futures were little changed pre-bell Tuesday as traders awaited data on factory orders and job openings.

Dow Jones Industrial Average futures were 0.2% lower, S&P 500 futures were down 0.2%, and Nasdaq futures were 0.1% lower.

Oil prices were higher, with front-month global benchmark North Sea Brent crude up 0.7% at $65.30 per barrel and US West Texas Intermediate crude 0.8% higher at $63.29 per barrel.

The factory orders bulletin, scheduled for release at 10 am ET, is expected to show a 3.1% drop in factory orders for April following a 4.3% gain in March. Job openings based on the Labor Department's Job Openings and Labor Turnover Survey are seen falling to 7.11 million for April from 7.192 million previously, according to estimates compiled by Bloomberg.
