TUESDAY – U.S. stock index futures pointed to a slightly higher open on Tuesday, as investors remained watchful over the recovery in U.S. crude, ahead of important economic data.

For the U.S.’ first trading day of the week after Labor Day, oil is expected to keep investors abuzz after leading oil producers Russia and Saudi Arabia agreed on Monday to cooperate on stabilizing the energy market.

On the data front, the final Markit services PMI is due out at 9.45 a.m. ET, followed by the ISM non-manufacturing data, set to come out at 10 a.m. ET.

The data will be of key importance for the U.S., as investors look for indications as to how well the U.S. economy is performing. The data come just days after a disappointing jobs figure for the U.S. In August, nonfarm payrolls increased by 151,000, below what Wall Street economists were expecting of 180,000.

When it comes to earnings, Marvell Technology posted quarterly results before the bell Tuesday. Dave & Buster’s Entertainment and Casey’s General Stores are also expected to release their latest earnings.

European stocks traded slightly higher, while Asia-Pacific indexes finished mixed to higher overnight.
