US session for 06.02.2016

U.S. stock index futures pointed to a lower open on Wall Street Thursday morning as traders eyed the release of ADP payroll data, OPEC's meeting in Vienna, as well as comments from European Central Bank (ECB) President Mario Draghi.

The private sector ADP payroll report – set to come out at 8:15 a.m. ET – is not widely seen as a reliable indicator for the government's jobs report, expected Friday, but last month it reported just 156,000 jobs. Two days later, April nonfarm payrolls came in at just 160,000, 40,000 shy of expectations.

According to Thomson Reuters, 175,000 jobs are expected for May from ADP, while 162,000 nonfarm payrolls are expected in the government report Friday.

Elsewhere on the data front, initial claims are due at 8:30 a.m. ET. Traders will also be watching Federal Reserve Governor Jerome Powell, who speaks on regulation at 8:35 a.m. ET, and Dallas Fed President Rob Kaplan, who speaks at 1:00 p.m. ET at a conference at Boston College.

Traders will also be keeping a keen eye on OPEC's meeting in Vienna, which could impact the price of oil. The 13-member producer group is not expected to cut or freeze oil production at its meeting Thursday – ideas that failed at its last meeting in April. Brent crude traded at around $49.79 a barrel on Thursday morning, up 0.14 percent, while U.S. crude was at around $49.08, up 0.14 percent.

In Europe, ECB President Mario Draghi will speak at a press conference following a meeting of the Governing Council of the ECB. The pan European Stoxx 600 Index was down by around 0.02 percent on Thursday morning.

In Asia, Japan's Nikkei closed 2.32 percent lower on Thursday. In China, the Shanghai Composite closed 0.40 percent higher.

On the earnings front, Joy Global is set to report before the bell. Broadcom and Five Below are among companies set to report after the bell.
