Early indications suggest that Wall Street stocks may open Friday’s session on a nervous note, although the mood may be cemented by the monthly non-farm payrolls report scheduled to be released ahead of the market open. The jobless rate is expected to remain unchanged. Economists expect another month of healthy pace of hiring, with the Street numbers at 190,000. Meanwhile, Asian stocks ended mostly higher amid caution. The mood across the Atlantic is somewhat optimistic ahead of the jobs report. Crude oil prices are flat lining.
