Early indications suggest that Wall Street stocks may open Friday’s session on a nervous note, as the global markets have made another leg down amid risk aversion that is still intact. Commodities continue to be beaten down and the dollar is firmer. With limited Main Street activity, Asian stocks closed mostly lower, although Japan found a savior in a weaker yen. The European markets are also languishing deep in the red. Some key domestic economic data on retail sales, producer prices and consumer sentiment could set the tempo for today’s trading, as these may have implication for monetary policy ahead of next week’s FOMC meeting.
