Early indications suggest that Wall Street stocks may open on a jittery note on Friday, as commodities continue to experience weakness. The dollar has been firmer, although the euro is seeing a small bounce upward as flash estimate revealed that inflation stayed in positive territory for the third straight month. The mood across the Atlantic is listless notwithstanding the release of mostly positive earnings. However, German retail sales eurozone unemployment data and U.K. consumer confidence data all were disappointing. The domestic markets may also be wary of the earnings news flow and economic data on regional manufacturing activity and consumer sentiment.
