Trading in the U.S. index futures suggests that Wall Street stocks may open Friday’s session, the last of a lackluster week, on a negative note. As the dollar firms up amid chatter about a June rate hike, most commodities are higher. However, oil is moderately lower. Among the global markets, Asia closed lower and the European markets are currently moderately lower. The retail space could see weakness following disappointing results from Dillard’s and Nordstrom. The domestic markets may also focus on domestic data on retail sales, producer prices for final demand and consumer sentiment.
