Trading in the U.S. index futures suggests that Wall Street stocks may open Tuesday’s session on an upbeat note, although lighter volumes associated with pre-holiday trade may not lend credence to any move. Commodities are moving back to the upside even as the dollar is mixed. Among the global markets, Asian stocks closed higher for the day, while the European markets are rallying strongly. The domestic markets may also keep an eye on economic data on house prices and consumer confidence.
