Early indications suggest that Wall Street stocks may pullback on Wednesday following yesterday’s rally. Among the global markets, Asian stocks had a mixed session, while the European markets are trading lower. Oil and most other commodities are lower, although the dollar has also come under selling pressure. Light volume could be the order of the day in the penultimate session of the year and the final full session trading day of the year. The markets may also keep an eye on the National Association of Realtors’ pending home sales data due for the day.
