Early indications suggest that Wall Street stocks may open Tuesday’s session higher, latching onto the commodity rally seen for much of the European session. Oil is up over half a dollar a barrel and the rest of the commodities are also in the green, as the dollar gives back some ground. The mood across the Atlantic is buoyant, as traders focus on commodities and strong German export data and in the process overlooked some disappointing earnings and data. Tame Chinese inflation data is also lending support.
