Trading in the U.S. index futures suggests that Wall Street stocks may open Tuesday’s session notably higher, in line with the risk appetite that is picking up and benefiting risk asset classes. Earlier in the global trading day, Asian stocks closed mixed amid the release of weak Chinese export and import data, while the European markets are advancing strongly, buoyed by strong German trade data and M&A news. Most commodities are higher, although oil is slipping sharply. In the absence of any other major economic data, it remains to be seen if the markets can sustain the upward momentum, as indicated by the futures trading.
