Trading in the U.S. index futures suggests that Wall Street may start the week on a nervous note after stocks braved rate hike fears last week. However, setting a negative tone to the unfolding week is the Chinese trade data, which showed exports declining for four straight months and imports plunging, a sign of weak domestic data. Meanwhile, German trade data was fairly robust, tempering some of the negativity. The dollar is giving back some gains but commodities are mixed. In the absence of any major domestic trigger, overseas worries may create anxiety among domestic traders.
