Trading in the U.S. index futures suggests that Wall Street stocks may open Friday’s session on a down note following a 3-session winning streak. Meanwhile, trading activity could be light, given the extended weekend due to July 4th public holiday. After Asian stocks closed mostly higher, the European markets are seen holding onto their modest gains, courtesy positive manufacturing activity data and stimulus hopes. Commodities and currencies are mixed. The domestic markets could also track the ISM’s manufacturing PMI data and a Fed speech scheduled for the day.
