Early indications suggest that Wall Street stocks may open Friday’s session notably higher, given the risk appetite set in motion by a surprise announcement by the Bank of Japan to adopt negative interest rates. Asian stocks lapped up the announcement with glee and the European markets are also bound northward, as hopes that central banks and governments will step in to support global growth had a calming impact. Oil is higher and the dollar is mostly higher. The domestic markets could also react to the earnings news flow and economic data on fourth quarter GDP, consumer sentiment and a regional manufacturing activity.
