|US stocks open higher following gains in Asia and Europe
U.S. stocks rose in early trading on optimism that policymakers in Asia will do more to help boost growth in the region. Japan's stock market logged its biggest gain in almost seven years after comments from the country's Prime Minister raised expectations of more measures to shore up economic growth.
