On Friday, the U.S. markets rose as investor sentiment continued to be positive following the announcement of another round of quantitative easing by the Fed. Market confidence was lifted as the Fed announced Thursday an open ended QE3 focused on the mortgage-backed securities purchases to revive the economy. It also extended its conditional commitment to leave its policy rate at near-zero until mid-2015. This has given the signal to the markets that the Fed doesn't intend to withdraw its accommodative policy stance any time soon.
