World shares are on the rise today following a vote of confidence from the Fed on Wednesday that the U.S. economy was on track. The Dow and S&P surged yesterday to their strongest percentage gains of the year on the news, following Janet Yellen's comments that an interest rate increase was unlikely for at least the next two FOMC meetings. Whether hikes come sooner, faster, or on that date, said Yellen, depends on the incoming data.
