Nikkei jumps 4.9% as Japan GDP revised up.

Japan has revised its annualized Q1 GDP reading to 4.1% from an initial reading of 3.5%, helping to send the Nikkei (EWJ, DXJ) up 4.9%. A strengthening of the dollar against the yen following U.S. payroll data on Friday also helped boost stocks. However, Barclays warned that the GDP revision "should not be viewed as a reflection of economic strength," as it was mainly due to a quirk in the way the data is calculated.
