 Stocks opened mixed this morning as the Commerce Department reported slightly faster economic growth in the first three months of this year. NPR's Scott Horsley reports the Dow Jones Industrial Average fell about five points in early trading. Revised figures from the Commerce Department show the U.S. economy grew at an annual rate of 1.4 percent in January, February and March. Consumer spending was a little bit weaker than had been reported, but government spending and business investment were a little bit stronger. Imports were also revised down.
