The Commerce Department report showed the economy grew slower in the first quarter than previously estimated, after downward revisions to consumer and equipment spending and a key measure of inflation ticked lower, ahead of Friday's personal consumption expenditure report for April.
"Normally you'd expect the market to rally off of a downward revision to GDP because it signals the economy is moderating, the Fed's job is done, we can get rate cuts. That's not the reaction we're getting today," said Mark Hackett, chief of investment research at Nationwide.
"So I'm a little surprised but not that surprised simply because after the six week (rally) that we've had, it's pretty healthy and expected to see some consolidation or sideways move for a while."
