Stock indices traded mixed on speculation the U.S. GDP will be stronger in the second quarter and due to increased mergers-and-acquisitions activity.

The U.S. GDP dropped 2.9% in the first quarter, missing expectations for a 1.7% decline, after a 1.0% decline the previous quarter. That was the worst performance in five years.

Market participants also expect the Federal Reserve will keep interest rates unchanged for a longer period.
