Stocks opened slightly lower Friday as first-quarter GDP was revised down to negative 0.7% in a second estimate, from an original rise of 0.2%. The contraction was slightly narrower than economists had expected. Exports fell 7.6%, while imports were revised up to 5.6% from 1.8%, leading to a larger trade deficit which reduced GDP. Meanwhile, crude oil prices were rising more than 1% on Friday after U.S. inventories fell for the fourth week in a row.
