Factories have also been hit by the strengthening in the dollar last year,” said Stephen Stanley, chief economist at Amherst Pierpont Securities.

“Today’s data on both IP and retailing lean the same way, towards a softer second-quarter growth rate that will essentially cancel out the upside surprise we saw in first-quarter GDP,” said Avery Shenfeld of CIBC Capital Markets.
