United Technologies shares were down 7.7% after the defense contractor reported a mixed quarter. Net income of $1.81 a share beat analysts' estimates by a dime, while revenue of $16.33 billion fell 5% and missed estimates by $190 million. The company warned that future profit at its aerospace and elevator businesses would be lower than expected for 2015.

Harley-Davidson downgraded 2015 guidance for shipments of motorcycles to 281,000 at the high end, below a previous forecast of 282,000 at the low end.
