European bourses trade broadly lower, but a pullback seems overdue after European stocks have been trading at five-year highs; markets across Asia ended mixed.
It's still the thick of earnings season, but today's reports have made little impact on the broader market; GT Advanced Technologies +22% after announcing a partnership agreement with Apple.
Modest selling has Treasurys at session lows, with the 10-year yields up 2.5 bps to 2.627%.
Still ahead: ISM services index, more Fed speakers.
