The ADP private sector employment report showed that 156,000 jobs were added in April. The number fell way below the 196,000 jobs estimated by economists who were surveyed by Reuters.
The report is a precursor to the more comprehensive government nonfarm payrolls data, which is expected on Friday.

Eight of the 10 major S&P sectors were lower, with the financial index's 0.93 percent loss leading the decliners.
