Private payroll data from ADP showed hiring slowed to 152,000 jobs last month, far below the 175,000 economists polled by Dow Jones expected. The data is the latest sign of weakness in the labor market that investors hope will give the Federal Reserve enough evidence to cut benchmark interest rates.
Traders also regarded data on activity in the services sector. Business services PMI rose more than expected to 53.8 compared to an estimate from Dow Jones that called for 50.7. Attention will turn to weekly jobless claims numbers on Thursday and Friday’s all-important May jobs report.
Job opening and labour turnover data from Tuesday morning showed 8.059 million vacancies in April, the lowest level in more than three years.
