June 6 (Reuters) - Wall Street was set for a higher open on Monday as investors await Federal Reserve Chair Janet Yellen's speech after a weak jobs report jolted markets on Friday, killing the prospects of an interest rate hike this month.
Yellen, who recently signaled that the recovering economy could support a rate hike as soon as June, will speak before the World Affairs Council in Philadelphia at 12:30 p.m. ET (1630 GMT).
Expectations for the next Fed rate hike were pushed back to at least July after U.S. May non-farm payrolls data on Friday showed employers added only 38,000 jobs in May, far below expectations of 164,000.
"We're coming off of a session where a wrench was thrown into many economic models after the weak jobs data and investors are going to be looking for anything in Yellen's speech that is going to address the weakness," said Andre Bakhos, managing director at Janlyn Capital LLC in Bernardsville, New Jersey.
