U.S. stocks fell, dragging the Standard & Poor’s 500 Index lower following its worst week of 2012, after employers added fewer jobs than forecast in March.

Equities slumped last week after the Federal Reserve signaled it will refrain from further monetary stimulus and concern about Europe intensified. The U.S. Labor Department said April 6 that employers added 120,000 jobs, the fewest in five months and less than the median economist forecast of 205,000. The amount had exceeded 200,000 for three straight months.
