The Institute of Supply Management’s Manufacturing Activity Index fell to 53.5 in May from 60.4. This shows the pace of manufacturing activity moderating since the index reached a 7 year high of 61.2 in March. Add to it a decline in Conference Board’s Consumer Confidence Index from 66 in April to a 6 month low of 60.8 in May and the signs of a slowing economy are becoming very clear.
