ISM INDEX

August didn't prove that bad of a month for the manufacturing sector based on ISM data which show what could be described as no worse than mixed results especially for order readings. The composite index edged only three tenths lower to a plus-50 reading of 50.6 that still indicates monthly expansion in general activity though at a very slow rate.
