The Institute for Supply Management's monthly Purchasing Managers Index is closely watched because the people who do the ordering in factories often have a pretty good sense of the mood of their bosses. A reading above 50 indicates expansion in the manufacturing sector, while a number below 50 means contraction. Today's number was 52.7 for November, up from 50.8 in October. Better than expected.
