ByJohn S. McClenahen The Institute for Supply Management's (ISM) new export orders index for manufacturing hit 60% in December 2004, up a substantial 5.3 percentage points from November's 54.7%. Credit a (relatively) cheaper U.S. dollar for at least some of the gain. ISM's December data show export orders growing in 12 industries, including primary metals, furniture, chemicals, computers, and electronic components.

Another 28% say their companies do not export from the U.S.
