"Metal Industry Indicators" and "Stone, Clay, Glass, and Concrete Products Industry Indicators"

Metal Industry Indicators (MII) is a monthly newsletter that
analyzes and forecasts the economic health of five
metal-processing industries: primary metals, steel, copper,
primary and secondary aluminum, and aluminum mill products. The
MII presents composite leading and coincident indexes of a set
of indicators that historically have proven to lead or coincide

indexes were developed in cooperation with the Center for
International Business Cycle Research at Columbia University.
Each month, these indexes are analyzed along with any
economy-wide occurrences that would affect the metals
industries.
